Firefox not loading web pages

Firefox currently has an issue that prevents certain pages or page elements from loading under certain circumstances. Mozilla included the known problem in the release notes for Firefox, indicating that certain “web pages or page elements that use dynamic JavaScript will not load.”

The release notes include a link to a support article on the Mozilla site that provides an alternative solution to the problem and additional context.

Depending on the article, sites like YouTube or Facebook that use dynamic JavaScript may be affected. Mozilla has created a test page for this problem that Firefox users can open in their web browser to see if their version of the browser is affected.


If you see “good: fully functional,” Firefox should not be affected by the problem; if you see something else, such as “investigate.” If it doesn’t go away, “things break unexpectedly,” it might be affected, and you should use a workaround to mitigate the problem until Mozilla releases a permanent fix.

The bug report on Mozilla’s Bugzilla bug tracking site says that the problem affects old profiles, but not newly created ones. The problem appears to be caused by a new storage implementation in Firefox, which Mozilla calls LSNG (Local Storage Next Generation).

Mozilla has confirmed an issue affecting Firefox users after upgrading to the latest version 70.0, preventing websites or page elements that use dynamic JavaScript from loading.

This known problem was added to the Firefox 70.0 release and is known to affect various websites, including but not limited to YouTube or Facebook, which do not load properly.

According to a bug report describing the problem on the Mozilla bug tracker, “Site banners are displayed, but site content does not load correctly and displays only the blank part of the page where the details should be.”

“Facebook, for example, displays the top line, but no feed content. The “Asda” page does not display order information. Two survey pages don’t display screen content.”

Problem Overview: Firefox won’t load pages


The fact that Firefox does not load pages is a problem that many Firefox browser users face. There are many variations of this problem. Sometimes Firefox fails to load a single page, sometimes multiple pages, and sometimes a web page. The problem may be related to the security aspect of the website. There may also be a problem with your Internet connection.

You may need to restart your browser if it has been in use for an extended period of time. Some problems may also be related to Firefox browser settings. Let’s start with solving the problem of the Firefox browser not loading pages.

The browser is not displaying images on the page

If you don’t see pictures at all, the problem is probably on your end, not the site you’re visiting. Specifically, it could be caused by browser settings or incompatibilities. Before you continue, make sure your Internet connection works by visiting a Web site you’ve never visited before.

The browser displays images, but some of them are missing

If only some images are missing, it’s usually a problem with the Web site you’re visiting, not with your computer or browser. In particular, some images may not load for one or more of the following reasons.

To solve the problem of web pages not loading and displaying correctly in Firefox

The problem of web pages not displaying correctly occurs in all browsers. If you encounter this problem, one of the following suggestions will surely help you solve it.

Clear cookies and cache for Firefox browser

The purpose of cache files is to allow web pages to load faster when you try to open the same web page. These files are temporarily stored on your system’s hard drive. However, if you’re having trouble loading and displaying a web page, the first thing to do is clear your cookies and cache. To do this, follow these steps:

  1. Click on the “Library” button in the upper right corner of the screen. It is represented by 3 vertical lines.
  2. Select History > Clear Last History. Check the “Cookies and Cache” box and click “Clear Now“.
  3. Reboot the system when you’re done.
  4. If the files in the cache are deleted, the system will rebuild them when you re-open the site.

Resetting web page scaling

Although most Web sites adapt to the scale of the screen, some may not work as expected. If this is the case, it is recommended that you reset the screen size to 100%. A quick key combination to reset the screen size to 100% is CTRL + 0.

It should be noted that the Firefox browser zoom is changed through the menu located in the upper right corner of the browser window (indicated by three vertical lines).

Resetting the minimum font size

Some web pages have display problems when the minimum font size is not set to no. Some extensions and plug-ins have been known to cause this change.

Follow these steps to solve this problem:

  1. Type about:preferences in the address bar and press the Enter key.
  2. Scroll down to “Fonts and Colors” and click “Advanced“.
  3. Change the Minimum Font Size to None.
  4. Restart Firefox and try reloading the web page.

Resetting the web page style

You may have set the web page style to “No style”. In this situation, you may encounter the problem discussed. This is because no default style has been specified for web pages. You can change it to the main page style.

You can solve the problem as follows:

  1. Press ALT while holding the Firefox browser open. Then the traditional Firefox menu will appear at the top of the window.
  2. Choose View > Page Style > Main Page Style.
  3. Restart the Firefox browser and see if the problem is fixed or not.

Make sure JavaScript is not blocked

When JavaScript is blocked, some parts of the page will not load correctly in the Firefox browser. You may not intend to block JavaScript, but some extensions such as NoScript and some security programs can block it.

To limit the problem, please temporarily disable browser extensions that are known to block scripts and security software.
If this solves the problem, you can add Firefox as an exception to the security software whitelist.

Make sure the system clock is set correctly

Websites use certificates for verification. However, the browser and websites judge the date and time according to the system clock. If the system clock is set to the wrong date (much older or later), the site will not load properly. Check the date and time on the clock in the lower right corner of the screen. If they are wrong, please correct the date and time.

Disable hardware acceleration

Some drivers do not display web content correctly when hardware acceleration is enabled.
In this situation, you might consider disabling hardware acceleration to access web pages.

Reset Firefox

You can reset Firefox and see if that helps.

Report website

Try opening the site on a different system. Also, try opening it with a different browser on a different system.

If the site doesn’t work in both cases, you can report the problem to the site owner.
