Block unneeded content
Content you don't need such as ads or tracking scripts can significantly slow down page loading. Firefox's built-in Content blocking can make the pages load faster by preventing third-party trackers from loading. See Content blocking for details.
There are also Firefox add-ons that can block content you don't need, such as:
- The Disconnect add-on blocks invisible webpage parts that track you online.
- The uBlock Origin add-on blocks ads, trackers and other unneeded content while using less memory and CPU resources than other adblockers.
- The NoScript add-on allows you to selectively enable and disable all scripts running on websites.
