I just downloaded Firefox on my new Windows 11 computer and I'm having this problem where I try to open it and it immediately closes. It just flashes on the screen, I tried downloading it off of the Mozilla site and the Microsoft store and both times I've been having this issue. It doesn't show up in task manager when trying to open it, my computer is updated, and I'm connected to Wi-Fi. I have a video of the issue but it wont let me put videos here.

Your Microsoft account may have parental controls enabled which limits what browsers you can use, you could try to get this limitation removed or create a new account. Renaming firefox.exe to something else can get it working but this will break DRM protected videos.
