|Go here from Firefox and you will see the Flash Player version you have installed and a table listing what you should have (you are out of date):|
Just above the table in the writing it shows "Player Download Center" in blue. Click that and install (Run) the latest version. Be sure to uncheck any optional offer before downloading. This could fix your flash issues because the update replaces it.
You should also go to the link again from any other browser you have (such as Internet Explorer and Chrome) and do exactly the same.
If you do factory restore you will lose everything you have put on since - best avoided so try the above first. You still have the option to do the restore if that, or anything else suggested, doesn't help.
Always pop back and let us know the outcome - thanks
