when playing most games, ( particularily in facebook ) the computer freezes. Nothing works, have to manually restart. How can l fix this.
Windows 7, Firefox 18, Flash and Java up to date. Any other web page l visit, no issues. Firefox works very well elsewhere, but computer freezes in facebook games, periodically. NOT all the the time, but has happened at least 5 times in last 4 days, Nothing will ' unfreeze ' it that l have tried, so manually shut computer down, then restart. When computer starts, normally, l can return to page in facebook l was on, and resume, often with no further issues. Firefox is my main and trusted browser. Some programs from IE 9 are still used as well on this computer. l wonder if there are any other plug ins l can install with firefox that would help.
