Firefox has always been at the forefront of offering a safe and secure surfing experience. Look no farther than its Enhanced Tracking Protection, which improves its position in the privacy arena.

Some users receive a Firefox not working‘ message, while others receive a Connection Has Been Timed Out problem. If you’re on the same page as me, then this tutorial is for you. Listed below are many techniques for resolving the Firefox not loading pages problem.

Troubleshooting and diagnosing Firefox issues

Restart your PC as follows:

Sometimes difficulties can be Firefox not responding resolved by just restarting your computer and relaunching Firefox.

Clear your cache and cookies:

Many issues with web page loading can be remedied by removing Firefox’s cookies and cache. More information may be found at Clear cookies and site data in Firefox and How to clear the Firefox cache. To erase both your cookies and the Firefox cache at the same time, follow these steps:

  •     To open the menu panel, click the Fx89menuButton menu button.
  •     From the Time Range to Clear drop-down option, select Everything.
  •     Select both Cookies and Cache from the drop-down menus. Check that no additional things that you want to keep are chosen.
  •     Click the OK button.

Restart Firefox in Troubleshoot Mode as follows:

Firefox Troubleshoot Mode is a diagnostic mode that, among other things, disables extensions, uses the default theme, disables hardware acceleration, and uses the default toolbar settings (see this article for details). To launch Firefox in Troubleshoot Mode, follow these steps:

  •     Click the Fx57menu button, then Help, then Troubleshoot Mode… and then click Restart in the dialogue box labelled Restart Firefox in Troubleshoot Mode?
  •     Note: You can also launch Firefox in Troubleshoot Mode by holding down the option key when you launch it.
  •     Click Open in the next Open Firefox in Troubleshoot Mode? dialogue.
  •     While in Troubleshoot Mode, check to see if your problem is still occurring.

Install Firefox again:

A bug with one of the Firefox programme files might cause certain Firefox difficulties. To delete and reinstall Firefox, follow these procedures. Because your Firefox profile data (such as bookmarks and passwords) is saved in a different place, this method will not erase it.

  • hosts the most recent official version of Firefox.
  •     Quit Firefox: Select Quit Firefox from the Firefox menu at the top of the screen.
  •     Uninstall Firefox from your computer by going to the Finder’s Applications folder and dragging the Firefox application to the Trash.
  •     Reinstall Firefox – for details, see How to Download and Install Firefox on a Mac.
  •     Start Firefox again and check to see whether your problem has been resolved. If it hasn’t already

Extensions should be disabled:

Third-party add-ons, particularly those using JavaScripts or modifying in-page elements, have a history of disrupting page components, resulting in their inability to load correctly.

It would be helpful if you launched the browser in safe mode to confirm if this is the case this time. This will disable all extensions, and you may then proceed as desired.

  •     Start the Mozilla Firefox web browser.
  •     Click on the horizontal three-bar icon menu in the upper right corner.
  •     Choose the Help > Troubleshoot Mode option.

In the confirmation dialogue box, click Restart. The browser will now enter Safe Mode. If you can browse the websites in this mode, the problem was caused by third-party add-ons.

Turn off DNS prefetching:

A DNS Prefetch automatically retrieves the resources needed for a DNS lookup that the browser may request. So, if the browser does issue such a request, the DNS query will have already occurred.

As a result, the browser would load that site more quickly. However, in certain cases, this prefetch approach may cause websites to malfunction or erroneous settings to load. As a consequence, it would be ideal if you thought about removing this functionality and then observing the effects.

To deactivate DNS prefetching in Firefox, follow these steps:

  •     Launch Mozilla Firefox and type about: config into the address box.
  •     Accept the Risk and Continue by clicking the Accept the Risk and Continue button.
  •     Type “.network.DNS.disablePrefetch” into the search field and click Enter.
  •     To change the value of the toggle button from False to True, click on it at the far right.
  •     Now, refresh the site to see if it resolves the Firefox not loading pages issue.
  •     As previously stated, the DNS Prefetch approach does speed up site loading. However, if they interfere with the usual loading of the site, the few precious seconds saved won’t be worth much.

As a result, it is preferable to leave this function inactive and pursue a more balanced approach overall.

Make a new Firefox profile by following these steps:

Files in your Firefox profile folder that relate to critical information that a Firefox Refresh does not destroy (such as bookmarks and browsing history) may sometimes be the source of the problem. You may make a new profile that does not contain any of your previous Firefox data. For more information, see the Profile Manager – Create, delete, or swap Firefox profiles article.

Alternative solutions:

If you’ve exhausted all of your troubleshooting options and are still experiencing issues, here are some further options to consider:

Examine the browser’s internals:

The Firefox Task Manager (about: performance page) allows you to identify which tabs or addons are causing Firefox to slow down. The telemetry data shared with Mozilla (about: telemetry page) includes extensive information on performance, hardware, use, and customization.

Examine for malware:

Malware (short for “malicious software”) may wreak havoc on Firefox.
