It's buggy, crashes/slows things down, but what I dislike the most is its complete lack of support for customization. Really, if I can't make adjustments (without basically hacking it that is) then I don't want it.
I find it irritating that an ad blocker is showing me an ad for ghostery plus every time I open firefox. I acknowledge the existence of ghostery plus, I do not wish to have it, can you stop spamming me?
Really nice approach! Thanks for this! Unfortunately it slows down Firefox quite heavy so it's barely usable in combination. Loading time of pages is doubled or more as well as smooth scrolling isn't possible on loaded pages.
Ghostery has started to hide reCaptcha check boxes. Other than that, it seemed to work nicely, but that changed it from nice to annoying, especially since you won't even know that there's one that's supposed to be there to be checked! Deleted.
UPDATE: Ghostery said the problem was fixed. It has lessened, but it is not fixed. Too bad they don't know how to do a whitelist. Deleted again.
