i wan't firefox uninstalled

This is a Windows issue

Use Settings and look for Apps etc.

Note that if you are indeed using the old EOL Windows 7 then there is really no other web browser that is still updated and supports the EOL Windows 7, 8, 8.1. https://support.mozilla.org/en-US/kb/firefox-users-windows-7-8-and-81-moving-extended-support

Chrome/Chromium based browsers dropped support of Windows 7, 8, 8.1 way back in Jan/Feb of 2023.

The only way you can use a newer web browser whether it be Firefox or another is to either use Windows 10, 11 or replace Windows 7 or dual boot a current Linux distro with Win7.
