What is the home page setting if you check the value of the browser.startup.homepage pref on the about:config page?

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

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

You can check the home page setting:

  • Tools > Options > General > Startup: Home page

Firefox supports multiple home pages separated by '|' (pipe) symbols.
