How to Speed Up Firefox Without Closing Tabs

The newest version of Firefox, also known as Firefox Quantum, is capable of handling quite a few tabs — Mozilla says up to 100. But Firefox could be running slowly regardless of how many tabs you've got open.

We'll show you how to use tab suspension to speed up Mozilla Firefox without closing tabs, as well as other proven methods.

How to make Firefox run faster:

Update and restart Firefox - Easy

Time to complete: 1 minute

The top browsers are constantly updated to improve performance, and Firefox is no exception. Make sure you’re on the latest version here. If Firefox is up to date, it’s a good idea to restart, since it can use more system resources the longer it’s left open.

Use a tab suspender - Easy

Time to complete: 1 minute

Try using a tab suspender for Firefox such as Workona or Auto Tab Discard. Using a tab suspender means that your tabs are only loaded when you need them (i.e. when you click into them). This allows you to keep lots of tabs open without slowing down your device.

How can I increase my browser speed?

If you're in the habit of opening lots of tabs, or your device has less processing power (like older computers in general), you should consider using a reliable tab suspender like Workona. It can help you manage tabs, organize projects, and bring together all of your work in the cloud.
