I am aware, thanks to this thread ( https://support.mozilla.com/en-US/forum/1/381229 ), that Firefox doesn't save sessions when browsing history is cleared at close, as effectively the open tabs are themselves cleared from the history before the session is saved. But I would like Firefox to behave differently. Is there any way to change Firefox's behavior so it will clear my browsing history when it closes, but remember only that a certain list of tabs were open, and then restore those tabs when it opens (not even necessarily with those tabs' histories)? I'm running FF 3.5.6 on Mac OS X 10.5. Thanks.
