I cannot open the Mozilla download page. It seems not to download anything, as I m taken to the error page (see image).

I read a support thread on the issue but I could not understand, it seems like an issue that requires previous knowledge, and I think it should be easy for old, loyal users of Mozilla to have a simple solutions for access to Mozilla site, with... Mozilla browser!

It started to happen yesterday, so far I never had such difficulty.

Thanks,

You can check the connection settings and check for possible issues with a Proxy or VPN service.

  • 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.
