Comment 5 for bug 136619

Adblock hasn't been touched for at least two years. The devs disappeared. Adblock is full of bugs (e.g. http://aasted.org/adblock/viewtopic.php?t=3056 ) and contains even some serious security issues (e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=338114 ). It is not recommendable to use Adblock. I don't know who has been so starry-eyed to include it into Ubuntu...

Get Adblock Plus from the official Addons-Mozilla site, it is faster, more secure and more user-friendly: https://addons.mozilla.org/de/firefox/addon/1865

I hope someone in charge updates the package soon.
