10-3-21: near perfect with a few minor flaws: ran across tiny social widgets that cannot be nuked. Try to nuke them with either lightning or pen, works for one time only than come back again. webpages are getting smarter in how to stop u block. Also cannot find a link in the extension to send input to developers whereas before there was such a link to report instances where the program did not work.

One of the VERY FEW addons that is really good and works well. Easy to block objectionable images on webpages so as to deny them ad revenue, like with sites that mistreat users. Only criticism I have is that when using an encrypted connection like with a vpn or tor, the settings do not stay and you have to reset the blocks. I'm guessing its because the ips and other stuff changes with tor so cannot make the blocks permanent. Great extension over all. Look for other add-ons by this author they will be good.

Very convenient to remove trashes like localized ads , banners and things I don't want to see in my eyes .

I wish the setting would be like Adguard . Because I have to block shits every time I access .

very good

One of the better ad and nonsense blockers. However this morning started blocking me from logging in to my banking site. Had to list it as trusted. Why so many block lists? Makes debugging almost impossible for me. I am running 1.31.0 on Firefox in Linux Debian Sid.

Until end of November 2020 all works. Now it does not work, it hinders now to work properly with Apple's iCloud.com (login prompt to verify) and banks' websites (login process) .

Firefox will take too long till ublock resolves DNS, this leads to endless loading to websites till plugin is disabled and reenabled

So far, so good! Keep it up uBO!
