Crashes FIrefox, breaks free websites, outdated, breaks NoJS-Fallback Rated 1 out of 5 stars

Everything tested with a stable version of Firefox and Dev Edition.

So here is what this add-on did:
1. It crashed (both) Firefox directly after installation.
2. As a web dev I tried to adjust some external JS files using magnet URIs. This resulted in:
2.1. At first one file was recognized as "free", but it was at the same time recognized as "non-free" in the view.
2.2. Later all of my files were recognized as non-free even though all had magnet links marking them as free. There was always a "parsing error" shown in the list.
2.3. The default excluded libraries do not include jQuery 3.1.0 (the latest jQuery version), so I could not use the hard-coded excludes as they were just outdated.
3. The option to show what LibreJS currently analyses slowed down the loading process of the website dramatically and I could not see anything. So I basically could not use this option.
4. LibreJS broke <noscript>-Fallbacks, so it is even worse than if you would have JS completely disabled.

Also the design is ugly, but this is of course very subjective.

Slim Add-ons Manager

Nearly perfect Rated 4 out of 5 stars

There is only one thing missing: When one addon is selected the addon should show this item in the default state. This would be some kind of "expand when selected" mode.

Disable Visited Links

Does what it says Rated 4 out of 5 stars

It does what it says - and I never knew about this thing before.

However I'd like to be able to whitelist sites where this is always (automatically) enabled.

Disable WebRTC

Good addon for enabling/disabling WebRTC Rated 5 out of 5 stars

Does what it says and - especially - you can toggle the state of WebRTC on the fly.

The only thing I'd like to see is that the source code would be hosted in a repository (at GitHub or somewhere else), so you have a nicer way to get to the source than by using AMO here.
What's nice is that it is already open-source. (MPL)

Edit: Okay, nice. Next time just already link to the repo in the description. :)

Sends browser history to SimilarWeb, problems with working Rated 2 out of 5 stars

Read the privacy policy! (
This add-ons sends data to SimilarWeb - including your IP address and browser history. You can turn this off, but it's said nowhere else - except the privacy policy (which isn't read by many people) and a setting. Additionally I don't know why you do this, Plugin-Paul - do you get money for that?

Additionally it often didn't work. Some times the the Java/Flash updaters informed me earlier, but maybe that's fixed in the latest version.

WebRTC Control

Does its job, but it could be nicer Rated 4 out of 5 stars

At first: It works.

But there are some things which could be better:
1. On it claims this add-on is Open-Source - however I could not find the source anywhere. The link "Fork me on GitHub" goes to and even a manual search there didn't show anything.
2. The icon is ugly. Sorry, but the icon is not really nice. The part which changes is too small and you can not easily difference between the states (on/off) - especially when you move the icon to a smaller place like the add-on bar.
And the white background looks ugly too.
3. The FAQ question "How do I change my DNS address?" is very confusing as there is no relation to this add-on. If you add this question there you should at least explain why the user should change the DNS address at all.

*Edit:* As the developer has addressed this issues I'll add one more star.

This review is for a previous version of the add-on (0.1.0). 

Quick Gestures

Nice addon Rated 4 out of 5 stars

It's a nice addon but lile others said thing the undoed tab doesn't work and it also doesn't seem to work at the home tab page.


Kleiner Fehler im Add-on / Small bug in add-on Rated 5 out of 5 stars

Folgender Fehler ist mir aufgefallen: Wenn ich den Add-ons-Manager bereits in einem Tab geöffnet habe und bei dem Plugin-Check-Button auf "options" klicke, wird der aktuelle Add-ons-Manager geschlossen und in einem neuen Tab geöffnet.
Wenn der Add-ons-Manager angeheftet ist, wird er dabei sogar abgeheftet.

I noticed the following error: If I click on "options" in the plugin-check-button then the actual opened add-ons-manager will be closed and reopened in a new tab.
If the add-ons-manager is pinned it even will be unpinned.

Edit: Ich habe Version jetzt getestet. Das Problem ist, dass jetzt die Einstellungen des Add-ons nur angezeigt werden wenn der Add-ons-Manager entweder geschlossen ist oder wenn er gerade in einem Tab geöffnet ist und dieser Tab auch angezeigt wird. D.h. wenn der Add-ons-Manager in einem Tab geöffnet ist und dieser Tab nicht ausgewählt ist, dann passiert gar nichts.

Sehr nützliches Add-on / Very useful add-on Rated 5 out of 5 stars

Dieses Add-On ist wirklich eine sehr sinnvolle Auto-Update-Möglichkeit für die Plugins.
Es wäre allerdings noch schön wenn die "Animation" beim Suchen für Updates diskreter gehalten werden könnte bzw. sie ausgeschalten werden könnte.

This add-on is really a great auto-update-checker for plugins.
But it also would be nice if the animation during update-checking could be a bit more discreetly or you could add the possibility to deactivate this animation.

Location Bar Enhancer

Sehr gutes Add-on / Very good add-on Rated 5 out of 5 stars

Dieses Add-on ist praktisch und sieht zugleich gut aus. Es ahmt sehr gut die vom Windows-Explorer bekannten Pfadanzeige nach.

This add-on is very practical and it also looks great. It imitates the path display of the windows explorer very well.

Progress Bar on Tab

Funktioniert nicht mit Firefox 29 / Don't works with firefox 29 Rated 1 out of 5 stars

Mit Firefox 29 funktioniert es nicht, auch wenn die Add-ons "Tab Scope" und "Colorful Tabs" deaktiviert sind. Es wird einfach keine "progress bar" angezeigt. Es wäre schön wenn die Unterstützung für diese Version eingebaut würde, denn dieses Add-on ist von der Idee sehr gut.

It don't works with Firefox 29, also when "Tab Scope" and "Colorful Tabs" are deactivated. No progress bar is shown in the tab. It would be nice to add support for this firefox version, because this add-on is a great idea.


Gutes Add-On mit vielen Einstellungsmöglichkeiten / Good add-on with many setting options Rated 5 out of 5 stars

Dieses Add-on tut genau das was es besagt und hat dazu noch umfangreiche Einstellungsmöglichkeiten.

This add-on does what it says and it has got extensive setting options.

Gutes Add-On, funktioniert aber nicht vollständig international / Good add-on but it don't works internationally Rated 4 out of 5 stars

Ein sehr gutes Add-on zum Blockieren von Trackern und für "Masked emails". Allerdings funktionieren v.a. die Premium-Features nicht in allen Ländern. In Deutschland funktionieren zur Zeit z.B. "Masked Phones" und "Masked Cards" nicht (siehe FAQ:
Es wäre schön wenn die Unterstützung für mehr Ländern eingebaut würde.

It's a very good add-on for blocking trackers and "Masked emails", but many premium features don't work in all countries. E.g. "Masked Phones" and "Masked Cards" don't work in Germany (see FAQ:
It would be nice if the support for more countries will be added.

This review is for a previous version of the add-on (3.2.1083.1-signed). 


Sehr gutes Add-on aber es brauch bessere Firefox 29-Kompatibilität / Very good add-on but it needs better compatibility to FF 29 Rated 4 out of 5 stars

Es ist ein sehr gutes Add-On, aber leider werden die abgerundeten Tabs, die in Firefox 29 eingeführt wurden, wieder viereckig durch dieses Add-on.
Dies sollte verbessert werden.

It's a very nice add-on, but the rounded tabs (established in Firefox 29) will be made rectangular. This should be improved.

Firefox version: 29.0.1
add-on version: 23.8

McAfee Security Scan Plus detection

Unnötiges Add-On / Needless add-on Rated 1 out of 5 stars

Unabhängig davon ob man McAfee mag, verhindern dieses Add-On nur, dass die Adobe-Installer McAfee versuchen zu installieren, wenn bereits eine McAfee Software installiert ist.

This add-on only prevents Adobe installers to install McAfee software if it is already installed.
