Regex Search

Rated 3 out of 5 stars

I like the recent Highlight feature that's been available since version 1.0.4 (for some reason only available as a download from the author's GitHub page), but it has one side-effect that has a massive potential of breaking websites. The highlight is not only applied to visible text within tags, but to the whole page ( document.body.innerHTML ). This can break inline JavaScript, link references and all kinds of other things as well if a match is found, which sadly makes it unusable as the multi-word highlighter that I've been looking for.

For other use cases, such as extracting data from the page source, it's a neat extension but I have no such requirements myself.

Rated 5 out of 5 stars

Legacy extensions have been disabled now and that also means the way of injecting custom JavaScript into web-pages has changed in a major way. I've reviewed this extension a little more than a year ago when WebExtensions for Firefox were just starting to pop up more frequently. Since then it has become ready for productive use, as none of the issues I encountered last year remain. For that it deserves the full rating.

There's just one little thing to find fault with and that's the advanced editor. You're less inclined to need it as a pure user, but when writing or modifying userscripts, it has been helpful. For some reason it runs buttery smooth on Blink-based browsers such as Chrome or Opera, but use it in Firefox and the extended functionality keeps freezing the tab or textarea for short periods of time. The syntax highlighting is actually fine, but the JSHint-based syntax checking doesn't work nearly as well as it does on Chrome. This is annoying because it distracts from writing code on-the-fly and why I've started using a third-party editor to copy/paste my results over from.

Edit: a comment to another reviewer: the new tab that opens with every extension update is indeed annoying, but this can easily be disabled in the settings (-> Appearance -> Show TM update notification: Disabled -> Save).

Undo Close Tab Button

Rated 5 out of 5 stars

I've tried several similar extensions originally taken from the Chrome Web Store, because they offered a number of nice features such as pagination or a search filter, but none worked properly with Firefox.

This extension has no such issues. It not only reopens the tab as requested but it also retains the past browsing history so you can keep navigating back. It also integrates well with Tree Style Tab, in that a recovered tab goes back to the exact position it had in the tree before it was closed.

If there are any things that could be improved it would be to replace the outdated screenshots on the Firefox Add-ons page and to disable the context menu on the popup panel.

Undo Close Tab

Rated 4 out of 5 stars

It's pretty good actually, The icon is clearly visible on any light or dark themes I have tested and it also uses the context menu design of the operating system.

The only downside - and also the reason why I'm uninstalling this again - is the lack of configuration options to set it up for my needs. I need to be able to open the list of recently closed tabs with the left mouse button, because in most cases I don't want to reopen the last closed tab. I'm not confident that I could learn to make an exception for this extension, when all others I use have to be operated with the left mouse button instead.

It's nice to be able to trigger two different actions depending on which mouse button is used, but with no way to configure the underlying action, this design decision goes against the grain of virtually all modern extensions. That's why I can only give four stars for an otherwise great and helpful tool.

Windscribe - Free VPN and Ad Blocker

Rated 1 out of 5 stars

This review is for a previous version of the add-on (2.3.4). 

Firefox Multi-Account Containers

Rated 5 out of 5 stars

This is a fantastic extension, not only because it reduces the requirement of multiple browser profiles and thus the complexity despite allowing a certain separation between browsing sessions, all in the same window. The easy integration into tab-bar/tab-based extensions (such as Tree Style Tab) make this into an essential tool to increase your usability. For me it's a stand-out feature that no Chromium-based browser can offer.

Tab Open/Close Control

Rated 5 out of 5 stars

I'm using this in conjunction with the 'Tree Style Tab' extension because that one adds some new tab behavior and not all the options to change it to my liking. Hence some other extension was needed that got me back the functionality I had with 'Tab Mix Plus' in versions <=56 of the browser (After Close, Change to Last Active Tab). It also does not appear to interfere with the grouped tree behavior when opening tabs. All in all, I'm happy with it.

Edit: if there was one thing to criticize then it's to make the extension page on AMO more user-friendly. Add a more detailed description, maybe create a graphic/modified screenshot to illustrate the changes that are possible. I don't need any of this, but for the average user it would undoubtedly help

Magic Actions for YouTube™

A very good Youtube helper Rated 5 out of 5 stars

I've been a long-time user of the Youtube Center userscript, but the developer hasn't been very active on it lately which made it increasingly problematic to use the script on Youtube.

On my search for a properly working alternative I have tried several scripts and browser extensions, but Magic Actions is hands-down the best of them all. It offers all the features I require and their privacy policy is good too.


A mixed bag Rated 3 out of 5 stars

As a long-time userscript developer I am very familiar with this extension on Chrome. The functionality of Tampermonkey is so much better than that of Greasemonkey and it is running like a dream in any Chromium-based browser too.

Sadly the same cannot be said for this iteration of the extension. Tampermonkey for Firefox is at times horribly slow (most notably the script editor itself frequently makes the browser hang for seconds), it starts chewing up memory in insane amounts (at the time of this writing I'm looking at about:memory data of almost 900MB that has built up over the day, despite only a handful of open tabs and less than ten small scripts) and it also doesn't appear to be very optimized for the Fox yet (I'm seeing scrollbars in the icon's pop-down menu on any website a script exists for).

I cannot tell who to blame for these issues, but at least in my case Tampermonkey is not ready yet to be used with this browser. The great feature-set will surely keep drawing me back here, but until then I'll be stuck with Greasemonkey (which is dependable but not spectacular).

PiP Video

Does what it advertises, but ... Rated 4 out of 5 stars

... sadly, I could not find a way of getting it to work in conjunction with the auto-play function. Technically speaking, this extension pauses the playback of the original player on the Youtube-page in the tab and creates a (modified) copy of the player for the pop-out.

In my eyes this is the one major weakness of PiP Video and the reason why I'm uninstalling it again, because I watch a lot of shorter videos and it's just not something you can do comfortably with this extension. Moving from one video to the next means that you have to a) focus back on the browser and the Youtube-tab, b) advance to the next video in line manually and c) click the pop-out button of PiP Video.

I have to admit that I don't even know if what I'm wishing for, a fully automated playback of all videos in a playlist or the use of the Autoplay feature, is even possible with a Firefox extension. The one thing I do know however is that Opera ships with a built-in pop-out video feature that supports Autoplay and it is an superior alternative because of that.

User Agent Switcher (Firefox)

Not fit for wide-spread use Rated 1 out of 5 stars

I have to agree with all other previous reviewers, that this extension should not be installed or used as it exists now, because it clearly does not offer a comfortable way of setting it up. On desktop Firefox you get an address-bar icon which lets you configure the user agent, but there is no such thing on Android. Even then it would less than ideal, because there's no way to set a custom user agent anyway.

By the way, I did get the configuration to work on Android too, but nobody should be forced to go through these tedious steps that were never intended to be made by end users. For me it worked like this: try typing "moz-extension:// into the address field of the browser and you *should* receive a suggestion for an url ending in "IndexedX_background.html". Take that link and replace the quoted part with "popup.html" and then access said page. Any changes made there will modify the user agent of your browser. I'm sorry to say that simply copying a complete link here would not work, because Firefox chooses to set a random GUID for the extension at the time of its installation, which makes everyone's link to this normally hidden page unique. For clarification: "popup.html" is the menu/mini-page you see when clicking on an extension icon. It is possible to access it directly if you know where to look.

Google Redirects Fixer & Tracking Remover

Rated 5 out of 5 stars

I previously used the "Don't track me Google" userscript, which did alter Google's redirect and thus their knowledge of which links I click on the search page, but it also introduced its own (local) redirect. It was okay for privacy but not for comfort.

So, FINALLY, I've found the perfect solution in this addon! It does exactly what I have always wanted and it works silently in the background.

Thanks for creating this piece of comfort.

Thanks for this update. It fixed the LastPass-error I mailed you about, now everything is working perfectly for me!

Ghostery – Privacy Ad Blocker

Rated 4 out of 5 stars

This is a must-have extension, because it removes so much unneeded clutter from surfing the web. Thanks to a white-list and the easily accessible disable/pause function for the whole blocking or for single sites, Ghostery is the perfect companion for any Firefox user.

My only issue - which is admittedly small - is with the navigation bar icon of Ghostery. It's truly minor, but the icon constantly changes size from one tab to another or from one website to the next. These repeated resizes drive me crazy, which is why I don't use the icon anymore. If we could get a fixed-width button (or an option to disable the number being displayed), Ghostery would deserve a full five stars.

Rated 3 out of 5 stars

I'll give this a three stars review for the idea of it only.

WARNING: Unfortunately, as others have reported as well, this extension has a major impact on browsing speed and makes regular use virtually impossible!

Some years ago, way back when Firefox 3.x was current, I tried to use a similar extension called Breadcrumbs and it had the very same issue.

I guess, that you're using an sqlite database to store a user's browsing history. Larger single-file databases like this are a well-known source of performance problems.

I would suggest the creation of a native (windows) application to get rid of the performance problems. With proper database and indexing features available in this way, you could create much lighter extensions to the major browsers that would do little more than report everything to the native application, request any data from a user search and generate no performance loss in the browser itself.

At least that's the way I would do it, because in its current form, archify has just been removed from my browser again.

Super Start

Good likeness of Opera's Speed Dial Rated 4 out of 5 stars

This extension is great, let me say that at the beginning! It does mostly what I am used to from my Opera installation, it is just as customizable if not more so and it is surprisingly fast.

The only things I miss are two features, one functional and one entirely for nicer optics:

1.) Please introduce a setting which allows me to disable the entries in my right-click menu. I don't need them both in the context-menu for tabs AND the website itself, one is more than enough for me.

2.) My speed dial squares don't have any mouse-over effect. I have been using Opera for years and have gotten so used to that - now I'm missing it hugely.

Oh, I almost forgot: you have folders just like the new Opera Next 15, which is great. But could you introduce a feature, which can open all tabs within one folder at once? Maybe a context-menu entry or an option to use the middle mouse button (because that only opens another Super Start tab right now)?

Live HTTP Headers

Rated 5 out of 5 stars

Five stars for this awesomeness.

I tried a similar extension for Google Chrome, but only found something incredibly unstable with bad handling on top of it. Only Opera included a HTTP header sniffer in its Dragonfly developer utility, but since that version of the browser won't receive any updates anymore, Live HTTP headers looks to be the only solution that works conveniently from within a browser.

Great stuff, I'll start using it more and more in the future as I phase the old Opera out.


Rated 4 out of 5 stars

Four stars from me.

The extension does what it promised and it does not cause any issues. In short, I'm happy with the result.

A pre-made alternative design with black or dark text on light background (the one that exists is way too blurry) - or the inclusion of images into the button, as I've seen it done elsewhere - would have made this a five star review.


Rated 5 out of 5 stars

I have been annoyed with Firefox for a long time, because it didn't keep the current zoom saved in the session. After a browser re-start, every opened tab was always back to 100 percent.

That's why NoSquint works so well for me: it does exactly what I like and there's no need for extensive configuration - which I could expand upon of course, if I needed it.

Great extension!
