I always fear that installing the updates is going to damage my current installation when I get the pop-up window. It always tells me that a number of things are incompatible after I carry out the installaton so they do not work anylonger. This time I am sure that the last time I installed an update, Firefox lost me a number of folders with bookmarks. I have tried restoring the previous savings of bookmarks but the lost folders are not there as far as it saves the previous bookmarks ( I think it is only 1 week). I believe they were within one of those folders by Firefox like "Bookmarks toolbar" So WHERE the hell are the folders? I also have synchronisation for my iPAD but the bookmarks are not there either. Has bloody Firefox deleted the folders from its sync website?
