Case Change Tool

SpLeNdiD. Strike-thru enhancement please Rated 5 out of 5 stars

I found this for a friend of mine who doesn't touch-type either.
FASCINATING that it works on 'protected' web text as well.

Two requests:
I would really like the ability to S̶t̶r̶i̶k̶e̶t̶h̶r̶o̶u̶g̶h̶ selected text (perhaps \\ as well).
WTFM! (Write...) I know it's terribly tedious, but PLeAsE, just a little documentation? Rather than having us guess and tax our ESP abilities?
It's very easy. Here: "Highlight text, right-click, select type of change from CaseChange sub-menu (hover), click. Works on text outside text-boxes too, by changing page source."

I don't know if it's possible to do effective italicisation/embolding/underlining by this route. I use hotkeys for those.

I like Sarah Jade's suggestion to have single-letter selection from the change-case sub-menu (U, L, S etc.. Shift key would be cute).

Next I nede something to corrrect my typos. But that would be bloat.

no button Rated 3 out of 5 stars

Seems like a good idea.
However the essential icon button is absent in current FF.
So cannot invoke the process.
(Maybe it is on the defunct status bar.)

Also, could there be options, including the Wayback engine?

Addon List Dumper (restartless)

now not working in Firefox 39.0 Rated 4 out of 5 stars

UPDATE: the next day, after a linux update, the list icon has reappeared. It's usable but not perfect. (returm to "****")
Save-to-clipboard seems not to work.
(firefox:3157): Gtk-CRITICAL **: IA__gtk_clipboard_set_with_data: assertion 'targets != NULL' failed
print works, save-to-file seems not to work.
One can usefully copy-paste from the display panel.
Options do not persist between calls.

Was not exhibiting the icon it needs to start the process. (fixed after linux update next day)

I surmise that FF devs have turned the 'deprecated widget' handler into a hard fault, which has broken at least one other extension. (fixed at higher level?)

I hope this can be fixed! (Please)

The other list-extensions addon (needed re-start) from 2011 wasn't working for me, by the way.
If you are a user in need of a list of addons, and if this is not working for you, you can try about:support (in the address bar).

Disable Hello, Pocket & Reader+

Rated 5 out of 5 stars

Since it seems impossible for me to leave a full review here without it being censored by some unknown hand (I thoroughly disapprove of that, btw), I'll just say a thanks to the author and leave some stars.

This review is for a previous version of the add-on (0.4.1).  This user has 2 previous reviews of this add-on.

Flash Control

not sure Rated 4 out of 5 stars

I'm not sure exactly what this does - is it only to stop video autoplay, or does it change any flash parameters?
Does it actually enhance privacy by stopping flash leaking IP info (as I've seen claimed elsewhere), or merely optionally turn off the plugin?

Meanwhile, I'm getting annoying hangs (linux, limited memory, so not necessarily this extension), with nothing remarkable in the process manager, not even plugin-container over-running (as it does).
One anomaly I do see is (running FF in console):

** (firefox:5269): CRITICAL **: gst_app_src_set_size: assertion 'GST_IS_APP_SRC (appsrc)' failed
console.error: flashctrl:
Message: Error: The page is currently hidden and can no longer be used until it is visible again.

I'm not using any private windows or hidden pages that I know,ut this could be a technical thing. How critical is it?

Disable Hello, Pocket & Reader+

Review vanished. Was is censored? - reprint part 1 Rated 5 out of 5 stars

Originally posted Pocket day zero, 17 June 2015, this review (and reply) subsequently vanished. Strange, unheard-of.
I certainly didn't rescind it.
Maybe it was censored by a robot, or by some touchy element of Mozillla. (Is it permitted to criticise Mozilla? This isn't exactly the right forum, but some criticism is relevant.)

Let's see if we can narrow it down.

review Part 1 ~~~~~~~~~~~~~~~~~

You were quick off the mark!!

Pocket introduced today and I've already been able to dump it.

What a sell-out by new Mozilla!

Giving this five star in faith that it works.
It may keep some bloggers alive a little longer.

I had already changed about:config to browser.pocket.enabled;false
which is still there (good), but it means I can't tell if you did it! ;-)

I applaud disabling of the geolocation feature in webRTC,
What about disabling the other .peerconnection. config entries?
(filter [media.p] works )
I am unsure what exactly they do, if they leak or are necessary for function.

I don't know much about 'hello', wouldn't use it myself. Gone now, thanks.

Twilight zone Rated 5 out of 5 stars

My review and your reply seem to have disappeared here.
I wonder why.

Thankyou for the advice re "location guard", but I am also concerned about possible obfuscated code in FF and the tendency to hide 'features' which would be useful for malware and general snooping, putting everyone at risk.
Like for instance the high and unannounced value of config

I must go fetch my tin hat again.

Addon List Dumper (restartless)

yes, very good, but Rated 4 out of 5 stars

I am grateful for this add-on. It works well, whereas the other extension list dumper doesn't work at all for me, and copying from about:support isn't that convenient.

when I run FF in a shell, at start-up (even before using the extension) I get
console.error: addon-list-dumper:
DEPRECATED: The widget module is deprecated. Please consider using the sdk/ui module instead.
plus a whole load of non-fatal whingeing with traceback (which may be unrelated).

Consider, it would just be neater if that were fixed.

Request (I assume it may not be that easy to implement):
I would like to see the entries contain the actual download URL, eg the "", or at least the proper URL-name which I could use to reload from, as well as the support site where known, rather than a hotch-potch of some firefox/addons/ and some support sites.

That's because the AMO search doesn't always find the addon from the 'name', but then the AMO search is so generally useless that often I have to resort to a websearch anyway.

And date-last-updated as well as date_installed.
And whether it is restartless on not.
(and signed or not)
(and review status)
The name of the add-on developer would also be useful.

But yes, very nice, certainly good-enough. Good work.

Adblock Edge

Thank you Rated 5 out of 5 stars

Thank you for your efforts over recent years.
Please feel validated :)


poor choice of hot-key; panel does not identify itself clearly Rated 2 out of 5 stars

The hot-key chosen by the author interrupts the existing standard hot-key for entering Unicode characters in hex: control+shift+U +four-character-hex-from-number-pad.
(websearch control+shift+U )

When I try to enter a Unicode character this way, instead I get the user-agent pop-up box, which, because it is anonymous, took me some time to track down (I had installed this a while ago & not used it).

First suggestion: please do not hijack existing standard key combinations

Second suggestion: please clearly identify the pop-up, so we know where it's coming from & can remove it if need be, without wasting half an hour tracking it down.

Third suggestion: an icon to invoke it would be better, perhaps with a drop-down choice, rather than a pop-up.

4th: then an /optional/ & /configurable/ hot-key for those that want such a thing.


I suppose one might /guess/ that clicking on a particular browser icon in the panel should change the user-agent.

It would have to be a guess because there's no instruction or help or clarity on the panel.

I understand that one can "enter one of those pre-defined values" for an agent, but in the panel there is no clue what might be acceptable, no drop-down, no Help, no reference to the instructions page.

(And there is no syntax check, if one enters one's own string. Although one could use 'whatismyuseragent com' for that.)

But, it does work.

A useful enhancement would be to have an icon which indicates the current user-agent status.

Vertical Toolbar

Praise & requests/suggestions Rated 5 out of 5 stars

Splendid concept. Well done. Thank you.

I would find Australis (FF29.0+) unusable without it, since I like to see status indicators e.g. Quick Java add-on, as well as unhidden access points.

It also frees up space on the Nav Bar, which otherwise would be intensively cluttered.

Regret I could not access (maybe just temporarily today 20 May 014); could you put a valid support site in the description, please?

What concerns me is that I now have a highly customised FF-Chrome-panel + VerticalToolbar configuration, and I see no obvious way of saving, restoring or reverting that, should disaster strike.

I like it that most buttons fit in a narrow VerticalBar without making it wider. Regrettably, the [QJ]v Quick-Java drop-down is an exception - but I can put errant wide icons in the Nav bar, because of space freed up there.

I found out which buttons caused widening VerticalBar problems by trial and error analysis. It would be useful if wide buttons were somehow highlighted.

It woud also be useful if there was easy access to the FF 'Help' menu (now FF29.0+ hidden away by Mozdevs, when it 'should' be prominent & obvious), and to the Menu bar (also hidden away behind severlal clicks) - in particular the Tools button.

Currently to find MenuBar-Tools, one must right-click on, say, the 'newtab' + symbol or Chromium button, select MenuBar, which then appears top left of screen, and go from there.

A direct access MenuBar drop-down in the VerticalBar would be ideal; even better would be direct access to the Tools drop-down.

Final question: Is this extension Tor-safe?

Praise, thanks, works fine in FF29.0 (and usability gripe 29.0) Rated 5 out of 5 stars

Still works nicely with Awstralis, I'm relieved to say.
One of the essentials.
Much praise and Thank you.

I have put the [JS] button on the nav bar (for emergencies!), and the [QJ] button in the new C̶r̶o̶m̶e̶ FF tweak panel.

That nav bar is going to fill up very quickly with status indicators!! I hope all indicator icons I use there will soon have a 'microscopic' option. (It seems to be a mozilly decision to insist on biggish icons.)

One small usability gripe is that one can only change one option at a time in the [QJ]v drop-down; I change any one setting and FF bounces me out again, so I have to dig my way back down to change the next.
I suspect this too is more a FF usability imposition than anything else (?).

Even more confusing is that if I click the [QJ] itself, it toggles all settings but one never sees the change (because again, FF immediately bounces me out) - I would have to dig down again into FF tweaks if I wanted to check the status, but I guess I trust it by now (probably a bad decision...).

Also, it isn't explicit that right-click on the [QJ] will bring one to the hidden QJ option panel, something one finds by guesswork. For new users it might be advantageous to have an explicit "options" choice in the drop-down. It's moot.

btw, what does "reload on change" mean?
Am I being dense or have I missed some documentation somewhere? (Reload what to what on change of what?)

One further question - when I toggle JS (or J) to 'off', does it actually stop/kill the relevant background processes, or does the setting apply only to new instances?
My preference would be for killing off rogues in the backbround.

Classic Theme Restorer

aaaaaustralis :( Rated 5 out of 5 stars

Thanks. I dread change when it is for the worse; this goes some way to keeping FF usable.

Feature request: could you add the ability to delete Australis devs?

Half a league, half a league, half a league onward ....

what about the future? Rated 5 out of 5 stars

QuickJava is one of the add-ons I consider essential.

I love to see an immediate indication of plug-in status, rather than having to remember, or guess, or trust to luck.

I love the ease of switching, instead of having to delve into the innards many clicks and delays away.

Unfortunately the #!FLAME*#ing arrogant moz devs have in their infinite false wisdom decided to go the route of dumbing down & removing useful features from Firefox in an effort to really annoy me.

We've already seen that kind of sabotage when they removed the easy JavaScript switch feature, ostensibly to protect users from deeply technical solutions by pointing them at about:config instead - choosing the wrong solution to the wrongly perceived problem. Exasperating.

In the coming Australis perversion of Firefox (which is not all bad, just mostly bad), one of the devs' "helpful" dumb moves is to completely remove the add-on bar. Another has been to ensure that FlashBlock does not work sensibly. (Not to mention what they are doing to tabs.)

Another is only to listen to selected users, it seems, as in "talk to the hand".

For those who've been kept in the dark about Australis, see an enthusatic but less-than-open blurb here:

Read the comments. Someone has to. Find out about it. Try the "nightly" (QJ won't work). Complain loudly!How will QJ cope with this dash for idiocy?

Will QJ be able to cope with it?

Will you be dependent on fall-back addons reconstructing some kind of non-native addon-bar, an extra potential point of failure (given recent history of great addons being rendered unusable from time to time by FF auto upgrades, not good).

I wouldn't see it as being useful to clog up the navigation bar (soon to be the one_&_only everything-to-everyone Swiss Army navigation, search & status bar) , which seems to be the dev favoured solution.

I would be devastated to lose QJ.


One other thought - the indicator/switch icons don't really need to be so large, unless one is looking for an accessibility option.

(Oh, and smaller icons customisation is to be killed off by Australis, too, in an apparent desire to economise on screen space ???? Go figure.)

YouTube Flash to HTML5

Rated 3 out of 5 stars

Problem - no longer works in FF 25.0.1 (under Linux mint 15)

Nothing plays.

I think it has something to do with insane 'improvements' by current FF devs in the path to Australis & onwards down the drain.

Flash Block

Rated 4 out of 5 stars

Problem - no longer works in FF 25.0.1 (under Linux mint 15) (JS is on)

Thanks - this used to a 5-★ ★ ★ ★ ★ essential, but sadly now suddenly it does not do anything, for example youtube plays straight away.
Also recently I've seen the (f) appear briefly, then leave a black unresponsive box.
Fail both ways.

I think it has something to do with insane 'improvements' by current FF devs in the path to Australis project & onwards down the drain.


I hope you can mend it.

And since Flashblock must be one of the more popular add-ons, perhaps could you influence the FF dev crowd not to be so damned arrogant?

Love & peace...

Add to Search Bar

Rated 5 out of 5 stars

Tags? The perennially annoying 'new' AMO doesn't find this if I search for 'add to search bar' (or permutations). It should surely come first on the list.

Excellent addon, essential.

Mainstay add-on! Simple explicit unobstrusive effective.Thanks for the prompt update to cope with the FF 23 lunacy which disabled the Java toggle. At least Mozilla managed to adopt your fix fairly quickly.

Feature request:Do you think you could add a L toggle to undo the effects of Lunatic development decisions at MozHQ?

Flash Video Downloader - YouTube HD Download [4K]

Repair needed ! ... and promptly supplied! Bravo! Rated 5 out of 5 stars

Was wonderful,

I have been relying on it.

Just recently (Feb 2013), 3.8.2 just does not work any more.It detects the video, shows a blue arrow, but the full-mode panel says "nothing to download or video not playing" (it is playing).

Five stars in the hope & trust that it will be fixed soon!

I'm disappointed each time I check and still see 3.8.2.

I am currently using Linux mint 14 64-bit, with firefox 19.0 for linux mint 1.0


Thanks, Pavel for the emailed update (for linux), which appears to work well.

Ah, I see, you are waiting in the queue for Mozilla approval
and the working version is at

(download the .xpi and drag/drop it to FF awesome location bar to install)
Thanks again.

Invaluable Rated 5 out of 5 stars


Still 5★ but sadly overtaken by events - to whit, the HTML5 media player, so the utility of switching off Flash is sadly reduced.

Very useful on restart; it can stop cpu/gpu-intensive processes loading in the background, speeding up a restart when FF gets clunged up, & preventing background annoyances.

One of the best features was to allow me to switch off all the Adobe Crash player processor hogs, playing annoyingly in some un-findable background location (especially at restart).
Sadly, this no longer works so well as some sites intrude again with HTML5 video/audio, or even switch to HTML5 if Flash is unavailable.

These might be helpful for user, but I'm not sure how straightforward it would be to implement them
1) Add switches for whatever media player is appropriately installed. For Linux + Gnome this is often Totem {see e.g. WP /Totem_(software) }. Ditto mplayer etc. etc
2) Add a switch to halt HTML5 media plays (somehow)
3) Add a switch to kILL plugin-containe(r). I find in Linux that a >pkill plugin-container often frees up FF when it is slow or stuck, even if the container is quite small, not full of leaked memory. If this could be added to the 'off' Flash process, it might be advantageous for the average user.
4) It is wonderful, & necessary, to switch 'services' globally. In an ideal world, it would be really nice, additionally, to be able to switch things on/off for the current page only. That's probably a rather different extension - there are addons that do this piecemeal, but conversely they don't work globally.

There is some discussion here about the row of status/switch icons & their size.
Yes, a sensible reduction in the use of screen real-estate is often welcome. The spacing & size might benefit from being customisable.

However, I like to see - want to see - the status of each 'service' at a glance, not hidden away behind another button to click.
That would be an abomination, IMNSHO.

It's plain daft to hide status indicators. They needn't be too big, though, so long as they are clear.
