This time my Firefox opens random websites every now and then, sites about "vacations, or exotic places" pretty random, advertising maybe.
I tried uninstalling and Cclreaner nothing worked.
Any ideas?

You have spyware/adware installed. Use SUPERAntiSpyware and MalwareBytes Anti-Malware

Thanks I'll try them and tell you what happens, and there's another little problem and I don't want to make another topic for it. when I reinstalled Firefox the spell check feature doesn't work on the new one, I disabled then enabled it again from the firefox options but still doesn't work.

Ensure that this option is checked in the right-click menu (might have to right click on text):

Also check the languages to make sure English is installed and selected (if it isn't, click on Add Dictionary and you'll be redirected to the Add-Ons site with a list that has English (US) and others).

Thanks neo, spell checking works fine right now, it appears that I had no languages in the firefox dictionary when I reinstalled it. And the random pages problem is gone for now after I scanned the PC using MalwareBytes Anti-Malware, thanks a lot neo, you're the best!
