So sorry to hear that! Is there anything that we could help you with? Maybe you're experiencing a known problem and we'll be able to fix it!

Anyway, if you don't feel like using Firefox anymore you can remove it through Windows Control Panel.

please just describe how to get mozilla firefox off my computer for ever!

Any particular reason why as you are more limited in what browsers you can use that still supports the EOL Windows XP and gets updates.
