Have the same problem, tried all of this, my settings were already set to those. So still have the problem. Very annoying, considering ditching browser.

I'm having the same problem too. I have my settings set to where things should be remembered and cookies should not be getting cleared. But i am getting logged out of all websites I stay logged into. This started for me in October after one of the updates. I am having the same problem on both of my computers, one with windows 10 and one with windows 7. Firefox appears to be clearing cookies because even though I don't stay logged into ebay due to having two accounts, my search settings in ebay keep getting cleared too, just as they were if I had cleared the cookies myself. And my settings are set to where cookies should not be cleared. Please get this fixed.

Did you read the solution (above)?

Profile data can be removed or not recorded in several ways;

• 1) Running Firefox in Private Mode (nothing is recorded)
• 2) Privacy settings; (In the address bar, type about:preferences#privacy<enter>)
• 3) Many disk cleaners and anti-virus type programs can remove data from browsers
  Open their settings and have them leave the browsers alone.
• 4) Mal-ware.
