Great addons for Firefox. It is light extension and fast.

just worked, uses less RAM, it's simple, the turn off button is ginormous, what I like. It doesn't refresh the tab automatically, it turns off and remembers the domain.

I love this extension, it's really useful for blocking annoying ads. I also like how it's light on system resources meaning it's good for people with old computers that have limited Memory and Limited CPU Power. I personally have 2 computers, one of them is old and the other one is a new one that's fairly powerful! I use this add-on on both computers and it works well.

Simply the best

TL;DR Regarding 'ad blockers' it's the GOAT.

I'd like to openly thank you Raymond/gorhill for taking the initative to create uMatrix/uBlock those many years ago and for your continued dedication to the development and optimization of a project that has truly made internet browsing a safer, more efficient and enjoyable experience. You've remained steadfast--both pre- and post-fork--to the origin(al) vision of transparent development, free access, and providing extensive control to the end user. I tip my hat to you, sir.

God Bless and best wishes this year to you and all the other amazing contributors behind the scenes at github, the language localisation volunteers at crowdin, and of course those who rarely receive any credit--the makers and tireless maintainers of the filter lists.

I so wish I could donate--but we all know the story on that one!

классная вещь!!!!!!!!!!!!!

Great add-on/extension and great developer. I have this extension installed on Chrome/Win, Firefox/Win and Firefox/Android. It is quite easy to import/export settings and rules between browsers or backup them. And once you learn how everything works, you can't live without it ;)
