I am constantly being signed out of Firefox Sync on my desktop.

I just switched over to Firefox from Chrome about a month or two ago across all of my devices. I have them all synced to the same account so that I can easily move between devices (desktop, Android phone, iPad). However, my desktop frequently signs me out of Firefox sync and makes me sign back in. When I do so, all of my UI modifications and some of my settings are reset and I need to reapply them. It's getting pretty annoying. I've looked at some other threads (like this one: https://support.mozilla.org/en-US/questions/1227940) but it did not solve my problem. Any ideas?

Back up and restore information in Firefox profiles.{web link} I use an add-on that makes backups of my user profile, Just In Case. Unfortunately, it is not compatible with the current Firefox.

Every now and then, open the profile folder and create a copy of the current profile as is to another location on your hard drive. This way you will have a backup.

If you do this each day, you will not lose much data. This should be done with Firefox Closed.

Note: In case you need to restore from these backups, you may need to overwrite old or corrupted files.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
