new version comes up with box that freezes firefox had to uninstall
I open firefox and the home page comes up. A small box comes up that has a box to check, but no way to get rid of it. I can't exit or do anything. Have to go to task manager to get out. I uninstalled and reinstalled. Same problem. Had to uninstall. Your program has a bug or virius in it.

If you decide you want to use Firefox again:
Make sure to use the official download site. You can save a full installer from this page (scroll down to your preferred language): https://www.mozilla.org/firefox/all/
Also, could you try starting Firefox in its Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.
When Firefox is not running, you can start in Safe Mode by holding down the Shift key when double-clicking the Firefox icon/shortcut.
A small dialog should appear. Click "Start in Safe Mode" (not Reset).
This may or may not resolve the home page issue, but should narrow down the possible issues.
