I updated Windows 11 to 22H2 yesterday, Firefox will not start, Edge runs fine. I think Microsoft is blocking Firefox.

Oh stop it... ;-)) Can you log into windows under a different account and see if it works? If you have the same issue, boot Windows into safe mode and try again. Let me also boot into Win 11 and see what happens.

For me, Firefox v109 just stopped opening on Windows 11 22H2. It worked the other day. No Windows updates but three driver updates for "HP Inc - SoftwareComponent" ver.1.0.806.0, 1.51.3297.0 and 4.2.1217.0, and a "NVIDIA - Display - 31.0.15.2656" update in the last 2 days. I refreshed Firefox. I downloaded and installed it again without uninstalling first. Then uninstalled and reinstalled it and it still will not run on my computer. MS Edge and Google Chrome browsers work without any problems at all, in both regular and incognito. I'm still digging into this but haven't found my solution yet.
