If you find Firefox has been running so painfully slow that even loading a single page takes forever, don’t worry. Here’re 5 tricks that have helped other users resolve the problem. So read on and check them out…

Try these tricks

All the tricks below work in Windows 10, 8 and 7.

Just work your way down the list until your Firefox behaves again. 

  1. Clear browser data and disable the unused add-ons 
  2. Switch the hardware acceleration 
  3. Update your video driver
  4. Resolve problems with unresponsive script
  5. Run a virus scan

1. Clear browser data and disable the unused add-ons 

Clearing browser data would probably be most people’s knee-jerk reaction to a choppy Firefox as too much history data will cause our browser to overload.  To clear browser data:

  1. In Firefox, click the menu icon  and click Options.
  2. Click Privacy & Security > Clear Data….

After that, another trick you can do is to disable the unused add-ons. Here’s how:

  1. In Firefox, click Add-ons.
  2. Turn off the toggles of the add-ons that you don’t often use.
  3. Re-launch Firefox and see if it runs faster.

2. Switch the hardware acceleration 

Hardware Acceleration or GPU Rendering is a new feature in our browser that tasks GPU with all the graphics and text rendering. But depending on the make of your computer, you might have to switch it to the opposite for optimal browser performance.

  1. In Firefox, click the menu button > Options.
  2. Scroll down to Performance, then un-check the box before Use recommended performance settings and CLICK the box before Use hardware acceleration when available.
  3. Re-open Firefox and check if the slow Firefox issue has been resolved.

3. Update your video driver

Your FireFox slow issue may very well be the early sign of an outdated/corrupted video driver on your computer. So you should update your video driver to see if it fixes your problem.

If you don’t have the time, patience or computer skills to update your drivers manually, you can do it automatically with Driver Easy. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.  
  3. You can upgrade to the Pro version and click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system.
    You can also click Update to do it for free if you like, but it’s partly manual.
  4. Fire up Firefox and see if the slow Firefox issue has been sorted.

4. Resolve problems with unresponsive script

Unresponsive script is another reason responsible for this sluggish Firefox problem. To resolve the problems:

  1. In Firefox, copy & paste about:config into the address bar, press Enter and click I accept the risk.
  2. Copy & paste dom.max_script_run_time into the box and double-click on the search result.
  3. Type 20 in the value box and press OK.

Firefox still not getting any faster? Try Trick 5.


5. Run a virus scan

Another possible reason for this Firefox slowdown issue is malware attack, which can develop into a more serious problem like system crashes if unattended. So we might have to run a virus scan to keep things at bay. 

Norton is a trustworthy award-winning antivirus program in keeping you protected from existing, new, and even yet-to-be-invented threats with patented technology.

Give it a try now and keep your computer in good health!
