Desktop AND Mobile! Rated 5 out of 5 stars
I consider this a necessity for web browsing and the latest update works with Firefox Nightly Android (haven't tested with Release version)! Awesome!
Although mobile sites don't usually have horrible advertising all over the place, many sites don't detect or serve the mobile web browsing community and this helps intercept those annoying and data-hungry ads that corrupt otherwise good design.
Now if NoScript would catch up there, too...
Rated 5 out of 5 stars
If not for this and NoScript I'd be using Safari! I worked in advertising for years and live here in NYC and we're hit with thousands of ads a day! I understand that many times it helps pay those bills, but being able to browse the web and view just about *ANY* web site without advertisements is a BLESSING!
Sure, Safari has ad-blockers... but Firefox has a whole lot more to offer.
