I'm not sure if this question belongs here, but here goes:
I know that that ForceField is not compatible with Firefox 4.x so am unsure if this problem is associated with that.
Whenever I go into ForceField's settings and hit the "Clear Virtual Data" button, a new Firefox profile is created, causing me to lose all my bookmarks and Firefox settings.
Even if I manually delete the newly create profile in hopes that Firefox would pick up the old one, Firefox will always create a new profile. I have even tried to copy all the files from my old Firefox profile and dump it into the new profile folder, it doesn't work.
I have been able to replicate problem this every time... Once I clear ForceField's virtual data Firefox creates a new profile and I can't get the old on back.
