Firefox is the market’s second most used browser. Users all across the world utilize it on many platforms. Although it is sophisticated enough to cater to literally all contemporary needs, there can be frustrating issues as well. If you’ve arrived here because Firefox won’t open, you’re not alone, and you’ve come to the right blog.
We’ll show you how to fix the problem in this post. The steps below are simple to follow and can get completed by anybody with or without the tech knowledge.
Firefox Won’t Open? Even after double-clicking?
Many people have recently complained about “Firefox Won’t Open” issue. It’s pointless to keep double-clicking the icon, when this problem occurs. Some users reported seeing the Firefox loading symbol for a split second, while others saw no change at all. Regardless of the state of the concern, these are some of the most common causes of this issue:
- Drivers can occasionally cause issues by interfering with other programs. The newest drivers for devices built into or attached to your computer may impact Mozilla Firefox. It’s possible that uninstalling drivers will fix the problem.
- Firefox allows you to install extensions that enhance the browser’s functionality. These add-ons can also damage Firefox if they get poorly written or include a bug. Getting rid of the add-ons usually solves the problem.
- There are instances when files get corrupt on their own, and you can do nothing about it. Corrupted files too cause this issue. To resolve the problem, we recommend deleting all data and reinstalling Firefox.
To determine if your Firewall and antivirus are causing the problem and Firefox won’t open, disable them temporarily to see they are the culprit of this issue.
Note: Don’t forget to enable it later on to protect your device from Malware.
Troubleshooting Methods for Firefox won’t open
Here are the easiest solutions you can implement to overcome this frustrating situation.
Kill Firefox Process from Task Manager
One of the reasons could be that Firefox is already running in the background. Use the task manager to close the Firefox entirely and to try to open it again. Use the combination of Crtl+Shift+Esc to access the taskbar quickly. Mozilla Firefox is on the Applications dropdown in the Process tab. Select the list of running processes related to Firefox and, by right click, end the task. Start the Firefox to see if the problem gets fixed.
Reinstalling Mozilla Firefox
Corrupted files are the root of the problem; in that sense, reinstalling Firefox is always a good idea. The most frequent remedy for damaged files is to replace them with a faulty-free duplicate. However, it’s challenging to figure out which file is causing the problem because we don’t get any error messages. Close all the processes of Firefox from the task manager as described above and uninstall the Firefox from program features in the control panel.
Download the newest version of Mozilla Firefox from its official website. To reinstall it, run the downloaded setup and follow the on-screen instructions.
Deleting add-ons is a fantastic approach to address Firefox’s not functioning problems, mainly if they occur after installing new add-ons. You’ll have to perform it in safe mode because Firefox isn’t launching right now. It’s feasible because Firefox runs in safe mode with the bare minimum of software and hardware.
Use command port to access the Firefox in safe mode. Start the command prompt by typing cmd in the run dialogue box to open the command prompt.
Type in “C:\Program Files\Mozilla Firefox\firefox.exe” – to start Firefox in safe mode.
- Once the Firefox gets opened in the safe mode
Type “about: add-ons” in search bar
- Disable all the latest installed add-ons and close the Firefox
- Now recheck by opening the Firefox, if the issue is fixed or now.
Delete Startup cache
Sometimes cache memory stores several corrupted files and inturn causing issues to Firefox running processes. To remove your Firefox startup cache, head toward this path in your file explorer by changing the word Username to your profile name in the file path below.
Clear all the files in the startup cache folder. Alternatively, If you were able to open Firefox in safe mode, this method can get done quickly by
Typing about: support in Firefox address bar and hit Enter.
Press the Clear startup cache label to achieve the process.
Logitech Cam Drivers
According to several users, the latest version of the Logitech cam driver might create various issues with Firefox. You must remove this Logitech cam driver to resolve the issue.
- To open the Run dialogue box, hold down the Windows key and click the “R” key simultaneously.
Type devmgmt.msc and press Enter
- Select Uninstall from the menu that appears when you right-click on your Webcam drivers. After that, restart the system.
Check to see condition of the error. If everything is ok, you may download an earlier version of the webcam driver from Logitech’s website, or Windows will install a generic driver for you. These generic drivers aren’t the finest, but they’re functional and safe.
