Firefox Crashing on Account Sync

Hi there,

I've recently made the move to Windows 11, and since then I've been having loads of issues with firefox hanging and crashing. I've been able to correct the issue for about a week at a time by clearing my startup cache, but I did so incorrectly recently and it corrupted my profile, resulting in the need to create a new default one.

I'm able to launch firefox okay now, but when I try to sync my bookmarks and settings, firefox freezes every time immediately upon login. Is there a way I can sync my settings without using the firefox UI in order to circumvent the crashing issues present in the UI?
