My Reviews


Rated 5 out of 5 stars

This works fine.

Please consider these two features:
- an option to only copy the URL without the title when pressing Ctrl+C
- an (optional) item on the main context menu to copy title & URL

This review is for a previous version of the add-on (1.1.2). 

YouTube™ Stop Button

Rated 3 out of 5 stars

Version 0.1.2
This desperately needs an update for the latest changes on YouTube.


¡Reiniciar! Rated 5 out of 5 stars

For some reason, it always says "Reiniciar" (both on the button and in the menu) even though I've never used a Spanish Firefox, I think (and most Firefoxes around here are either German or English).
It's a non-issue for me personally, just thought you might want to know about it anyway.

Other than that, it's a fair little add-on and does exactly what it's supposed to do.

Focus Regainer Lite

50/50 Rated 4 out of 5 stars

Whether this add-on works with your flash pages or not, highly depends on the wmode needed to operate that flash, because the add-on changes the wmode and thus renders some significant number of pages unusable while the add-on is enabled (they either don't load at all or they're missing parts or become unresponsive).

There's no risk involved with this - just be prepared that it may not have the same results on every flash page.

There's also not much the add-on can do about that.


1.7.0 (and Firefox Nightly 56) Rated 5 out of 5 stars

I'm not sure what issues exactly some people may have with this version of KeeFox but it works perfectly fine for me.
I'm using it in conjunction with the portable variant of KeePass 2.36 (and Firefox Nightly 56) and haven't noticed any significant changes since KeeFox updated from 1.6.4 to 1.7.0

This review is for a previous version of the add-on (1.7.0). 


very good - missing a "last active tab" option Rated 5 out of 5 stars

I primarily like this add-on for its functionality to avoid loading unloaded tabs when a tab is closed. It's the first add-on that actually does that quite reliably. (Of course the unloading itself works very well.)

What I'm missing though is an option that goes along with the one offered by other add-ons like TMP, to show the last active tab (no matter whether it's right or left of the current tab or if it's the one that opened it). Essentially the same as the last option already offered (to focus the tab that Firefox would focus - which it does), except it should still avoid unloaded tabs.

Maybe you could add that sometime, if it's not too much work.

This review is for a previous version of the add-on (0.7.2). 

Lazarus: Form Recovery

Sadly seems like it's dying.. Rated 4 out of 5 stars

This was great (except when it snapped and caused FF to slow down occasionally). Recently though, It somehow stopped working (on some newer version of FF/Nightly). While the add-on still gets loaded (even with manually enabled e10s forced onto it), the button claims that I need to enter a password to unlock, however, clicking it doesn't do anything. (The options dialogue works, so I can set and change the password, yet the button remains inactive.)

The web page seems dead, or I'd have created a support ticket or something.

Fun Wind

Yea Rated 5 out of 5 stars

That dog is great, and the way (s)he kinda seems to dissipate to the left.
The background is a bit too bright for my tabs (which in return makes it hard to find a suitable text colour).
That aside though, it's one of my favourite personas.

Reload Plus

Thumbs up! Rated 5 out of 5 stars

Does exactly what it says on the tin.

This review is for a previous version of the add-on (5.1.0). 

Load from Cache

Rated 5 out of 5 stars

Great concept. I've been wondering all these years why Mozilla wouldn't include a front-end option for much stricter cache loading by default, similar to the way Opera has rendered reloaded pages for a long time already.
I'm looking forward to one or two additional features to this, most prominently an adaptable white/black list (or just two lists anyway).
(Guten Rutsch und alles Gute für eine gesunde und erfolgreiche Zukunft..)


Left mouse button, Direct scrolling per multiplier (instead of scrollbar) Rated 5 out of 5 stars

Admittedly, this is a very efficient add-on and it does exactly what it says on the tin. (thus 5 stars)
As others have already stated, it's a convenient replacement for the "Grab and Drag" add-on, albeit it is much more minimalistic than the latter. Don't get me wrong, I love minimalism in the right places, I just have to say that I would prefer the way Grab and Drag actually "drags" the page directly (1 on 1 or with an added multiplier, similar to the way Acrobat scrolling works, or on mobiles/tablets), over just virtually dragging the scrollbar. I mostly just ignore the actual scrollbar anyway.
Also, the left mouse button should be an option.
Other than those two aspects, I think this is great.

This review is for a previous version of the add-on (2.2). 

Fire Drag

Thumbs up! Rated 5 out of 5 stars

Contrary to people like fremea, I find this add-on to be very useful and I'm glad it exists (thanks Eric), because
a) it mostly does exactly what it's supposed to do
b) at that, it does what I expected it would do (per its description!)
c) and it's simplistic which is always a good thing in my books.
d) On top of that, it works with e10s enabled ! (contrary to DragToGo+ 1.1.7.b19 etc)
It may have one or two very specific compatibility issues (with other add-ons that enable dragging anything or hook into any built-in dragging functionality) - but to say that it is useless and shouldn't even exist before another add-on, just because it doesn't have the same functionality as that add-on, is quite the brash aspersion.

This review is for a previous version of the add-on (0.1.2). 

Grab and Drag

Grab and Drag & e10s Rated 5 out of 5 stars

This has been one of the most useful add-ons to date, in my opinion, hence the 5-stars rating, as it greatly increases the flexibility of scrolling and allows to adapt that to your personal preferences, especially if you don't like FF's built-in autoscroll functionality - I've never liked clicking the middle mouse button ever since mouse manufacturer merged it with the scrolling wheel, which is fine, but pressing the wheel really feels odd to me.

As long as you don't enable e10s (Electrolysis, the multi-process architecture Mozilla's been working on since early 2009), Grab and Drag works fine even with FF 49, but it stops doing so completely when e10s is enabled.

If someone apt and skillful at these things would please adopt this add-on (or fork it into a new project, I suppose), that would be brilliant.

Duplicate Tabs Closer

Yea Rated 5 out of 5 stars

Works nice so far, does exactly what it says it does!

I'd have two and a half feature requests though:

1) Tab management add-ons like Tab Mix Plus often provide the means to duplicate tabs (including their history). Could you please add an option to keep two tabs (at least temporarily), so it wouldn't close a manually (intentionally) duplicated tab if there aren't more than two. Sometimes, duplicating a tab and then working from there is a lot more convenient than using the existing tab's history (let alone a new/blank tab).
(There's more, like, such an option should work with restoring a closed tab (that I may not consider a duplicate per se), as well as manually browsing to the same page (by accidental clicks or as an intermediary page), so, depending on your implementation, these may then be inclusive already, or they'd need discrete handling.)

2a) In addition to a dialogue or list or something (mentioned in other comments) to let the user choose/confirm whether to close a tab or not (as an alternative to the automatic mode) - some kind of notification would be nice as well. I'm not sure how this would look so it isn't too obtrusive, but it would be especially useful when the existing tab is way off on the tab bar. (Maybe combine the confirmation list/thing with the notification.)
2b) Alternatively (or additionally), maybe you could add an option to move the existing tab into the same position as the closed one. (I suppose this could make compatibility with other add-ons (and even FF updates) an issue when they don't conform, so it's something to be pondered.)

History Button

Rated 5 out of 5 stars

History Button works very well with Pale Moon 25.4.1 - no missing icon - and it is also excellently complemented by the add-on "History Submenus II" which provides an option to increase the number of items displayed in the drop-down menu, and the drop-down menu also shows History Submenus' additional submenus (which otherwise aren't visible with just the history sidebar).

The only thing that doesn't seem to be working is the "Show in Sidebar" link (in the drop-down menu) that should basically open the history sidebar - but that's something I can totally live without.

Flash Control

What's with the random "A" button? Rated 5 out of 5 stars

It works quite well so far, as in that it provides an additional stage of affirmation before certain flash animations or players are loaded (along with their content), like on YouTube so that pages load a tiny bit faster and the player is only loaded when I click the flash icon (in addition to YouTube Center which prevents it from actually playing the video).

There's one thing though, Flash Control seems to add a non-functional graphical "A" button to some pages, that does just nothing when I click it, particularly on Facebook where it mostly appears in the bottom left corner of the page. When clicked, the button just disappears Other than that, everything seems fine.

Rated 5 out of 5 stars

Tiny add-on, does exactly what it says it does, works very well together with TMP and various other add-ons, and is super helpful (especially with pinned, faviconised and unloaded tabs).

This review is for a previous version of the add-on (1.1.1-signed). 

Add to Search Bar

Rated 4 out of 5 stars

This has worked quite well on a couple of sites for me with Firefox 30. There are certain sites that don't work with it, like IMDb, which also doesn't work with the built-in function of FF to add search engines, so I suppose there may be certain difficulties on those sites, like too much Javascript concealing the search function etc.

This review is for a previous version of the add-on (2.5.1-signed). 

YouTube Unblocker

It works, mostly Rated 3 out of 5 stars

For me, it works most of the time, sometimes it doesn't and I need to disable it, then reload the page and re-enable it and reload the page so it applies the proxy (possibly a different one but I don't know).
Depending on people's location and the videos (and which YT server they are loaded from, and so on) certain proxies may or may not work. They may all work with one ISP and not work with another, so it isn't necessarily the add-on's fault.
It looks like it basically does what it says, or at least tries its best to do so.

Also, as other people have already mentioned, go to their homepage and load the latest version if it's newer than the one here on AMO. works noticeably better than 0.5.4

Supplement: After installing YouTube Unblocker, there occasionally appears an additional entry in the list of my extensions, it's name is something like "{53749993-9800-4dcd-9f5a-510edbd47675} 0.1" but it's different every time. It can be removed from the list with just one click and definitely originates from YouTube Unblocker. This happens as well when YouTube Unblocker is disabled. Disabling it also opens some kind of tracking link to Google which then just redirects to the Google websearch.
I highly dislike such behaviour. Please reason or remove. Until then, only 3 of 5 possible stars.
Feel free to respond in either English or Deutsch.

Download Status Bar

Rated 5 out of 5 stars

Works quite well. Thanks for maintaining this addon (as a continuation of Download Statusbar).

On a side note, anyone having issues with 8.0.0+ not showing the downloads bar at all, might want to install at least version 8.2 (from the complete version history as long as it hasn't been reviewed by mozilla yet). That should fix the bar, at least it did for me.
