I wanted to install the Google toolbar extension, so I installed Add-on Compatibility Reporter 0.9.2. Then I installed the Google toolbar extension. When I restarted my computer I got this message. The Google toolbar did not work, so I disabled it thinking that would correct the problem. How can I get back the ability to print webpages. Thanks

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode 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).
