I am using Firefox 7.0.1 on Windows 7. I always have at least 3 tabs open: Yahoo Mail, eBay, and PayPal; I also usually have Facebook and Twitter open, I have tired closing each tab individually to figure out if it was the website causing the issue and the issue still occurs. . I researched my problem for about an hour and found many people having similar problems. I think my Firefox is 'hanging' as mentioned here: https://support.mozilla.com/en-US/kb/Firefox%20hangs. Unfortunately the few things I have tried have not solved my problem. I ran Firefox in safe mode with all plug-ins disabled and the problem still occurred. I checked to see if if it was the CPU usage, my computer normally uses 1-2% for normal browsing but when Firefox freezes it jumps up to 12%. These freezes occur even when Firefox is idle. For example, I am currently using Chrome to tell you about my problem and Firefox just froze for about 45 seconds. These freezes occur roughly every 5 minutes, sometimes less some times more. I am not using an AVG toolbar and my browser is not set on compatibility mode. Please let me know what there is I can do to solve this as Chrome and IE are not suitable for how I work.
