Excellent add-on: it allows me to enable only what is needed to get a site working, without permitting cookies and add-ins from the dozens of 3d-party sites whose content is often incorporated into modern websites. Yesterday (2021-JUL-25) it broke Firefox's Internet access completely, but updating to v1.4.4 fixed the problem.

It works perfectly!

uMatrix unexpectedly came back from the dead! Its dev has luckily changed his mind, hurray!

Thanks for the fix for the security vulnerability!

Must be updated... :)

Rest In Peace.

some rules/lists in the assets tab have been outdated for a while and update button isn't doing anything with them

this was the gold slandered here. i tried again today to use ublock origin with no luck. this was probably my 10th attempt at liking that software over the last year or so but i simply hate it. i return to umatrix within hours every time. so im gonna go all windows xp with umatrix and use it till it simply no longer functions or just maybe someone else can pick up where Raymond left off because ublock simply isn't an option for me!!

It's support was ended 2 years ago but it still works perfectly and feels complete enough that I don't feel like it necessary to move on to something else. I have yet to find a plugin with an interface as good as uMatrix has.
