I Reset Firefox because it was slow and I was getting many 'not responding' freeze ups. It worked and my system is much faster now. I reinstalled adblocker and send to mail and changed the theme back to light from the default. I also changed the security setting to Save Logins. Today I find that all my saved logins are no longer there but I put that down to the Reset and decided it was probably time I set up new passwords. I have entered password reset a couple of sites and said yes to save the login when the pop up window appears. When I returned to the sites later to login it had not remembered the logins. When I check the Saved Logins there is nothing saved. Have I missed a setting or is there a problem.
