After using Firefox as my default browser with no issues now for at least 6-8 years, suddenly within the past 90 days I am being signed out of Firefox without my knowledge or consent almost every day. Thus, websites are not recognizing me that always did prior to these issues (Facebook, Amazon, local grocery store chains, etc.) and I am having to go thru full security log in procedures over and over again, day after day. In the past I NEVER had these issues unless I ran a CC Cleaner scan or other PC clean-up software and, even then, I would simply go thru the security procedures and sign in to their site or account one time, then would be fine for week/months until I ran a cleaner scan again. What do I need to do to keep myself signed in ongoing with Firefox so that it does not disconnect me every day and I can avoid so much wasted time with all these security measures for my commonly visited sites (incl YouTube)? If this continues I am strongly considering using a different default browser that hopefully can eliminate these very irritating daily issues. Thanks for your help, Jim S.
