First of all, make sure you have the latest version of Firefox installed. Mozilla has been introducing several speed improvements to its browser, and you want to take advantage of them.

4) Don’t use the Session Restore feature

If you set Firefox to use the Session Restore feature to show your windows and tabs from last time, Firefox can take a long time to start if you had lots of websites open the last time you used Firefox.

Ensure that the default setting of Don’t load tabs until selected, is checked. In this case, only the last selected tab is loaded at startup.

5) Uninstall or Disable Add-ons & Plugins

Uninstall or Disable Add-ons, Plugins, or 3rd-party extensions you don’t need. To do so, via File Menu, click on Manage Addons. Here you can manage your add-ons, plugins, and extensions too. Also, remove Userscripts if any.

You might actually find your Firefox running much faster even if you disable slow-performing add-ons and plugins.

6) Avoid Themes

Avoid using themes. Switch to the default theme if you are using one.

7) Reset Firefox

When you find that your Firefox keeps slowing down and becoming sluggish in spite of doing everything, Reset it.

It will save some of your personal information like Bookmarks, Browsing history, Passwords, Cookies, and Web form auto-fill information. But it will not save installed Extensions, themes, tab groups, personal preferences, customizations, etc.

8)  Reinstall Firefox

If you find nothing working, reinstalling Firefox, after backing up your Bookmarks and Settings, using freeware MailBrowserBackup or FavBackUp might be a good idea.
