I have recently updated to version 81.0.2 of Firefox, and have noticed that for some reason, twitter will randomly sign me out for no reason even if I don't sign out of the site when I close the tab, forcing me to sign back in every so often. Curiously, something similar happens with gmail, as it will make me sign in both of my email accounts, even though normally when I bring up the gmail website it usually just asks which account I wish to sign in to. I have not cleared my cookies in the last few days, nor my cache, so this shouldn't be happening. What exactly is happening here? I didn't have this problem in the previous version of Firefox. Can anyone help?
