Hello

Disable hardware acceleration

To enable hardware acceleration in the Firefox web browser do the following:

• Tap on the Alt-key on the keyboard and select Tools > Options from the menu that opens up.
• Switch to Advanced > General in the new options menu.
• Locate "Use hardware acceleration when available" and check the option.
• Restart Firefox.

Let me know how that goes

Hi again

If the issue is not solved, your problem is probably caused by an extension (in your case, this could be Adblock Plus), theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

Hardware acceleration is disabled. Using AdBlock Plus. Same problem on two different desktop PC's with same browser configuration. The Google search box won't allow me to type anything until I click in it at least one time and then I need to click again before it allows me to enter text. Seems like it's loading something in the background. Never had issues until recently. Everything else works OK.

Thanks to all that replied. Solved all problems by totally uninstalling FireFox including registry keys related to Mozilla. Downloaded fresh copy of FireFox and reinstalled after reboot. Everything is working much better. Problem solved!  ;-)
