When I sign in I always have to change password because FB won't accept the password I had with them I've been with them for years they send me to a box for phone number/email to verify my account. It says my account does not exist when I backspace there is a dialogue box that says the requested document is no available in Firefox cache. This is off and on sometimes it lets me in sometimes it does not I don't know of anything I'm doing differently to Firefox that would account for this missing document is this a problem with FB or FF or what? I've tried to find the cache and can't at least not so far and I can't find anything on the web that answers my problem about this situation so any help that would let me get into FB consistently and fix this problem would be highly appreciated. I have exactly the same problem with Edge, Chrome, Brave and whether or not I use privacy browser mode or not. Thanks for any help hope to hear from you soon.
