After 5 minutes of inactivity, Firefox 4 doesn't respond to my keystrokes. I just upgraded from 3.6 and I never had a problem before. What do I do?

Recently, upgraded from 3.6 to 4; now, Firefox stops responding to my keystrokes after 5 minutes of inactivity. The tab says connecting, but it doesn't register my keystrokes and nothing happens. I try to quit, but it doesn't quit, one screen disappears and another blank firefox page appears as if it's always been there. I then have to "force quit" and the program works again when I restart it. 5 minutes of inactivity and it starts all over again.

Make sure that you do not run Firefox in permanent Private Browsing mode.
*https://support.mozilla.com/kb/Private+Browsing
To see all History and Cookie settings, choose:
*Tools > Options > Privacy, choose the setting <b>Firefox will: Use custom settings for history</b>
*Deselect: [ ] "Always use private browsing mode"
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
