I blame Autofill for this - After installing that addon- yours disappeared... along with 25 client profiles and their login information.. which is NOT GOOD FOR ME AT ALL.
I removed the autofill and a bunch of other stuff for good measure... but it appears that my ability to use the profiles I've established is gone. PLEASE help with this!
I've restarted the browser multiple times.. I may try reinstalling firefox but I'm worried that could wipe out my information all together if it is still somehow recoverable...
It seems a Firefox bug. But did you fix it? If an extension is the culprit I can mark it as incompatible.
