Hope this article will help you Firefox can't load websites but other browsers can .

Thanks.

Hi thomasgreatheart, if the above doesn't help, could you describe in more detail what happens when you try to open that address? For example:

• error message -- what does it say? feel free to copy/paste
• blank page
• blank page after a login page
• partial load, like unstyled HTML text, or blank regions within the page
• something else

The web address appears in the address bar at top of page. The rest of the page is totally blank. No error messages or anything else.

The web address appears in the address bar at top of page. The rest of the page is totally blank. No error messages or anything else.

Could you open the Network Monitor tool in the lower part of that tab -- either:

• "3-bar" menu button > Web Developer > Network
• (menu bar) Tools > Web Developer > Network
• (Windows) Ctrl+Shift+e

Then click in the address bar and press Enter to trigger a reload, or press Ctrl+Shift+r. In the Network Monitor, Firefox should start listing all the files it is requesting, along with information about whether the request was successful -- usually a 200 or 304 in the left column. Do you see any activity there?

Here's what I got:

Status: 200 Method: GET Domain: reader.epoch.cloud Initiator: document Type: html Transferred: 750 B Size: 920 B 0 ms: 220 ms

1 request 920 B / 750 B transferred Finish: 220 ms DOMContentLoaded: 763 ms load: 999 ms

920 bytes is not very many characters but you should see at least a little something, unless it's just a bunch of instructions to move on to the next thing.

What normally happens with this address: does it redirect to another page, or login, etc.?

You may want to make sure the redirect block is turned off:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste access and pause while the list is filtered

(3) If the accessibility.blockautorefresh preference has a value of true, double-click it to restore the default value of false

What normally happens with this address: does it redirect to another page, or login, etc.?

It just opens the webpage which is a digital online newspaper -- no login, no redirect, etc.

I have no issue opening ANY other webpage, so don't know why the redirect block would have anything to do with it...? But I am not that knowledgeable about it, so ?

I see why the page only has 920 bytes, it basically is a frame which loads the site from a different server.

What if you right-click in the center of the blank page, then expand This Frame, then click Reload Frame. Does anything load?

Tried it -- page remains blank

Could a blocker be coming into play?

Double-check content blockers: Firefox's Content Blocking/Tracking Protection feature, and extensions that counter ads and tracking, may break websites that embed third party content (meaning, from a secondary server).

(A) Do you see a purple shield icon toward the left end of the address bar, near the lock icon? More info on managing the Tracking Protection feature in this article: Enhanced Tracking Protection in Firefox for desktop (before Firefox 70: Content Blocking).

(B) Extensions such as Adblock Plus, Blur, Disconnect, DuckDuckGo Privacy Essentials, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix should provide toolbar buttons to manage blocked content in a page. There may or may not be a number on the icon indicating the number of blocked items; you may need to click the button to see what's going on and test whether you need to make an exception for this site.

Testing in Firefox's Safe Mode: In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.)

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" Help > Restart with Add-ons Disabled
• (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

I restarted Firefox in safe mode, and the website (e-newspaper) loaded. So how do we figure out which add-ons are blocking webpage?

Do you have content blocking extensions ?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

• make sure your extensions and filters are updated to the latest version
• https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

Firefox shows a blueish highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content. You can click shield icon for more detail and possibly disable the protection. You can check in the Web Console what content is blocked.

• "3-bar" menu button or Tools -> Web Developer
• https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop

If it works in Safe Mode and in normal mode with all extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) disabled then try to find which extension is causing the problem by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via one of these:

• "3-bar" menu button -> Exit (Power button)
• Windows: File -> Exit
• Mac: Firefox -> Quit Firefox
• Linux: File -> Quit

Some of your extensions probably block content intentionally, whether for security, privacy, or simply annoyance-related reasons. Those are all suspects. If they have toolbar buttons, you can check them to see whether they have an option to make an exception for the current page, and whether that allows the frame to load. If they have an all-or-nothing design, you may need to individually disable them on the Add-ons page for testing.

Thanks, but I don't really know what "extensions" are, or how to check them -- can you give more specific instructions for dummies?

Did you read the article or is that still not clear ?

I disabled DuckDuckGo privacy essentials, and the website loads, however, I don't see a way to make an exception for this webpage in privacy essentials add-on.

Yes, unfortunately they don't provide a lot of controls. Take it or leave it, I guess?

Okay, well thank you for all your help - maybe I will try reaching out to DuckDuckGo and see what they suggest.
