Have started seeing diamonds with question marks on FireFox (and Chrome); changed encoding, made no difference.

Both FireFox and Google Chrome (but not Internet Explorer) have been showing black diamonds with question marks in them for some time. It's not an encoding issue, as changing character encoding doesn't work. I don't know what caused it, as it all of a sudden started out of the blue. My network.http. in about:config are all default. I've tried scanning for malware, including in safe mode with the internet disconnected. Nothing has made a difference. Please help me, as this problem is incredibly hard to Google and I have no idea what to do.

Can you spot a pattern as to which fonts are involved? Sometimes font files become corrupted or browsers substitute other similarly named fonts.

The FontInfo extension adds a right-click context menu item to see what font Firefox actually is using for a selection of text: That might help in isolating the problem.

Hello FedUpFrustrated

See cor-el's reply :

thank you

Can you post a link to a web page where you see these diamonds and possibly attach a screenshot?

Which encoding settings did you try?

A diamond with a '?' usually indicates that a character is missing in the font that is used on a website or the wrong encoding is used. You can also get the '?' on websites that use an 8 bit encoding like ISO-8859-1 or an encoding like Windows-1252.

Screen shot:

As for encodings, I've tried switching from Unicode(UTF-8) to Western(ISO-8859-1) and and to every one with Western, Japanese and Korean in its name out of desperation.

The server sends the page in your link as Unicode (UTF-8) and that works for me.

This can be a problem with the font that is used to display the text.

You can use this extension to see which fonts are used for text that is selected (right-click: "Show fonts in selection").

You can try different default fonts and temporarily disable website fonts to test the selected default font.

  • Firefox/Tools > Options > Content : Fonts & Colors > Advanced
  • [ ] "Allow pages to choose their own fonts, instead of my selections above"

The more I look at your image, the more broken it looks. You can see parts of HTML tags where they should not be visible, such as the /span> in the top bar and after the date (in red); the drop-down that has /option>; and in the video descriptions where you see strong or href=.

Something is corrupting the page, maybe an extension, or proxy/filter service, or security software?

To rule out an extension, you could try Firefox's Safe Mode. That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

A website I visited through Firefox shows interminable little black diamond-shaped diagrams with a white question mark inside. Using IA and Chrome they do not appear on that website. They do not seem to appear on other websites through Firefox. Is it the fault of the visited website or does Firefox have a bug. I'm no good with complicated answers such as I have seen here.

Hi kadona

Can you post a link to a publicly accessible page that doesn't require authentication (signing on)?

Did you check which encoding is used (Firefox > Web Developer > Encoding)?

You usually see the diamonds if there is a wrong encoding used like UTF-8 instead of Western encoding that doesn't include the character.

Also make sure that the default encoding is Western (ISO-8859-1)

  • Tools > Options > Content : Fonts & Colors > Advanced > Default Character Encoding

I'm sorry, but I cannot understand a word of what you have said. It is like a foreign language :) But thank you for trying. I have only seen these things on the same website of which I am a member. -never anywhere else. I use Firefox a lot. But when I accessed that website through two other browsers, just to see, the black diamonds did not appear - only through firefox. I do not experience this phenomenon anywhere else when I use firefox.

Did you try to go to "Firefox menu button > Web Developer > Character Encoding" or "View > Character Encoding" if the menu bar is shown?

Which encoding is mentioned in Tools > Page Info > General?

  • Press the F10 key or tap the Alt key to bring up the hidden "Menu Bar" temporarily.

Hi kadona, do you think a volunteer would see the same problem visiting a page that doesn't require a login? If so, you could post the URL.

I went in again as a member, using Firefox as I had done previously, and there were no black diamonds. Bit of a mystery! I was about to post the url for you to look at but decided to take another look first. And they were not there!

Sounds like a problem with cache corruption that fixed it self (data may have expired).

I got on to 'tools', found Web Developer, but there was no 'Character Encoding' or the alternative there at all.

I saw it again through Firefox - from the same website, but not the same page as before.

he Council of Islamic Organizations of Greater Chicago supports the idea.

�I think it will open up doors,� said Janaan Hashim, a spokeswoman for the group representing more than 400,000 Muslim Americans in the Chicago area. �Language is a man-made limitation. I think what God cares about is how we fulfill our purpose in life.�

The nation�s largest Catholic civil rights group says Catholics won't get behind the proposal.

�Bishop Martinus �Tiny� Muskens can pray to �Allah� all he wants, but only addlepated Catholics will follow his lead,� Bill Donohue, president of the Catholic League for Religious and Civil Rights, said in a statement. �It is not a good sign when members of the Catholic hierarchy indulge in a fawning exchange with Muslims, or those of any other religion.�

Hi kadona, the diamonds are characters that are not compatible with UTF-8 (Unicode) encoding. You can get those characters to appear by switching to ISO-8859-1 encoding.

Hard to explain, but easy to do.

View menu > Character Encoding > Western (ISO-8859-1)

If you use the compact two-column menu (orange Firefox button), you can tap the Alt key or press the F10 key to reveal the classic menu bar with the View menu.

I wish I knew what you mean. For the life of me I cannot find the 'encoding' word anywhere in tools. I see the web Developer there, but it leads nowhere. I don't know what you mean by the 'compact two-column menu' etc. or the orange firefox button.

When I click on Firefox it displays the google search page...there is no orange button. I pressed each of the keys you say to press, but nothing happens.

I'm totally illiterate with regard to these matters. Sorry to be so dumb!

Hi kadona, Firefox on Windows has a choice of two different menu systems.

  • If you have the classic menu bar -- File, Edit, View, History, etc. -- look on the View menu for "Character Encoding".
  • If you do not have that bar, tap the Alt key or press the F10 key to display that menu bar.

Hi kadona, if you can't get the menu bar to appear, make sure you are not using Full Screen mode. The F11 key switches between Full Screen and Normal views.

AH! That's what I needed to know. Yes, I have the 'View' button. The encoding that is bulletted is Unicode (UTF-8). So would you say that is OK? .....that it cannot be anything wrong on my computer? That it must be something wrong with the website where it appeared?
