Hello zora

my problem is different . i don't have any password issue. when i login firefox shows 500 error . but in browser i am logged in. the problem is all my bookmarks and passwords are not showing if i sync it only shows recent bookmarks which i marked after this issue.

Hi kd, glad to see you on Mozilla Support Forum.

Try to delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave). If that isn't enough then delete the prefs.js files to reset all prefs and maybe also delete the compatibility.ini file to reinitialize the profile.

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
