Hello so i've recently wanted to start using firefox as my browser but every time i try to open firefox the window where its supposed to be appears for a few milliseconds then just dissapears like it never opened before

I am on windows 11 and I am up to date with updates i have updated my gpu aswell

Note: I've reinstalled firefox multiple times at this point and have also fully reset my pc 2 times so far to no avail I am also using normal windows defender and nothing changes when i try to turn it off for example its still broken. My firefox does open when i run windows in safe mode but it stop working when i switch back to a normal windows profile I cant even run firefox in troubleshoot mode because that window to open it in troubleshoot mode dissapears after a few milliseconds aswell any help would be appreciated ive looked at numerous pages about troubleshooting firefox and it just hasnt helped at all.

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

See "Visual Studio 2015, 2017, 2019, and 2022":

You may also have to install the Visual Studio 2013 Redistributable Package. You need to reboot the computer.

Im now even more confused as firefox works perfectly when i launch my windows 11 in safe mode but i do not have internet as i do not have ethernet connected to my pc so i cannot do anything whilst in safe mode
