How much can some browser tabs actually spy on what's going on in other browser tabs?
Non-techie here, and because I was never sure, I just used different browsers for different things. But I'm getting tired of being autistic and just want to use Firefox for everything and be done with it.
So lets say I'm logged into my main personal Google account, with Gmail and Calendar open in tabs. Then in a new tab I go to xvideos and browse a few vids, finally settle on one, then have my fap. To what extent could Google (and any other tabs open) track my fapping session and habits?

A lot. If you're concerned about being watched, always run things in Private Browsing and only do one thing at a time. Completely close the browser and reopen before you switch to the next thing.
