How To Fix Slow Firefox Browser

Change the homepage

If your Firefox takes a lot of time to start, the cause might be from the homepage you previously set. According to Firefox, Problems with a website can cause Firefox to take a long time to start. Try changing your Firefox home page to the default home page or a blank page. See How to set the home page for instructions on how to change your Firefox homepage.

Check your antivirus software

Your Firefox browser is programmed to read a number of files normally during startup. Some antivirus software on your PC may do intensive scans of each of these files during startup and block access until those scans complete. If the problem began after installing, updating, or reconfiguring your antivirus software, contact the software provider for assistance, or you could just try disabling your antivirus software.

Check installed extensions and themes

Here’s another thing that could slow down your Firefox browser. If you have 50 extensions download and 50 themes downloaded on your browser, I don’t think that’s a good idea. That may be the cause of your slow Firefox browser. Try disabling downloaded extensions and removing themes and thank me later. If you have a lot of extensions and themes and want to be sure if they are the cause of your laggy browser, try to disable all of them, reload your browser and see if the lag persists.

Optimize Windows

This is as simple as it can be. If your PC is slow your Firefox will also be slow. Try to Speed up your Windows and make your computer work better and faster. Clean up your computer, clear files you are not using anymore, clear your recycle bin, free up space on your Hard disk. That’s not all. You can also upgrade your windows version or install an antivirus program to fight malware. Make sure your drivers are up to date. There are lots of ways to optimize your PC to make it work faster which will, in turn, fix slow Firefox browser.
