It doesn't "still work" if you're on Firefox. uMatrix has bugs that cause it to randomly delete your cookies, or occasionally fail to block a request (race condition? Looking at logger shows an incorrect domain on some requests)
There are community-made forks which fix the cookies problem, like nuTensor.

Not my experience at all. I run uMatrix on every computer I have and it is awesome. Still annoyed it was replaced by uBo which is quite good, but nowhere as nice as uMatrix. Luckily uMatrix still works great.
I wish they'd just scrap the uBo interface and replace it with the uMatrix interface which is far superior.

Thanks, I'll check nuTensor. I'm using uMatrix with Firefox on both Linux and Android and I didn't notice anything strange but maybe some of those bugs were hidden under the normal hiccups of finding the right combination of rows with trial and errors.
