Firefox dates back to the early days of the Internet in its current manifestation. Created as an open source project in 2002, by a group of developers working for and with Netscape in 1998, before they were bought by AOL. The Mozilla community set about creating a web browser that would challenge Internet Explorer, making it the successor to the original Netscape Navigator.

Google’s biggest rival

Firefox was then launched in 2004, earning over 60 million downloads in 9 months. It has grown in popularity over the years, with people using it on laptops, tablets and mobile devices, now with over half a billion users worldwide across every device and platform. However, it isn't a perfect browser, and at times we are forced to ask why is Firefox so slow?

Thankfully, there are a number of ways you can speed up and improve the experience, and improve Firefox performance.

Here are a few ways to quickly and easily speed up Firefox on a Mac.

How to speed up Firefox?

1. Use hardware acceleration

Hardware acceleration is when a browser uses a computer’s GPU to load pages more quickly, which is something you can do with Firefox Quantum. For quite a few computers, this is something that isn't automatically enabled, so you need to do this manually. Here is how:

Use this to decide how much GPU to let Firefox use if you've got the capacity, if you think anything more than 4GB is needed (which is the minimum default setting).

Enabling hardware acceleration and content processing limits are the first things you should check if you want to speed up how Firefox operates. However, there are other ways to improve the speed and overall performance of Firefox.

2. Delete Internet plugins

One of the things slowing Firefox down could be Internet Plugins and Launch Agents — small background apps that you aren't even aware of.

Another way Firefox is always looking out for its users is through something called Accessibility Services.

Launch Firefox
Go to About > Preferences
Click on Privacy & Security
Check the Prevent accessibility services from accessing your browser box
