OK ... Windows 7 installed an update earlier today (KB2952664) which played havoc with the system (reset startup settings etc in WIndows) then when I fired up Firefox all of my settings had gone including Bookmarks and add ons etc. When I managed to startup Firefox and then tried to restore the bookmarks from the .json file or from the HTML file Firefox hangs and I get a warning/message about the script being busy and do I want to wait ???? And there it sits, doing apparently nothing with the 'busy' mouse pointer scrolling away ... so after an hour I gave up and despite rebooting etc etc (even created a new profile) the darn thing just will not restore the bookmarks !!! Any assistance would be most helpful ... pleasssssssssssssssssssssssssssssse Thanks
