Connection settings in Waterfox

Your organization or Internet service provider may offer or require you to use a proxy. A proxy acts as an intermediary between your computer and the Internet. It intercepts all requests to the Internet to see if it can fulfill the request using its cache. Proxies are used to improve performance, filter requests, and hide your computer from the Internet to improve security. Proxies are often part of corporate firewalls.

Connection settings to use a proxy can be set in Waterfox Options as follows:

  1. Click the menu button menu button and select Settings.
  2. In the General panel, go to the Network Proxy section.
  3. Click Settings…. The Connection Settings dialog will open. Fx63ConnectionSettings
