None of the Google webapps mentioned (Drive, Docs and Sheets) are incompatible with Firefox. What the user is seeing here isn't normal behavior and shouldn't require a switch to Chrome.

in about:config setting called network.http.referer.spoofSource was set to true, setting it to false makes the issue i described above disappear. While my issue is solved, I still don't understand why on every Firefox profile i create this setting is set to true, and whether changing it is a security concern

That's odd - it shouldn't be the default Firefox behavior.

Are you using Firefox, and not a derivative (like Tor Browser) which applies special settings for anonymity?

Have you installed any privacy / security-related extensions?

I am using standard Firefox, but yes, i recall using ffprofile.com for my settings. Guess something inside my generated profiles and preferences messed with that particular setting.
