works nicely. it doesn't slow Firefox. nice extension for Firefox with Ubuntu.

Excellent

This extension supports enough stability and hides almost all of ads

Must have

Nice add-on for Mozilla.

AdBlocker Ultimate has been used in our household for a long time. We also have used it's cousin, ABP. Anyway, as a cybersecurity professional, I hate annoying and intrusive ads. I want to load the site, do what I came for and leave. There is a time and place for ads so the feature to allow them on certain sites is welcome and appreciated. This has a 12 out of 10 rating. Meaning you need this extension and should support it once in a while with a little cash injection. Show the developers some love!

All are ok!

Great!!!
