Hi, I have just returned from China. I use a Macbook Pro and am operating Firefox 118.0.2 (64-bit) I now find that when I use Firefox to access websites blocked in China (i.e google, the Guardian) I get a "Did Not Connect: Potential Security Issue" message. I can access everything with a VPN active I also got this for Microsoft Edge but the problem resolved by clearing cookies (didn't work for firefox) How can I fix this

Country can block or allow Browser access and since this is China there nothing Firefox can do if another country blocks or denies access. VPN access is up to the VPN provider to resolve connections issue on their side.

Sorry, just to be clear, I am no longer in China. I am in the UK. Sites that I can normally access fine in the UK are now still blocked. Other websites work fine

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet, select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.
