Mozilla Firefox slow on Windows 11 24h2
Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

This crazy slowdown is related to DNS Proxy settings in Mozilla Firefox. Setting this to "No proxy" or to "Auto-detect proxy settings for this network" resolves the speed issue and Mozilla Firefox is flying again. Please investigate.

This fixed it! Updated to 24H2 last night. Began having all sorts of video related stuttering issues on the PC, reverted and re-reverted graphics drivers a few times, then noticed Firefox was stuttering and even mouse response time was lagging. Changing the setting to No proxy instantly fixed it. Thank you!
