@Blockchainruless,
Hmm interesting – it could be the Privacy Pass extension but I think it’s unlikely.
So when you say
Do you mean it signed you out of 3-4 Google sites? Or do you have 3-4 different Google accounts? My assumption has been you’re referring to different sites using the same account.
Either way, I would be curious to see if you get this same behavior when you’re using a new/fresh browsing profile. The only problem there is that you’re saying that it’s hard to tell when the issue will occur, so it may take a while to run that test. However, if you’re willing to it would be a great indicator of what’s going on.
Create a new/temporary browser profile, browse normally for a while and see if the issue shows up when using the new profile.
