Facebook won't let me change password because it doesn't recognize my device (Firefox).

Hi doug,

You may want to try loggin in from Private Browsing mode and see if it helps. If the problem is related to data breach, though, I'm afriad that would be outside of our control and we can't help with that.

Thanks. The problem is not related to the data breach. Facebook just never recognizes me from login to login. Maybe to much privacy with Firefox? My current approach is to use Safari without any privacy options and to use Safari only on Facebook. I'll try that for awhile and if doesn't work try private browsing mode.

Is it possible that you set your Firefox to never remember history when you close the browser?

Can you check about:preferences -> Privacy & security -> History and check what you have there?

that was the case initially but I tried making an exception for Facebook cookies. That didn’t work. when I use Safari now it often does not log me out. I can go back the next day and not have to login again. So something is different

My safari approach worked. Facebook probably tries a lot of ways to track me that FF interfers with. Whatever, now that I’ve updated the risky password I can go back to using FF like before. Thanks for your comments.

It makes sense if you don't set Safari the same way as using Firefox. If you want Firefox to remember your login state when you restart the browser, there's no other way than using web cookies.
