I had two Firefox windows open, one private and one not, and a lot of tabs open on both, and while I was browsing the internet on the non-private tab, suddenly both of them close. I reopen Firefox (or it reopens itself, I don't quite remember) and it shows me a message telling me about how I can save articles on pocket to read them later instead of keeping lots of tabs open. I restore my session, and most (but, bizarrely, not all) of my tabs come back, but then, I try to log into gmail, and I never get past the stage where it asks me my email adress, I keep re-entering my email and clicking on the next button and it just loads the same page again, and when I try to log into crunchyroll it brings me to a page that just keeps loading and stays black without ever being truly loaded, and when I try to log into twitter everything stays black too except with a twitter logo in the center. I can still go to some other sites on Firefox, and I can still go to twitter, gmail, youtube and crunchyroll on Google Chrome, but twitter, gmail, YouTube and Crunchyroll don't seem to work on FireFox and I don't understand why!
