Certain tabs reload every time I start Firefox. Specifically: CoolIris; Download Helper; Getting started with Firefox; FlashGot; & NoScript. I can close the tabs before exiting, and they will reappear on restart. This has happened several times before, and each time I created a new profile and it would be 'clean' for a while, and then these tabs will reopen even though I closed them before exiting. Normal operation should be that only the tabs that were open when I exit Firefox should reappear on relaunch. An additional problem (which may not be related) is that NoScript will not save my permissions from session to session.
