Why does Firefox always start up windowed instead of in fullscreen?
My installation of Firefox always starts up in windowed mode, even though I only ever use it in fullscreen. I thought that it might have been that I enabled privacy.resistFingerprinting, but that wasn't it. I also tried refreshing and then reinstalling Firefox, and that didn't work either. Could it maybe be some other setting that I might not even remember having changed? Or is my Sync account just broken?

Close Firefox. Open your file browser to this hidden location:
- Mac: *~/Library/Application Support/Firefox/Profiles
- Linux: *~/.mozilla/firefox/Profiles
- Windows: %AppData%\Mozilla\Firefox\Profiles
- *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
- Windows XP: C:\Documents and Settings\<user>\Application Data
\Mozilla\Firefox\Profiles\
Search for the above files. Then rename or delete them. Restart Firefox.
Alright, that worked, thanks! Because of how that article was phrased, I thought that refreshing Firefox also created a new profile, but apparently not. Should have read it more closely I guess :D
Glad to help. Safe Surfing.
Okay, just now I started Firefox and it opened up windowed again, and this time, deleting xulstore.json doesn't work. Do I have to refresh Firefox now? And do you know how xulstore.json becomes corrupted?
https://support.mozilla.org/en-US/kb/update-firefox-latest-version?cache=no Did you update Firefox to the latest version 66.0.4 May 5, 2019 Fixes add-on certificate issue.
Yes, I just checked and then deleted the file again (in case the update had just happened) and the issue is still there :|
Use these links to create a new profile. Use this new profile as is. Is the problem still there?

Well, after resetting / deleting / whatever my profile, reinstalling Firefox etc, I figured that my Firefox Sync account might have had something to do with it, since it always works for a while after I do one of the above, and at some point it randomly starts going windowed again. I have now done a reinstall without syncing with my previous Sync account, and so far it's worked. Let's see if it stays that way.
