It literally took me less than ten minutes to set up firefox. I carried all my bookmarks and passwords from edge and set up a mozilla account and everything is synced across linux, windows and android.
The only thing I'm worried of, is if some websites require chrome to work, as was the case with some government sites that only worked with internet explorer in the old days.
(Does anyone know if the default user agent is chrome? I used to log in a local streaming site from edge and it wouldn't work, as it required chrome, but I used an extension to take care of the user agent. On firefox it works no problem.)
Now this is giving me splinter cell vibes. I hope the CIA is not missing any agents in the area.
