Close current Tab

Rated 5 out of 5 stars

Thanks to the developer! it's comforting to see that at least some of my favourite add-ons are slowly being made into Web Extensions (or developed from scratch as such, like in this case.) This extension works just fine. The only complaint I have is the close button doesn't look "native". Dear developer, please consider including a native-looking simple dark "X" instead of the gradient-blue one.

Expression Search / GMailUI

Works great, with one small flaw Rated 4 out of 5 stars

I don't understand why so many people prefer web mail interfaces these days. I feel that a local client like Thunderbird is far more comfortable and flexible to handle, with one exception: The search function in GMail is more convenient to use than the one in Thunderbird. Expression Search / GMailUI brings the same functionality to Thunderbird. For me it works just fine, I couldn't observe any of the bugs that same others have reported in their reviews. However, I did observe one other bug: With this extension installed, the menu bar no longer works. It's still there, but no longer clickable. As all menu bar options are also available from the "hamburger" menu, this is not a disaster. It's still an acceptable trade-off for the added value provided by this extension.

Tab Sweeper

Perfect for "tab messies" Rated 5 out of 5 stars

@Developer: Like your wife, I'm a notorious tab hoarder. I don't like being called a "tab messie" as I keep tabs open "because reasons".
Whatever, I have tried various solutions over many years; from manual bookmarking or session management, to addons like TooManyTabs or OneTab. None of it worked ideally for me. Now Tab Sweeper is as close to a perfect solution as I've discovered - tabs automatically move on to a specific bookmark folder after a specific amount of time, and if they're not there I always know where to find them.
Here's two suggestions for improvement:
• How about an option to exclude a tab from being "swept", analoguous to "don't auto-unload tab"? In some cases, I want to have keep tabs regardless of how often I click on them.
• How about an option to sweep a tab to the swept tabs folder immediately? In other cases, I know I will not need a tab for quite a long time, so why wait for it to be swept?
Of course I understand if you (@developer) prefer to keep things as simple as possible and don't want to integrate any advanced features. But if that's not the case, I suppose these two features would be helpful to many people.

Reply to krxul Rated 5 out of 5 stars

Unfortunately it's not possible to reply directly to comments so I'm posting another review as a workaround.

Krxul wrote: "I've compared this extension between vimperator and pentadactyl,this one is slower when generating hints than pentadacryl and vimperator."

First off, even if this were the case, the comparison isn't really helpful. Both Vimperator and Pterodactyl provide much more functionality. This means they change Firefox's entire user interaction scheme fundamentally and also visually. They also take standard keyboard shortcuts (or "bindings" as Vim veterans prefer to call them) and give them new meanings. For users who have the standard keyboard shortcuts in their "muscle memory", this can be a nuisance. (To be sure, it's possible to change them, but considering the complexity, this is a tedious process.) It also turns out to be burdensome for users who sometimes work on other people's computers that don't have Vimperator or Pterodactyl on them.

By contrast, VimFx lets you do much less with the keyboard, but on the other hand it leaves Firefox's existing user interface, both the look and the keyboard shortcuts, entirely unchanged. Firefox will look familiar and can still be used with the same old shortcuts. Therefore Vimp/Ptero on the one hand and VimFx on the other hand appeal to quite different groups of users.

Secondly, I never experienced any noticeable delay in generating shortcuts with VimFx. I just tried again, and if Vimp/Ptero really are any faster, then this has no bearing whatsoever on my user experience. If your experience is different, then this probably has to do with other factors that may slow it down.

On a different note, for all the improvements that VimFx has had with recent add-ons, one thing is still missing. It would be more than nice to have the option to export/import the settings to/from a file - a function that many other extensions with complex settings provide.

And another thing: It's great that you can now bring up the tab history with a keyboard shortcut. However, it's inconsistent that it's not possible to go up/down in this list with h/j - instead you have to move your fingers from the homerow to the cursor keys. It would be great if support for h/j within the tab history can be added in a future version.

Great, but remains broken Rated 5 out of 5 stars

To be clear, I'm giving this five stars for the functionality it had in the past. Being a both a tab messie and "keyboard centric", I found this add-on incredibly helpful. Unfortunately, from FF 42 onwards, it longer works, as described by Seaonos below. That's why I was overjoyed when I found this in the available updates, but no such luck – it was an old update from 2014 that for some reason didn't happen earlier (weird).

Here's hoping that the developer (Tabby2 is a new version of the earlier Tabby that also stopped working at some point) will re-discover this, or that someone else with the necessary know-how will take care of it.

Session Exporter

One of the best extensions ever. Rated 5 out of 5 stars

Not much I can add to what I said in the title. Provides sorely missed functionalities and does so flawlessly. Thanks so much to the developer!

If I can make some proposals for further development: How about an option to export sessions or bookmarks at regular intervals? Also it would be great to be able to import stuff from HTML instead of just exporting it. Finally, a few options to tweak the HTML output would be useful - such as multiple columns (like Bookmark title, URL, date added, tags). Again, these are suggestions, not criticisms. :)

A must have for keyboard fans Rated 5 out of 5 stars

Being a keyboard addict, this in one of my most essential extensions.

I had tried Vimperator and Pterodactyl before, but found that they change the visual interface too radically for my taste. They also change most existing Firefox keyboard shortcuts, which are firmly engrained in my "muscle memory" (such as Ctrl F for find mode, etc.) It is possibly to undo those changes, but it takes a lot of time to reconfigure everything back to the familiar state.

By contrast, VimFx leaves existing keyboard shortcuts unchanged and merely provides additional ones. It is also very easy to configure to your own preferences - although this used to be even easier in earlier versions. Which takes me to some minor suggestions for improvements.

It used to be possible to change or delete individual shortcuts directly from the help screen. This is no longer possible; instead you need to go to the Firefox addons window, scroll all the way down to VimFx, click "options" and configure the shortcuts in there. The options interface is also less comfortable to use, as it's not possible to view all shortcuts at a glance. I suppose there is a reason for this, but I would still like it if the original could be restored.

Another feature I sorely miss is an option to export/import the settings to a file.

Finally, I love the new shortcuts for "tab history" and "recently closed tabs". However, they would be even more useful if it were possible to go up/down in them with "h"/"j" (or configurable keys). As it stands, you have to leave the home row and use the cursor keys - which is a bit odd when VimFx's whole point is to allow easy navigation from the home row.

It would be great if the developers could change this in a future version.

Long URL Please Mod

Yes, it does work. Rated 5 out of 5 stars

Contrary to what user Prozaque is asserting below, it does work perfectly fine. I was unsatisfied with the original "Long URL Please" because it doesn't support Bitly's shortcuts. Of course you may not notice any difference when you're just testing it with the URL shorteners that are already supported by the original add-on. Even in this case though it works just as well as the original one.


Good, but shortcut should be configurable. Rated 5 out of 5 stars

One of those add-ons that do exactly one thing and to it well. The only thing I don't like is the fact that the keyboard shortcut Control+Q is hardcoded and can't be changed.

It should also be noted that for Windows, AutoHotkey provides an easy way to get this functionality system-wide and put it on any keyboard shortcut you like, making this add-on unnecessary. But that's just for information, and doesn't reduce the usefulness of this addon for those who don't want to use AutoHotkey.

@drhouse: (Belated) thanks for the info about AHK and Greasemonkey in your reply. I use both, but of course they're not for everyone. Most people won't be willing to dabble with script stuff themselves. That's why I still think that it would be a good idea to make the shortcut configurable in your addon. :)

Disable Hello, Pocket & Reader+

Install things to uninstall things...?! Rated 5 out of 5 stars

For the record, I'm a long time user of Pocket, love the idea behind Reader View, and the only reason I'm not using Hello /WebRTC is that Skype and other instant messengers are already established so there's no point switching to a newcomer (a typical case of path dependence).

Here comes the "but": I still hate the fact that Mozilla has integrated them into the basic version of Firefox. These are all typical things that should be covered by add-ons. In fact, there has been a Pocket add-on for years that was user friendlier than the built-in Pocket handling, likewise there are plenty of "Reader View" type add-ons that are better than the one now built into Firefox. It's ironic that you need to *install* additional addons just to get rid of features that should have been addons in the first place...

Sorry if this turned out to be a general rant against Mozilla's direction rather than a proper addon review, but it just goes to prove how useful this particular addon is to begin with. ;)

Select like a Boss

Great - install and forget! Should be the default behaviour. Rated 5 out of 5 stars

Works fine in FF 42. As others already said, it's hard to understand why this isn't the default for copying link texts in FF. Are there any advantages to the awkward default behaviour that I'm not aware of...?
Anyway, this add-on takes care of the problem once and for all - install and forget. The only bad thing about it is its name. ;)

Squared Australis Tabs (Tb)

Great, thanks so much Rated 5 out of 5 stars

I loathe the "Australis" design. Fortunately, the add-on Classic Theme Restorer allows us to undo most of the damage in Firefox... but what about Thunderbird? "Squared Australis Tabs for Thunderbird" to the rescue! :)

Great, but constantly lagging behind Firefox releases Rated 5 out of 5 stars

The theme in itself is just great if you like the Tango theme or if you just want a more "colourful" look to the new monochrome Firefox standard theme.

However, every new Firefox release "breaks" it and it's back to the standard theme until it Tangofox gets fixed. :(

Just got the update to FF 42 and once again, this is the only add-on to be broken by it.

(Of course, this is caused by the non-semantic way in which FF has been pushing "major" updates on everyone regardless of actual changes ever since FF4.)

Edit @Developer: Just to be sure, you have nothing to apologize for of course. I do realize the delays are caused by the frequent (and IMO mostly pointless) changes in FF. Thanks for at least trying to keep up with this madness. ;)

Cutyfox URL Shortener (,,

Great! Rated 5 out of 5 stars

Works just great.

My only real complaint is that although you can decide whether or not the icon will show up on the toolbar, address bar and status bar, you can't disable it from showing up in the (right-click) context menu. That's the one place I don't want to see it, because I already have plenty of addons that put something in the context menu and it gets really cluttered.

Here's just another improvement idea: How about right-clicking on the button in the address/tool/status bar to access the options and/or quickly change the shortening service?

Oh, and the scissors icon may not be the best idea - people associate it with “cutting” stuff rather than copying. (Okay, I may be overgeneralizing. :) )


Good, but not perfect. Rated 4 out of 5 stars

This is an extremely helpful add-on that I've been using for years. But as they say, "the better is the enemy of the good" - that's why I switched to the fork "Advanced Locationbar", which linkifies domain and subdomain separately so you can easily move from "" to "". A few years ago, I was happy to give Locationbar² five stars, but now I have to downgrade it to four stars out of fairness to the Advanced Locationbar developer. Still, this is the original and as such deserves credit in its own right.

Creates "PDF images" only Rated 3 out of 5 stars

The PDF files created by this add-on are actually just images within a PDF "container" file, i.e., you can't copy and paste text out of them, convert them to .txt or .doc, etc. I thought maybe this was just a matter of settings, but if it is, the relevant setting is well hidden - I couldn't find it.
To be sure, for some people/usage scenarios, that may be just right, and *in that case*, it works just fine. For everyone else, this fact should be mentioned in the description.

Space Next

Very helpful for mouseless browsing Rated 5 out of 5 stars

I'm a huge fan of the VimFX add-on. One of VimFX's disadvantages was that it doesn't handle moving to the next page of Google results very well (you always need to look for the randomly created keyboard shortcut, usually consisting of two letters, to go to the next page). This is where Space Next helps you out: At the bottom of any Google results page, just hit the space bar and on you go. A little more configurability (is that a word?) would be nice to have (such as assigning another keyboard shortcut instead of space). Still five stars from me.

Tab Groups Helper

A must-have – even when you hate Tab Groups...! Rated 5 out of 5 stars

First off, I don't need the Tab Groups feature. I'm a "tab messie" and have plenty of them at any given time. Personally I feel that TreeStyle Tabs is the best tool to keep large numbers of tabs organized; Firefox's Panorama/Tab Groups just adds additional complexity. Although nobody is being forced to use it, AFAIK there's no way to remove or disable this feature completely. For some reason every once in a while I end up with two or more tab groups, with tabs mysteriously "disappearing" without a trace – i.e., being moved to (an)other tab group(s). This usually happens after crashes. Just yesterday I ended up with more than 100 tabs being distributed across no fewer than four (!) groups, some being duplicated in more than one.
Finally, this is where Tab Groups Helper comes into play: It presents all existing groups in a convenient manner and let's you easily find and move tabs between them – making it a life-saving tool for repairing things in situations like the one just mentioned.
To sum up - Tab Groups Helper is great if you like tab groups. And even greater perhaps if you don't. :)

PS: Tab addicts should check out the developer's other add-ons as well.

Good, but not flawless. Rated 4 out of 5 stars

I prefer addons with as few frills as possible, so this is right up my street. However, it only displays the first paragraph of the blog posts, even if the full text is available in the feed. Also, disaster strikes when you hit Ctrl+F (find in page): The entire bottom three quarters of the tab turns grey and will only go back to normal after restarting Firefox.
However, if you only want to look at the beginning of blog posts AND remember not to use "find in page", this is just fine. For all those who prefer a more comfortable (albeit more complex and imperfect) feed reader add-on, check out NewsFox.

Edit re developer's reply below:

Thanks for your reply.

Regarding "incomplete posts": I tested this with a number of feeds (all WordPress-based IIRC) and invariably only the beginning of the post was displayed, while the full text is visible in both NewsFox and Thunderbird.

Regarding Ctrl+F—it is perfectly possible that this is due to an incompatibility with other addons, as I have plenty of them (no themes, though). In no way did I mean to imply that this (or the other issue) is necessarily caused by your own addon. I was just describing my own experience with it in the setting I happen to have.

The thing is, personally I simply didn't like MicroRSS well enough to justify going on a time-consuming hunt for incompatible addons (or even sacrifice them in favor of MicroRSS) OR to bother its developer with a troubleshooting request.

Having said that, I can unreservedly recommend MicroRSS for anyone who is looking for a no-frills feed reader AND who either doesn't have the issues I observed or isn't bothered by them (I'm sure that's still a huge number of people). That's why I gave it 4 stars out of 5. :)

Quite good, but obsolete when using mouse gesture addons. Rated 4 out of 5 stars

Provides a useful function and works flawlessly just as advertised. However, it conflicts with mouse gesture (provided by addons such as FireGestures) and/or can be replaced by them, as it provides just a subset of mouse gestures in general. I suppose that most people who want to switch between tabs with their mouse will also want to go back and forward in the history, close tabs, etc., with the mouse. However, for those who want to use the mouse for switching tabs (and nothing else) this is just right.
