One small issue, other then that it's all good.

Tout simplement indispensable à la navigation. C'est la première extension que j'installe à chaque fois. Devrais être installer de base sur n'importe quel navigateur.

There is simply no better adblock addon for Firefox.

excellent!

uBlock blocks nearly every ad just about every time, and the very extremely few that do sneak by are so sneaky that they are fairly unobtrusive to your web viewing experience. Also, I'm a big proponent of the open source software model, and love the fact that uBlock, unlike many of the other ad blocking software out there, is FOSS.

Excellent add-on, thank you!
After many years with ad-block, I decided to try ublock. It's much more efficient, settings are not lost like in ad-block, and its blocking process can be customized efficiently.

El add-on es muy bueno, pero en las ultimas actualizaciones de Firefox causa problemas generando constantes reinicios del navegador inclusibe recien iniciado esté, se procedio a la revicion del navegador basandome en el foro de firefox, y al realizar la revision de cada uno de los add-on´s se llego a la conclucion de que esté era el que causaba el problema.

I felt obliged to edit part of my review from earlier on 10/28.

Re: uBlock Origin 1.14.16 and NoScript 5.1.2 / 5.1.3 now seem to work in Tor Browser.
It took several "removes" - uninstalls / reinstalls of NoScript before both addons worked in Tor Browser.
Finally had to remove most NS about:config or prefs.js entries left after uninstalling.

NoScript's remnant prefs "shouldn't" have bothered uBo, but apparently did.
That's the only thing different on the *LAST* uninstall / reinstall, when uBo and NoScript finally worked. No settings changes were made in either addon.

FWIW, NoScript and uBo did fine on my 2 machines, until the last few days. They both had updates in Oct '17, so one or both created an issue for the other.
Side: It's goofy not to be able to edit a recent review vs. forced to give another star rating.

Gut
