Whenever I try to open a web page it I get this message: "The connection has timed out, the server at [website]is taking too long to respond."

The school Wi-Fi network uses a proxy, and I've made sure the Firefox proxy settings are the same as Chrome and Edge, both of which work fine. Firefox works fine on my home Wi-Fi, so it's specifically Firefox on the school internet that's the problem.

Check with the school's IT. Have you tried other browsers?

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
