windows 10 – Getting logged out of Google and Reddit after a few weeks for no reason

First of all, I’m using the latest Firefox on the latest Windows 10, and I have 2FA turned on for my accounts that’s why it’s a pain to log back in every time. Also, the problem only occurs on Google and Reddit websites.

The problem still persists even after:

  • using ipconfig commands to reset and renew
  • resetting Winsock
  • reinstalling Firefox (and also deleting leftover profile data and other files)
  • scanning with AdwCleaner, Malwarebytes and Windows Defender (no threats found with any of them)
  • verifying Windows system files
  • verifying disk files

If someone could help me identify what’s causing the problem, that would be great.
