Firefox 4 become not responding after every few minutes ( mainly 10 minutes). And it came back to its normal state within 10-15 seconds. I reinstall windows and Firefox, but same problem occur. On using chrome 11 and IE 9 I have no problem. I also check that there is no problem on using Firefox 3.

I mainly use Firefox for my web browsing, but due to Firefox 4 I totally disappointed. What should I do for now?

You have an add-on installed called Internet Download Manager. It's on Mozilla's Add-on Blocklist @ https://www.mozilla.com/en-US/blocklist/ at the foot of the page.

Uninstall it by clicking the orange Firefox button, go to Add-ons and then remove it in the Extensions menu.

If the problem persists, try running Firefox in Diagnose Firefox issues using Troubleshoot Mode. If it functions properly in that configuration, then one of your other add-ons is the culprit.

The version of IDM that is installed (version 7.2.8) is not on the blocklist, there is no need to uninstall it. It is versions 6.9.8 or earlier that are blocked.

Firefox may be doing some maintenance with places.sqlite or other files.

Also make sure that other (security) software isn't locking files in the Firefox Profile Folder
