Firefox hangs frequently, freezes and says "not responding", then starts working again. Have tried suggestions under help to no avail. Ideas?

Running the latest version of Firefox on my laptop (windows 7-64bit) and Firefox hangs periodically at random times. Screen greys out, CPU usage spikes, and then resumes working. Cycle lasts between 10-30 seconds. I've tried the suggestions under "Firefox hangs randomly" to no avail.

See:

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.

Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.

Tried all of the above, Firefox still freezes fairly frequently.

I had this same problem... I've un-installed(Control Panel\Programs and Features) all JAVA's(sort by name) and loaded JAVA 6.0. Firefox is back to normal again... (remember to change the settings in JAVA to not check for updates...) Hope this helps!
