MUST HAVE BROWSER ADD-ON!

Seriously, this add-on is amazing. It's the swiss army knife of Firefox add-ons. It blocks ads, trackers, malware, spam, scams, annoyances, etc. You can configure it to do whatever you want, whether you are an advanced user, or if you're just a basic user, the default options will do fine.

It's easily the best ad blocker and content blocker overall that I've used. It's easy on resources, super easy to turn on and off, and gets the job done. I think everyone should have this extension honestly. Once you get it, there's no going back.

The Best

7-10-25: cannot deal with this little square social media widgets-takes too much time to delete them. Slow to load
author needs to find a way to IDENTIFY WHICH block to use for any given crap ad. It's too slow. Need a method to select all adds you want to block at once. Except that it's slow good addon

3-27-25: too damn slow.
aug. 2024: Getting worse by the minute: slow to load slow to mark offending images, many sites are immune or very difficult to block. Not as good as it once was. Sites have gotten clever in making it not work or making it more work to block them than is worth it. It's slow to load and filters slow to activate. Still no easy way to report sites that do not work with it. You have to block like 10 different widgets to get rid of one on social media sites. To hard to block multiple ads at one time.
5-19-24: has deteriorated in last year or so. SLOW to load, Slow to delete ads you have defined. Sites are working around it making it not worth the time to delete the ads using it. Still have not found a better one, so can't complain too much
1-28-24; All good things eventually deteriorate and ublock origin is no exception. too slow to respond to browser callups, cannot deal with ads that repeat and keep changing, no easy way to report pages that don't work SLOWWWW. Downgraded to 2 stars
1-5-24 -really starting to get SLOWWW and a PITA. Difficulty marking items you want nuked. Wasn't able to get it to work with disk files, only online. You can tell some of the websites are desiging their pages such that ublock doesn't work or works inefficiently requiring more time to get rid of their garbage than is worth it. Popup slow to appear. Still a good extension but has gotten worse not better.
9-22: one of the VERY FEW addons that actually works and is not a PITA. Congratulations there ARE some good programmers out there.
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.
