Computer locks up about a half an hour after launching firefox. (It's the only thing running at the time). After updating to version 10 I've ran anti-virsus, anti-malware programs CC Cleaner etc.... I know it's firefox because my AVG ant-virus program gives me a warning everytime I run it that it's using a lot of memory. What are some things I can do to fix this?

Hi caliberzzz,

You should take a look at our troubleshooting section for performance issues. There is a lot of good information in there on high CPU usaage and memory issues.

Hopefully this helps!
