Hi,
I'm trying to figure out how gmail keeps track of my signed in status. eg. if another site offers the option 'Sign in with Google' I enter my gmail credentials to get access to another site, if I then open Gmail in another tab it goes straight to my inbox (no credentials required) so it is clearly keeping track of the fact that I already logged in (albeit on another site). So, I'm trying to figure out how Google keeps track of my signed-in status ? I would have assumed it was via a cookie. So I go to Firefox -> preferences -> Privacy & Security -> Clear Data.
After this Firefox lists:
Cookies and Site Data (0 bytes)
Cached website content (0 bytes)
Yet if I open gmail in a new tab I'm still getting straight through to my inbox, no credentials required. So, how is Google doing this ? It's highly undesirable and very creepy. Or does this suggest a bug in Firefox (that its not actually clearing data as it should) ? I'm using version 87.0 on Ubuntu 18.04 LTS.
Thanks,
Usjes
