Choice in preferences not getting stored

[ghost]

I tried to check the option "until firefox is restarted" in preferences > remember insecure sites (and clicked the save button), but on restart the checkbox is reverted to "for 7 days".

This issue should be looked into, it is getting annoying (I visit two dozens of http intranet sites and I am constantly manually reverting back to HTTP each week), but in all fairness, you can type in e.g. 9999 days and it does save it.
