I haven't changed yet, and i don't plan to, unless i see a fork of adblock plus bringing back the old functionality, because that is for me the biggest problem with adblock plus right now.
The acceptable ads is the problem, since you cannot block it in any way through adblock anymore, the block and console features are both seriously useless, and the custom filters do not seem to work when you add expressions or wildcards directly to the list (does not get saved, only through the block console it saves, but you cant use wildcards there so again... useless), something which worked flawlessly through the old ui!
So i started to monitor traffic and add everything to my host file instead, which will probably turn out for the better in the long run, allthough you cannot do everything that adblock does through the hosts file.
For information, in 14 days i have gone from 20 entries, to 5800 entries in my host file, blocking both control/rotation servers, trackers, and the ad networks themselves that are not blocked with Adblock Plus, which are a plenty!! allthough most of them are easily blocked with entries for the rotation server, eg you do not need to add the 1000s of domains that these rotation servers push you to.
This is despite me subscribing to all the following filters + having a really extensive custom list from before the switch to webext.
Adblock Warning Removal List
Fanboy's Social Blocking List
Prebake - Filter Obtrusive Cookie Notices
The switch to webext killed Adblock Plus for me, and many others, and even allthough i did not really like ublock from my initial test, i have and will be looking occasionally for new and better alternatives, unless the blocking features return to adblock plus.
That was the whole foundation for adblock plus on firefox atleast. on Chrome i got Ublock, since adblock for Chrome has always been useless for my needs.
