AdBlock was one of the first things I installed on my n900. I set it up with easylist+easyelement just as I do in the Firefox plugin version (gui/web), rebooted twice, and it has been invaluable. It has worked smoothly for the last month. For the record, I did not hack any of it's pref files. (Same story with my n810 two years ago.)

Best thing I can suggest is that if you are having weird problems is to reflash and wipe the relevant pref files.

I am sorry to hear that a few folks are having issues, but I find the repeated calls from one individual to have it removed from extras to be extreme.

Thanks zerojay! (Sorry to hear about your dead n900.)
