Mozilla Firefox is one of the oldest and most trusted browsers for Windows 10 users. With millions of users, Firefox is reliable and one of the most useful browsers. But while sometimes it may work as expected, it is not uncommon for Firefox to present some problems when you try to use it. For Windows 10 users, one of the most problematic issues is when Firefox keeps crashing for no apparent reason. It can happen as soon as you turn on Firefox or when you open more than one tab on the browser.

It is important to note that this problem can occur for multiple different reasons and under different circumstances. Fortunately, there are several ways you can fix this problem once and for all and get Firefox working normally again.

Part 1: Why Does My Firefox Keep Crashing?

There are very many reasons why Firefox may be crashing on Windows 10. Some of the most common include the following;

Part 2: How Do I Stop Firefox from Crashing?

Just as there are varied causes of this problem, there are also a lot of different solutions that you can try. The following are some of the most effective;

Method 1: Update Firefox

Having the latest version of Firefox is one of the best ways to prevent this problem from recurring. Therefore the first thing you want to do is to check if you are running the latest version of Firefox. Follow these simple steps to do it;

Step 1: Open the Firefox browser on your computer and then click on the browser's menu. Select "Help" from the options presented and then choose "About Firefox"

Step 2: A new window will open and begin looking for available updates for Firefox. If an update is available, Firefox will download and install it immediately.

Step 3: Once the update process is complete, click on the "Restart to Update Firefox" button to complete the process.

Method 2: Clear Firefox Cache

The cache is data that Firefox and other browsers may save on your system to help websites load faster. But when the cache is corrupted it can have the opposite effect, even causing the browser itself to crash at inopportune moments. In this case, the best way to fix the problem is to clear the cache on the browser. Here's how to do it;

Step 1: Open Firefox on your computer and then click on the menu button (the three lines on the top left corner)

Step 2: Select "History" in the options presented to open a side menu with more options. In these options, click on "Clear Recent History"

Step 3: Click on the "Time Range to Clear" drop-down menu and then select "Everything"

Step 4: Select the data and items you would like to clear and then click on "Clean Now"

Restart Firefox when the process is complete to see if the problem is gone.

Method 3: Disable Firefox Add-Ons

Step 1: Open Firefox on your computer and then click on the menu icon (three lines)

Step 2: Click on "Help"

Step 3: Select "Restart with Add-Ons Disabled" and then click "Restart" in the dialogue box that appears.

Method 4: Check for Viruses

Viruses and malware can also be a major cause of a crashing Firefox. The same is true for any software that may be incompatible with Firefox. If the problem began soon after you installed a certain program, then it is likely that the newly installed program could be incompatible with Firefox and may need to be uninstalled.

It is also important to run a full system check for your PC using powerful antivirus software. There are a lot of third-party antivirus programs you can use but you can also use Windows 10 Defender to scan your system.

Method 5: Update your Drivers

Sometimes the problem is not with Firefox but with the drivers on your computer. Therefore, updating the drivers could help keep Firefox from crashing. To update drivers on your Windows 10 system, follow these simple steps;

Step 1: Press the Windows Key + R on your keyboard to open the Run dialogue

Step 2: Type in "devmgmt.msc" into the dialogue box and then press "Enter". This will open the Device Manager.

Step 3: You should see a list of all the devices on your device. Any devices that need a critical update will be marked with a yellow exclamation mark.

Step 4: if you don't see any critical updates, locate the most important drivers, necessary to keep your computer running normally. Right-click on the device and then select "Update Driver"
