On sunday evening, Mozilla/Firefox for my Windows Vista application prompted an upgrade to Firefox 6, and also prompted an upgrade of the Adobe flash player. After downloading both, photos I had just downloaded from a camera card were rendered useless - a dell wrench replaced the images. I then reset the system to the last windows update of August 19th, to eliminate the possibility of any other errors the upgrades had apparently caused. And now, I click on the firefox logo on my desktop shortcut, and can not access firefox browser. I do not care for the internet explorer as a browser.
