In addition to editing the config file, we’ll also go over some other plugins and things you can do to greatly increase the speed if Mozilla Firefox. In this article, we will explain a step by step process to make the Firefox browser faster and more efficient by editing the about:config file. Moreover, the web developers at Mozilla are consistently working on making important changes to make the Firefox browser faster.Īlthough Firefox is considered quite fast, over time you may be prone to download apps and plugins that slow the overall experience and loading times. With its plethora of useful apps and plugins, Firefox has become a very useful browser to have for both businesses and personal use. If you need to run 32-bit Firefox or manually install 64-bit Firefox, you can simply download and re-run the Windows (32-bit or 64-bit) Firefox installer from the Firefox platforms and languages download page.Mozilla Firefox is one of the most useful and popular internet browsers in the market.
You can still manually install 64-bit Firefox, if you choose. If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more).If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number: If you’re running 64-bit Windows ( here’s how to check), your Firefox may already be 64-bit. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit.

In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more. That means you get a more secure version of Firefox, one that also crashes a whole lot less. Users on 64-bit Windows who download Firefox can get our 64-bit version by default.
