Hello, I am using Firefox for developer since some time. I enabled the "clear history when firefox closes" option . I selected in the settings to clear only browse and download history. When I close firefox and start it again, it signs out automatically. I have to sign in every time I launch firefox. This is very boring. Then there is another problem. When my account is synced, firefox sync the settings related to my account but it should not. In the sync settings tab, I have not checked the "options" box to sync. Why is firefox doing this ? I have another PC where firefox remember history so when my "normal" PC syncs (I repeat : it should not), the history settings go back to remeber history and it is so boring to do all this stuff when firefox start... Help ! Thanks
