While the extension is discontinued, it's still very powerful and works as of the time being. It definitely is for advanced users, but it's not too hard to figure out.

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.

Someone dragged my attention to the fact that Raymond Hill got upset (see https://github.com/uBlockOrigin/uMatrix-issues/issues/291#issuecomment-694988696)
This is bad news. This extension is a niche, but very useful. The interface is clearly a UX wonderful design, given the mission it tries to fullfill.
I wish someone is willing to continue to maintain this extension. There is nothing to add currently, but from time to time, there's always something cool to add or fix.

A big thank you to Raymond Hill for supporting a better Web experience, and all people that thought uMatrix was broking their browsing experience when it was the opposite.
