Firefox won’t open. It worked yesterday. I’ve tried everything.
I’m on a windows 10 dell Inspiron 7790 aio. When I click on the browser icon, the cursor buffers a little bit and then nothing happens. I’ve tried uninstalling and reinstalling, restarting my computer, going into profile manager and creating a new profile, and deleting all Firefox files from my computer. I don’t know what to do. Thank you.

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.
Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.
