Hello. I installed Linux Mint on a new desktop that I built about a week ago, and I'm starting to get used to it, so it's probably time to start using it for some actual life things.

A couple of these do involve talking with family members all in Facebook Messenger, as well as the necessity of using Google Workspace for some work-related functions.

I'm aware that using both of these is a compromise of privacy in and of itself, but I'm still interested in mitigating the damages best as I can.

What steps can I take to make the usage of these as private and non-invasive as possible? If it helps at all, the browser I'm using is Firefox and the operating system is Linux Mint.
