I have to sign-in to my computer this morning, which normally indicates a Microsoft update ran the previous night. DuckDuckGo, Chrome, and Edge all seem to be able to pull up website; not so for Firefox. I redownloaded Firefox - no change. I deleted Firefox, ran CCleaner, and downloaded the software again - no luck. I cleaned my registry of its orphan files - no luck. I turned off my VPN - no luck. So I am forced to use another browser until I can get this fixed. Suggestions?
