• Poor network connection: Slow or unstable internet connection can prevent Firefox from accessing web pages.
• Outdated browser version: Using an outdated version of Firefox can lead to errors, including the inability to load pages.
• Corrupted browser cache: A corrupted browser cache can cause issues with loading web pages.
• Third-party software interference: Certain third-party software can interfere with Firefox, causing it to fail to load pages.

10 Methods to Resolve Firefox Pages Not Loading Error

Method 1. Start Troubleshooting in Safe Mode

To pinpoint the causes of the Firefox not loading pages issue, it’s recommended to begin troubleshooting in Safe Mode. This mode disables all hardware acceleration and extensions and changes the browser theme to the default setting, making it easier to identify any potential issues. If pages load normally in Safe Mode, the problem may be related to one of these factors. However, if the problem persists, it could be due to a setting that Safe Mode doesn’t change, or a faulty plugin may cause it.

Alternatively, you can follow these steps to start Troubleshoot Mode.

Troubleshoot Mode

To disable add-ons in Firefox, follow these steps using troubleshooting mode:

1. Launch Mozilla Firefox.

2. Click the horizontal three-bar icon at the screen’s top-right corner.

3. Select the “Help” > “Troubleshoot Mode” option.

4. Click “Restart” in the confirmation dialog box.

5. Firefox will now boot to Safe Mode. If you can access websites in this mode, the issue may be related to third-party extensions.

Method 2. Close Other Browsers Running in the Background

If you frequently use multiple web browsers simultaneously, monitoring your computer’s memory usage is important as it can impact browser performance. Closing all parallel browsers may help eliminate any external interference causing the issue. Moreover, suppose you encounter problems with page loading after importing data from another browser. In that case, reverting the import and resetting Firefox is worth considering, as a hidden bug could have been imported and affected the browser’s performance.

Method 3. Clearing Firefox Cache

Like other web applications, Firefox stores a significant amount of data in its browser cache to improve the loading time of visited websites by retaining site information for future use. However, accumulating data or corrupt cache files can sometimes impact the browsing experience. Thus, it’s essential to clear the browser cache. Here are the steps to do so:

1. Open Firefox.
2. Click on the three horizontal lines in the top-right corner.
3. Navigate to History > Clear recent history.
4. Tick off the boxes for Active logins and Form & search history.
5. Select “Everything” from the dropdown menu in the Time range to clear.
6. Hit “Ok”.

Method 4. Reboot Mozilla Firefox

In case you are still facing the problem of Firefox not loading pages, it could be due to the current preferences set on your Firefox browser. You can try resetting your browser to its default settings to verify this. However, note that this will reset browser preferences and themes, but your bookmarks, cookies, and passwords will be retained.

1. Click on the Firefox menu icon and hover the mouse over the Help option.

2. Click on Troubleshooting Information.

3. Click on the Reset Firefox to its default state button.

4. Confirm the action by clicking on the Reset Firefox button in the pop-up window that appears.

5. Wait for Firefox to reset to its default settings and restart automatically

Method 5. Disable DNS Prefetching

DNS Prefetching is a feature that automatically retrieves resources related to a DNS lookup that the browser might request. This allows the browser to load the site a few seconds faster since the DNS lookup has already occurred. However, in some cases, this prefetch technique could result in incorrect loading configurations or break websites. Thus, it may be worth disabling this feature to see if it resolves the Firefox not loading pages issue.

To disable DNS prefetching in Firefox, follow these steps:

1. Launch Mozilla Firefox and navigate to the “about:config” page in the address bar.

2. Click on the “Accept the Risk and Continue” button.

3. Type “network.dns.disablePrefetch” in the search bar and press Enter.

4. Click the toggle button on the right to change its value from False to True.

5. Try reloading the site and check if it resolves the Firefox not loading pages issue.

Method 6. Disable IPv6

By default, Mozilla Firefox enables IPv6 protocol which may lead to connection problems in some systems. If you encounter this issue, you can disable the IPv6 protocol in the Firefox browser by following these steps:

1. Launch the Firefox browser on your computer.

2. Type “about:config” in the search box and press Enter.

3. Click on the “Accept the Risk and Continue” button.

4. Search for “network.dns.disableIPv6” in the search box and press Enter.

5. Toggle the button next to “network.dns.disableIPv6” to make it “True” instead of “False.”

6. After disabling IPv6, try reloading the site to see if the issue is resolved.

Method 7. Check Proxy Settings in Firefox

To troubleshoot Firefox proxy server connection settings, follow these steps:

1. Select the Menu Button and then click on Preferences.
2. Go to the Advanced panel and choose the Network tab.
3. Under Connections, select Settings.
4. If you do not use a Proxy Server, select No Proxy.
5. If you connect through a Proxy Server, compare the Proxy Settings with the settings of other browsers.
6. Click on OK to save the changes you made.

Method 8. Change the Enhanced Tracking Protection to Standard

Firefox uses Enhanced Tracking Protection to protect user privacy, which can impact browser performance. While it helps block online threats and shady scripts, it may also cause issues. Using the Standard protection level is recommended as it rarely causes problems, unlike the Strict protection level that overprotects the browser and may prevent it from loading some pages with no threats. If you recently changed the protection level and pages are not loading, consider changing it back to default by following these steps:

1. Click on the three horizontal lines in the top-right corner and navigate to Settings.

2. Go to Privacy & Security in the left sidebar.

3. Change Enhanced Tracking Protection from Strict to Standard.

4. Click Reload All Tabs to see the change take effect.

Method 9. Check Network Connection

If you’re experiencing difficulty loading pages on your browser, it’s worth checking your internet connectivity, as the browser won’t be able to load any pages without it. Therefore, ensure that your network is functioning correctly before proceeding. If your network is not working, try switching to a wired connection via Ethernet, or if you’re already connected via Ethernet, consider switching to a wireless connection via Wi-Fi.

Method 10. Run a System Malware Scan

To determine if the problem with Firefox is caused by malware hidden in Windows, you can run a malware scan. If adjusting your browser settings has not resolved the issue, this quick scan can help diagnose and fix the problem.

To run a malware scan, follow these steps:

1. Open Windows Settings and select Update & Security.

2. Choose Windows Security on the left-hand sidebar.

3. Under Protection areas, click on Virus & threat protection.

4. Select the Scan options and choose the scan you prefer.

5. Click Scan Now to begin the scan.

6. Wait for the scan to complete, then restart the Firefox browser. If the problem persists, consider reinstalling Firefox.
