When I open Firefox I get a message that says something about a script not working on the page... Script: resource:///components/nsBlocklistService.js:756 and do I want to continue. Does anyone know what this is?

Surely a broken add-on or script. Restsart Firefox in safe mode and check if the issue is still here. If it's not present, find the culprit add-on.

That is the JavaScript that deals with block listing in Firefox.
This line seems to be about testing for blocked plugins.

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).
