I'm not familiar with the choice you were given. Perhaps it is a feature of one of your add-ons? In case one of your extensions is involved, could you try starting up again in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]]. You can restart Firefox in Safe Mode using either: * "3-bar" menu button > "?" button > Restart with Add-ons Disabled * Help menu > Restart with Add-ons Disabled Not all add-ons are disabled: Flash and other plugins still run After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset). Any difference? ---- Usually you can update your home page setting as follows: * [[Startup, home page and download settings]] * [[How to set the home page]]
