How to Resolve Firefox's Won’t Open

Here we can see, “How to Resolve Firefox’s Won’t Open”

Many people recently complained about “Firefox not opening.” The difficulty is that many folks cannot open Firefox. Double-clicking the icon or launching the browser as the administrator has no effect. Some users saw the Firefox loading indicator for a split second, while others saw no change. The issue isn’t that Firefox doesn’t show up on the screen, but it won’t start. Many users confirmed this by checking the Task Manager. When you double-click the Firefox icon, the Task Manager shows no Firefox instances. There will be no error notice, making troubleshooting difficult.

What causes Firefox to Not Open When Double-clicked?

The main causes of this problem are:

  • Not 100% sure, but all clues lead to a corrupted file. Sometimes files become corrupt on their own, with no recourse. Because deleting everything from the system and reinstalling Firefox fixes the issue, we assume damaged files.
  • Add-ons: Firefox lets you install add-ons that extend the browser’s functionality. But these add-ons can also create Firefox issues, especially if they are poorly built or include bugs. So removing the add-on usually fixes the issue.
  • Drivers can sometimes cause trouble by interfering with other apps. The latest Logitech webcam drivers are known to create difficulties with Firefox, and Uninstalling the drivers may help you.
  • Disable your antivirus and firewall to see if they are causing the issue.

Warning: Disable your antivirus or disable your firewall at your own risk.

Method 1: Reinstall Firefox

A corrupted file is the most likely culprit. Therefore reinstall the browser. The typical cure for a corrupted file is replacing it with a good duplicate, but it’s difficult to identify the culprit without an error message. Reinstalling Firefox generally cures the issue. Remember that uninstalling Firefox won’t get rid of all the Firefox files. This solution requires a set of procedures to be followed in a specific order. So, follow these steps.

  1. To open the Task Manager, use CTRL + SHIFT + ESC.
  2. Firefox should be listed there. If any instances are found, pick Firefox and click End Task. This is to ensure that no instances of Firefox are running, which would prohibit removing the program.
  3. Hold Windows and E
  4. Enter C:\Program Files in the address bar
  5. Right-click the Mozilla Firefox folder and select Delete.
  6. Enter C:\Program Files (x86) in the Address bar.
  7. Right-click the Mozilla Firefox folder and select Delete.
  8. Hold Windows key and enter appwiz.cpl.
  9. Select Mozilla Firefox from the program list.
  10. Click Uninstall and follow the prompts.
  11. Reboot

Download the newest Firefox version from the Mozilla Firefox website.

After downloading, start the setup and follow the on-screen directions.

After the installation, everything should operate as planned.

Method 2: Remove Add-ons

That would be solid advice, especially if you detected the problem after installing an add-on. You can no longer uninstall the add-on without opening Firefox in Safe Mode. Safe Mode works because it runs Firefox with minimal software and drivers. So, if a third-party add-on was creating the issue, you will know. To open Firefox in Safe Mode and remove add-ons, follow the steps below.

  1. Hold SHIFT while starting Firefox. This starts Firefox in Safe Mode. If a dialogue box appears asking you to confirm your actions, click Start in Safe Mode.
  2. If Firefox opens, an add-on is most likely to blame. Follow the steps below to disable all add-ons.
  3. Enter about:addons in the URL bar.
  4. Disable all add-ons on this page. Every add-on should have a Disable button.
  5. Close Firefox after disabling all add-ons.
  6. To fix this, restart Firefox (without pressing Shift).
  7. Enter about:addons in the URL bar.

Now you should click Enable for each add-on to check which is the problem. Repeat steps 1 and 2 to open Firefox in Safe Mode and get to the add-ons page. That’s it for that a, and you. You should be fine.

Method 3: Delete Logitech Cam Drivers

The latest Logitech cam drivers are known to create difficulties with Firefox. It’s the Logitech Webcam Pro 9000 driver. To be safe, delete the driver even if you have another Logitech Webcam. Uninstalling the cam drivers should solve the issue. Uninstall the Logitech Webcam drivers using the procedures below.

  1. Hold Windows and R.
  2. Enter devmgmt.msc.
  3. Double-click the Imaging device.
  4. Uninstall Webcam drivers by right-clicking.
  5. Reboot the PC.
  6. See if this helps. It may be necessary to obtain an older version of the webcam from Logitech or let Windows handle the driver issue. If you don’t have a driver, Windows installs one. These generic drivers aren’t the best, but they’re safe.

If nothing else works, create a new Windows user account and use Firefox as that user.
