It appears that creating a clean profile stops the browser from crashing. But - as far as I can tell - it is not possible syncing user data even from a recent version of FF.

The problem is only related to syncing passwords, everything else can be synced.

[George K (koge10445)]

Indeed. Removing passwords sync under Sync Settings does seem to stop Firefox from crashing. This is the recommended stop gap solution until a proper solution appears.

I tried disabling password sync but this did not work, then disabled other sync options. In the end I had to sign out of Mozilla and disable all synchronisation just to get Firefox to stop crashing, not ideal.
