whenever I run FireFox, he launched (opens) two sessions of the programme

I tried to uninstall and reinstall the latest version. Also deleted all of my shortcuts. Don't know what else to try.

You can check the setting of the homepage:

  • Tools > Options > general > startup: Homepage

Firefox supports several home pages separated by ' |' symbol (pipe).

You can use the SearchReset extension to reset preferences to default values.

Note that the SearchReset extension runs only once and then uninstalls automatically, so it will not appear on the page "> Firefox Add-ons" (topic: addons).

If you do not keep the changes after a reboot or have problems with preferences, see:
