Disable image rendering in Firefox

Sometime ago I did not have an ADSL internet connection at home. I managed to make my smartphone a hotspot and accessing its internet connection via my laptop. Disabling the image rendering proved to save some change. You only need to adjust the settings via about:config.

  1. Open Firefox
  2. Type about: config in the address bar.
  3. Search for permissions.default.image and adjust the value to 2. The default value is 1 by default.

    Value Description
    1 Allow all images to load
    2 Block all images from loading
    3 Prevent third-party images from loading
