Hey Tom! Thanks for reporting this. It's not your fault but appears to be caused by NordVPN. You might have this program installed. If you do, you need to disable a feature it uses called "Web Protection". Thanks for making us aware of your age & I hate to make you fiddle with options! But if you could try to follow this screenshot, you will find the area you need to turn off Web Protection: https://i.imgur.com/UshEkTL.png I apologize if your NordVPN does not look exactly like the above photo. They constantly redesign and change the look of their program. So try to focus on just finding the words "Threat Protection" and "Web Protection". Step by step instructions: * Open the NordVPN program (The desktop shortcut will be similar to this: [https://i.pcmag.com/imagery/reviews/07lyyVIatWNmQKm97hGohzg-9.fit_lim.size_1200x630.v1569477664.png Screenshot]) * Click on the Shield icon on the left side of the program * You should be in a area called "Threat Protection" * Click the circle button on Threat Protection to turn it off * If there's a circle button on Web Protection, click it as well to turn it off * If a popup box appears saying "Reconnect to VPN to apply Settings", click the Reconnect button * Open Firefox & look to see if anymore update errors appear Please let us know if this fixed your problem. Apologies in advance if you do not have NordVPN installed. ----- '''Credit to who solved this issue''' A user reported NordVPN was blocking Firefox updates since March 23rd: https://www.reddit.com/r/firefox/comments/1bly9xz/firefox_suddenly_unable_to_auto_update/ Solution: "Figured it out. When NordVPN "Web Protection" is on, it fails to check for updates from the About menu as well. When "Web Protection" is off, it correctly checks for updates. I surmise that when Firefox fails to check, it assumes that I need an update and gives the original annoying message."
