I know its antithetical to Flatpak sandboxing, but I genuinely spent hours trying to move a non-Flatpak profile to flatpak and gave up. I gave the Flatpak filesystem permissions and then it would use the usual ~/.firefox folder, even if it says it doesn’t in about:profiles.

I can’t explain why any of this works the way it does but it appears that Firefox is just very confused about profiles when it exists in a Flatpak container.

Privacy wise? Probably nothing. The company engages in shitty behavior, though, and will try to upsell you even if you’re a paying costumer. I switched to Tuta because of that, and then Tuta started doing all the same bs…

The luddites were not opposed to technology

I’m surprised it has managed to stay alive for so long, in the first place.

Thank you for the write-up, it was informative!
