Disable Prefetch
Prefetch is a Firefox feature, enabled by default, that allows websites to cause your browser to download pages you did not request. For example, "On some searches, Google automatically instructs your browser to start downloading the top search result before you click on it. If you click on top result, the destination page will load faster than before."—Google Help Center, Results Prefetching
To disable prefetch:
- Type "about:config" the address bar.
- Scroll down to the setting "network.prefetch-next".
- Right click and select "Toggle" to change the value to "False".
Advanced Fun
Beware
- Many modern Firefox extensions (add-ons) may interact with the vendor website and collect data about you and what you are doing with their software. It's also common for add-ons to check for updates periodically but this can usually be turned off in the preferences. Always read the description of an add-on and understand what it is doing before the install.
