First of all, dont give me generic bullshit answer... I know how to delete history and cookies and chace and all that crap. Problem is, recently when firefox updated, i cant delete history without it crashing. And after that history is deleted but only in history tab... On action bar you can clearly see all sites when u start typing. And delete button dont work.. I tried googling that problem but you answer the same generic bullcrap to everyone. Once firefox was, hands down, best browser out there... now is shitty as hell, its in the level of fucking internet explorer. I dont really hope for solution, but i figured i shoud give it a try.
