Please update to the current Firefox 22.0 release.

  • Help > About Firefox

The Firefox 19 version that you currently run is no longer supported with security updates.

  • It is important to update Firefox and add-ons to the latest version to get all security fixes.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.
