my firefox is blocking some websites

[fairyrak]

google.com, bing.com, facebook.com, yahoo.com are blocked on my firefox but not on chrome

what can I do? I can access everything on my chrome, but not on facebook or internet explorer

I already used avast, malwarebytes, and now I have eset nod, and now there are no more virus or trojans or spyware it seems

I guess that some other major websites are blocked, while I can perfectly access mlb.com and altavista and minor sites

Try an 'on top' reinstallation of Firefox.
(i.e. download it again and install it WITHOUT first uninstalling).

I already erased and reinstalled it. By the way, my country don't block any websites

and erasing and reinstalling it didn't work either

I already solved the problem, the cause was very strange (ipv6)
