Note: Before you do any of these tweaks, you should download or update to the latest version of Firefox by going to About Firefox.
Once you have had Firefox installed for some time, it can take a long time to start up. Meanwhile, browsers like Chrome, Edge, and Safari seem to launch immediately. Here’s what you can do to make Firefox boot faster.
After using Firefox for some time, it starts using a lot of CPU process or RAM. To find out the cause of the slowdown, first try restarting Firefox in Safe Mode. This will make Firefox run without any add-ons or plugins. To do this, go to Options (the three-line icon at the extreme right of the URL bar) > Question Mark > Restart with Add-ons Disabled.
Firefox will restart and display two options: Start in Safe Mode or Refresh Firefox. Choose Start in Safe Mode.
If Firefox runs faster in Safe Mode, then you know the problem lies in one of the add-ons or plugins. Disable all add-ons, and restart Firefox. Then enable one add-on at a time, and see which one causes the problem.

If all else fails, it’s time to go back to a clean installation of Firefox. But you don’t have to start from scratch all over again.
Much like operating systems, the browser now has a one-click option to return to the default Firefox state before you made any changes. Specifically, it will remove all add-ons and customizations, and restore browser settings to defaults.
Firefox will shut and restart in a few seconds.
