Firefox opens but doesn't load any sort of web page
I just got a new computer, and Firefox did work at first, but then something happened, I don't know what, and then Firefox just stopped working. I've uninstalled and reinstalled, did Refresh, tried to start it up in Troubleshoot mode, and nothing works. It'll open, and it'll show bookmarks, but if I try to go to a website, it just sits there and doesn't do anything. Doesn't act like it loads no matter how long I let it sit. I've tried to do about:config to maybe turn off ipv6 or http3, i type in about:config and it doesn't load. I tried to go to settings or to view passwords and it just puts in about:login...... in the address bar and just sits there. I'm not sure what's going on and any advice would be welcome. I've uninstalled all AV and am currently just using windows defender firewall, which I have also disabled as well and it didn't make a difference. Any advice or tips or fixes would be more than welcome.
Firefox also doesn't shut down when I close it. I have to close it in task manager in order to start it up again

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":

- https://aka.ms/vs/17/release/vc_redist.x64.exe
- https://aka.ms/vs/17/release/vc_redist.x86.exe
You may also have to install the Visual Studio 2013 Redistributable Package. You need to reboot the computer.
It is possible that your firewall or other security software blocks or restricts Firefox without informing you, possibly after detecting changes (update) to the Firefox application. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access for Firefox and the plugin-container process and the updater process.

You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
