Now as everybody could notice until now, Firefox at some point has a problem with keeping you logged into certain sites, if not ALL of them.
I’m sure that most of you already experienced something like this. Starting firefox only to see that you’re not logged into the respective site. I know I had trouble with staying logged into youtube, and some other forums I generally browse.
Even my gmail account was no exception. I tried everything. Clearing my cache, removing the cookies manually for those respective sites, but after I restarted firefox the problem remained the same. Firefox simply could Not remember my login/password data.
This is because at some point the file in which Firefox stores it’s cookies gets coughed up and can’t store anymore data. So to fix this the steps are simple.
1. Close Firefox
2. Go to Start -> Run and type in %appdata%\Mozilla\Firefox\Profiles\
3. Open the folder that appears (there should be only one folder)
4. Either delete the file named cookies.sqlite or rename it to cookies.tmp
5. Restart Firefox, and everything should be fine for now (You will have to re-type in your login data)….that is until the next time Firefox decided to pull this stunt again.
