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

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.
