Rated 5 out of 5
by Firefox user 13541785, 8 years agoI like uBO because you can set it and forget it, or you can dive pretty deep into the stack for fine tuning with its Dynamic Filtering mode. It's also one of the few extensions I can run across all the browsers on the different operating systems I use day to day. If you're a developer, this is the blocker to use.

- Rated 5 out of 5by Brandon, 2 days agoA MUST HAVE extension!!!! I can't tell you how many times I have run across websites either full of ads (all of them require a ad-free subscription) and unbearable to be on. With this extension, I don't have to worry about ads, scammers, etc anymore. Hell, this is great if you want to block those pesky 30-minute ads in YT videos too. Just an overall great open-source extension and it's sad that this is still needed in the year 2026.

- Rated 1 out of 5by Firefox user 18183488, 5 days agoYes it blocks ads but YouTube knows you are using it and forces a delay as long or longer than the ad it blocks
