As a rule, I have my browser set up to clear ALL data when Firefox closes. I do not want Firefox to remember Site Preferences or Passwords. Recently I signed up for Firefox Sync. A useful feature that I would like to continue using. However, in order for it to work, I have to allow Firefox to remember Site Preferences and Passwords. Now, every time I go to a site that needs a password, I get the pop-up asking if I want to remember the password and have to choose no. I realize eventually I will have said no to all my common sites requiring passwords, but this gets tedious as I use multiple computers with the same browser settings. What I would like to know is, can I set up my browser to clear ALL data but somehow create an exception for Firefox Sync? That's the ONLY reason I need to remember Site Preferences and Password since the feature won't work otherwise. Many thanks for the help.
