How to Fix: Firefox is not set as the default browser on Windows 10

Here we can see, “How to Fix: Firefox is not set as the default browser on Windows 10”

Many Firefox users are reporting that Windows 10 won’t accept Firefox as their default browser. Most impacted customers claim that they can designate Chrome or another browser as the Default, but not Firefox.

Why can’t I set Firefox as my default browser?

We looked into this issue by looking at user reports and their remedies to make the setting permanent. Our research has identified a few prevalent conditions that cause this erroneous behavior:

  • Bad Firefox installation – A faulty or incomplete installation causes Windows to ignore your’ set as default’ requests. This usually occurs after removing a browser hijacker or other adware/malware from Mozilla Firefox.
  • A Windows upgrade broke Firefox — Both Microsoft and Mozilla admitted that a Windows 10 upgrade broke the ‘set as default’ functionality for Firefox. In this scenario, reinstalling the browser is sufficient.

This post will present you with many troubleshooting solutions to resolve this particular problem. Other people have successfully adopted several solutions in a similar circumstance.

If you want to be as efficient as possible, we recommend following the procedures efficiently and severely.

Method 1: Reinstalling Firefox

If the problem is due to a poor Firefox installation, reinstalling the browser and all its components will quickly fix it. It appears that this technique finally enabled Firefox as the default browser on Windows 10 computers.

Reinstall Mozilla Firefox to fix the ‘can’t set Firefox as default browser’ error:

  1. To launch the Run dialogue, press Windows + R. Open Programs and Features by typing “appwiz.cpl” and press Enter.
  2. To uninstall Mozilla Firefox, navigate to the Programs and Features screen, right-click on the browser, and select Uninstall.
  3. Follow the on-screen directions to uninstall Mozilla Firefox.
  4. Restart your computer after uninstalling it.
  5. Go to this link (here) and click on Download Now to get the Mozilla Firefox installation executable at startup.
  6. After the installation, accept the User Account Control (UAC) and reinstall Mozilla Firefox by following the on-screen instructions.
  7. When you initially launch the browser, you are asked if you wish to make it your Default. Set Firefox as your default browser when requested.

Try the following method if this approach didn’t work or the setting didn’t stay after a restart.

Method 2: Changing the default browser from the Default Apps

Most customers who had trouble getting Windows 10 to remember Firefox as the default browser reported success by changing the default browser from the Default Apps option.

This method makes Windows 10 more likely to detect Firefox as the default browser. Changing the default browser via the Default Apps menu is easy:

  1. To launch the Run dialogue, press Windows + R. Then enter “ms-settings:defaultapps” to open the Settings app’s Default apps menu.
  2. Scroll down to the Web browser area, click on the default browser, and select Firefox from the newly displayed choice.
  3. Restart your computer and see if Firefox remains the default browser.

If the previous setting does not survive, proceed to the next method.

3: Using the Control Panel menu

If the two approaches above didn’t work and Firefox is still not recognized as the default browser, you might use the old Control Panel menu. Several impacted users stated that changing the default browser via the previous Control Panel interface made the change permanent.

Here’s how to change the default browser using the traditional Control Panel menu:

  1. To launch the Run dialogue, press Windows + R. Then type “control” or “control.exe” and hit Enter to access the Control Panel.
  2. Use the top-right search option to find “default programs” in the traditional Control Panel. Then select Default Programs from the list.
  3. Set your default programs from the Default Programs menu.
  4. Scroll down to Web browser and select Firefox from the selection.
  5. Restart your computer to see if the modifications are retained.

Using the Choose defaults for this program menu has been reported to work for people who attempted most of the other techniques above without success.

What you must do:

  1. To launch the Run dialogue, press Windows + R. Then enter “ms-settings:defaultapps” to open the Settings app’s Default apps menu.
  2. Scroll to the bottom of the screen and select Set defaults by app (above Choose your default apps)
  3. Scroll down the list and select Firefox in the Set defaults by app section. Then select Manage to access the Firefox menu.
  4. Next, update all file types and protocol associations to Firefox.
  5. Restart your PC once all supported file types are Firefox.
