The best Add-on! ᚢ ᚢ ᚢ

Sadly not actively developed, but still works amazing, I find it better than any other privacy plugin, or even than combination of them. Due to how easy it is to customize/adjust on per page basis, no deep menus or anything, click, whitelist some domains, done.

nice script and content blocker.
easy to adjust and unblock if needed. great work. Thanks

Amazing - a must have

Naprawdę działa. Super. Dziękuję

Beautiful & very useful. I hope Raymond Hill will continue updates. I think "For advanced users" should be removed in the section "About this extension" so as not to scare people into installing it without even trying to use it first.

recently tiktok wont play videos unless this extension is completely disabled. Even if you turn off the extension on it's options while browsing tiktok it still wont load and play videos. i need to go on the add-on tab and completely disable or unistall umatrix for tiktok videos start playing again.
Oh yeah i disabled add-on by add-on till i found out which one was the problem.

Phantastisch, leider habe ich kein Icon in meiner Adons-Zeile

It's a very sad day to see this addon's repo being archived and the developer abandoning the project. It's a great tool and hopefully in a not too far future development will resume! Thanks for the addon and your hard work on creating one of the best addons on Firefox.
