basically my gf was on her macbook and was browsing away happily but then she got 3 popups, when she went to close the pop ups she managed to close 2 of them no problem. the other one (for an MP3 site) however doesnt seem to want to close. so i told her to force quit firefox and it should go. she managed to force quit firefox and the pop up disappeared. so she re started firefox again and it asked if she wanted to restore previous session or start a new, so obv she clicked now, however it didnt start a new session it reverted back to the old one and had the pop up there still. she then completly deleted firefox from her macbook and restarted her mac and re installed firefox only for it to do the same thing once again. i dunno what to do. any help would be appreciated
