From the discussion here:

Under WinXP and Vista, some pages have all of their text bolded.

The regression range that one of the forum-goers found was 032705 - 032805

Is was suggested this was a regression possibly caused by Bug 424945.

Reproducible: Always

Steps to Reproduce:
1. Go to Google or Wikipedia
Actual Results:  
All fonts are bold

Expected Results:  
Fonts should be bold where appropriate

What are your default font settings?  It's weird that b4 has all that text in italics.

I'm one of the two from the forum that this bug is effecting. My default font settings are just that, default, this happens on a clean profile so they must be default. Unless you're talking about Windows settings in which case I have no idea. I'm also the one that found the regression range of 032705 - 032805 mentioned in the first post.

I have had this happen to me before and I have fixed this numerous times. It usually happens after I install Office 2007 on my Vista machine running SP1. It's not a problem within Firefox but a problem with Windows in general. If you use Opera then instead of Google and Wikipedia being bold it will be italic instead. (go figure). You can use this registry fix to reset Vista's default fonts.
http://www.zshare.net/download/1036857372145d6b/ . Apply that registry fix, reboot and report back :)

If you have applied that .reg fix you might find that some fonts are missing. Apply this fix to sort that out.

Actually, on my system(Vista SP1), if look here in the registry

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]

The key arial is missing,

just add a string value "Arial (TrueType)"="arial.ttf"


solve the Firefox bold problem and all the italic problem in wordpad, opera, IE7...

I can confirm this bug. It happens here on Firefox 3.0 and Windows XP. The registry fix doesn't help me too.
I'm also seeing this in SeaMonkey 2.0a1pre on WinXP for some time now. For the regression window: This bug appeared to me for the first time when I added myself to this bug, that was on 20th of may. 

I have to add that this doesn't seem to happen on all pages, and sometimes only parts of a page are bold. Especially on http://www.heise.de/ i can see this very often.
Ever confirmed: true

I should add this not happen on text where fonts are declared by CSS. Only default font style is affected by this bug. For example I can't use SquirrelMail at all because all 'unread' and 'read' mails are bold displayed.

Guys, the banter on this bug is not appreciated. You've already said it doesn't work and that is all you need to say, unless you have something to contribute towards fixing it.

Have you checked your default font settings to make sure they are correct?
Preferences -> Content -> Fonts and Colors

Which of the registry fixes did you apply? There are 2 of them. Also, these only account for a small handful of fonts. It could be other fonts that are giving you problems.

The bolded fonts on http://heise.de (on the sidebars) appear to be there on purpose (declared in CSS). For example, the first group of links in the navigation section have a font-weight of 700.

But I'm not seeing any of this behavior at all (on either XP or Vista, nor Linux), so I'm betting that it is something wrong with your system config/fonts.

Matthew, I checked my default font settings and everything's corret/normal. I didn't have this problem at Firefox 2, but now I have it on Firefox 3.

I really believe the problem is with Firefox. Incompatibility with something that obviously I don't know what, otherwise I would fix it!
I don't have this problem at Opera, Flock, Safari, IE, Firefox 2......
..... only at Firefox 3!

That's why I think it's a bug. And I do need it to be fixed, so than I can completely LOVE this new version.

I'm not a geek or pc expert. If someone could help me with a simples step-by-step, I would be very glad and thankful.

Guys, its not a firefox/moz bug persay, the font glyph outlines and some things get stuck in some cache, at least on windows, and the cache isn't invalidated and is interpreted differently after an upgrade/install of ff3 where ff2 had been before. long story short, go to Options -> Content -> Fonts & Colors, change font away from Times New Roman (or what have you), to another font, hit OK, reopen the dialog and change it back to what it was before, it ends up invalidating whatever cache was causing the problem. if there IS a bug here, it is in not marking the cache invalid between version changes (looking at cairo here)

Comment 26

This is happening to me with the font Garamond. The fixes did not work for me, and I applied both. I did as you said by changing the font in hopes of refreshing the cache, but no that didn't work for me either.

> Guys, its not a firefox/moz bug

Yeah sure, it's not a bug it's a feature.  I've heard that firefox developers are able fix every bug in few days. This bug has few months and now we hear that it is not a bug.

I have no problem with fonts on my system. Only Fierefox 3.0 has problem. I'm dissapointed how firefox's developers treat users.

Comment 28

I did not misrepresent myself as a developer, but as a person who had ignorantly opened a bug just like this one, only to discover shortly after that it wasn't a bug with FF, and changing the fonts as described fixed it. You are right, there are no problems with your fonts. I personally think trolling bugs is a bit offtopic. (as for the registry fixes, I didn't try any of them, they seemed arbitrary and assumed a problem existed that wasn't the case on either of the machines exhibiting the problem)

This time changing fonts doesn't help. It was first thing I've tried before I add my comments here.

I'm sorry, a few of you have said not discuss this bug, since it is not doing anything for the bug. But no one has been assigned this bug, is it possible for someone to contact mozilla about this? I have downgraded to firefox 2.x until it is fixed. This is a serious bug, a lot of site have bold text, it is really really annoying, and I can't believe anyone hasn't gotten assigned to fix this.

I'd just like to add that I am encountering the same problem since the upgrade to Firefox 3.0 (on Windows XP). I have tried what Josh suggested in comment #25, but unfortunately it didn't change anything. I would rather avoid doing any changes to the registry I am not mastering and will thus downgrade to Firefox 2.x.
Thanks to any of you for efforts: Firefox 3.0 works just great on my Mac...

Also I have this annoying bug with firefox 3.0 on Windows XP.

Zachary & Konrad: you've made your point, if you don't have any data to add to this bug report, please be quiet. Adding comments like the ones you have been adding is *not* helpful.

Stuart, could you please look into this and perhaps guide these helpful reporters into giving you information that can track this issue down? It definitely seems to be affecting some people, and it would be good if we could figure out what's causing it, be it on our end or some bizarre setting that got flipping in Windows.

The regression range implicates the use of the font cache.

I'm having the same problem.  Windows XP w/FF3, running on a Gateway Laptop.

My laptop has been going very slow so I've been messing around with the Startup Logon stuff to speed up my logins.  I unchecked a few things that are 'useless' to me, including a few Intel graphic startup items.  Doing a search on them tho revealed they are just taskbar and hotkey items, things I don't use anyway.

I was wondering if this contributed to this bug, but I doubt it.  It's weird coz CNN.COM for example looks fine, but eBay or Google appears bold!  The Mozilla startpage is also bold.

Because cnn.com has all fonts defined by css.

You can check this simple html:

<p>It shoud be normal text not bold</p>
<p><strong>This is real bold</strong></p>

In Fierefox 3.0 first paragraph is displayed as bold.

Okay guys I fixed my Bold problem, but I just don't exactly know how..  

Here's the background info:
When I first installed FF3 I didn't notice any bold fonts, but then for some reason a few days later I noticed the bold issue.  I didn't change any settings anywhere and it still went bold on me.

I opened Internet Explorer 7 to see if it was just a FF issue, and all fonts were Italic!  What the hell?

So I uninstalled FF3 and went back to FF2, and all fonts were Italic now!  I went back to FF3 and all fonts were Bold again.

I started searching forums after posting the bug here, and I saw people were talking about fonts being reassigned or deleted, thus defaulting to the bold and italic versions.

I went thru my C:\windows\fonts directory and found they were all there.  I then went thru the Control Panel\Fonts and opened each of the versions of Ariel, Veranda and Tahoma, just to see if they were reassigned, and they were OK.  

**BUT** --  After I did this, I launched Firefox 3 all fonts were fixed.  I launched IE7, all fonts were fixed!  So I guess maybe fonts were reassigned and actually opening them up under control panel reassigned them somehow?

I don't know, but it fixed it for me.  Good luck guys!

Hey, Slawek, this worked for me, too! Thanks a lot!
I had the bold font problem with FF3 on Windows XP (don't have IE7). After opening the font files in c:\Windows\Fonts for Arial, Verdana, Tahoma and Times New Roman, and reopening the browser, everything went back to normal (at least gmail and igoogle).
No clue why, though.

Hi Mike

Can you guide me step by step how to do it...

Comment 40

11 years ago
I really have no idea of what is really going on. Some mess with Windows font management, I guess. Maybe during the FF3 installation process? Maybe some of the Mozilla folks have an idea on how to narrow this problem down?

Anyway, here is what I did according to Slawek's comment in more detail:
1. open windows explorer, go to folder C:\WINDOWS\Fonts
2. open and close some of the font files which are in there, without doing anything special. In my case I did this for all variations of Arial, Verdana, Tahoma and Times New Roman.
3. reopen Firefox.
Since then, the sites where I had observed the problem work fine again (bugzilla.mozilla.org, gmail, igoogle etc.), even after a complete reboot of the OS.

Regards, and many thanks to all those investing their time and energy in this great software project. You do a great job!
Hi all,

I have a fresh installation of Windows XP with SP3. Didn't install Firefox 2 or another browser. Only installed system drivers, Acrobat Reader, MS Visual Studio & MS SQL Server 2005. But I suffer the same problem described. What I think is, based on what I see on my new XP installation, the problem is not related to an application installation that could mess with the fonts for I still have few apps in my PC.

I had this problem occur for me as well.  I was using the alphas, betas, rcs and finally the final version of firefox and this only happened to me this weekend.  It was working fine, then I had to update some extensions.  After I restarted the browser, I closed the updates window (otherwise I would have noted them down) and everything was bolded.

I just opened up all my fonts, and it seems to have fixed the problem.
Firefox 3 started rendering all of my Arial fonts in bold about 2 days after install. No extensions/add-ons but I did uninstall some windows apps in between.

__The Fix__
I went to the windows/xp fonts folder, moved all the Arial fonts into a backup folder then re-added just Arial True Type (Arial TT) back to the fonts folder.

Restarted FF3 and the rendering is back to normal.

It worked for me. Thank you, Cyber!
Ok, it worked. But I didn't have an Arial True Type here. So my Firefox is getting another font to replace.

Could you put your Arial TT in a download service, Cyber?
So then I'll use yours (and also all the people at this forum).
Thanks in advance!

I'm having Win Vista Home Basic,

I've removed and replaced Arial TT font. Issue seems to be fixed... and fonts have become normal which were bold earlier... but there are something wrong with Bold Fonts on same page.. it doesn't look as clear like it should. 

When I again try to install Arial Bold fonts, all webpages fonts become bolder again.

I temporarily deleted all the bold Garamond fonts and instead my text is showing up italic instead. Well that's just great... but still not exactly what I want to have happen.

Reinstalling the fonts didn't work.

Wait, nevermind... (sorry to post again - if I could edit my comment, I would)... I hadn't reinstalled Garamond Antiqua. Now that I have the page looks normal again though the only way I can keep from seeing the page in all bold is by deleting the bold fonts.

I've deleted all arial fonts from my Windows XP and replaced them by arial from Windows 2000. It fixed my problems with Firefox 3.0.

Firefox 2.x.x and any other programs have not any problems with previous arial fonts. I have no idea why FF 3.0 don't like them.

I fixed my problem!! All pages which used Verdana font were bold at Firefox and in Italic at IE, so when looked for my verdana font in font folder "windows/fonts", there were only verdana bold and verdana italic fonts. Then, I installed the verdana font and all pages back to normal.

Sorry my bad English, I hope help you all. Maybe the problem is some font that isn't instaled.

Thanks for all that tried help us :)

I'm still having this problem and I hoooped with the new release of FF that came out it would be fixed but nope... Would anyone be kind enough to send me their copies of Garamond? adelyn.xx@gmail.com Maybe that would fix my problem since reinstalling fonts seems to do the trick for some.
I had this problem but I also had another one: when I logged in into Windows, the password field showed blank squares instead of the expected bullet characters. I was told to replace some MS Fonts, so I looked for the fonts installers and found them in http://web.nickshanks.com/typography/corefonts. Replacing the fonts with those helped me fix the problem, but as a side effect it solved my Firefox problem. Hope this will help you too!

Yo tenía este mismo problema pero además tenía otro distinto: al iniciar mi sesión de Windows, los caracteres del campo de contraseña eran cuadrados blancos en vez de los puntos normales. Se me dijo que reemplazara algunas fuentes de MS, y al buscar los instaladores de las mismas los encontré en http://web.nickshanks.com/typography/corefonts. Reemplazar las fuentes con estas otras me resolvió el problema, pero como efecto secundario se me solucionó el tema del Firefox. Espero que esto también les sirva!
(In reply to comment #58)
The link I sent (http://web.nickshanks.com/typography/corefonts) is not working today. So I looked for and found another link with the font definitions: http://prdownloads.sourceforge.net/corefonts. Select package "the
fonts", and there you are. If you still can't find the files, please google for "arial32.exe andale32.exe" (don't write the "") and you will find some other sites where you can download the files from.
Hope to be helpful!
Doesn't really meet the "wanted" criteria (security, stability, regression from maintenance release) for 1.9.0.x. However, we'll look at a reviewed and baked patch.

I've had the same issue on a newly setup System using Win XP Pro SP3 and Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv: Gecko/2009021910 Firefox/3.0.7 (.NET CLR 3.5.30729) - Build ID: 2009021910

A webpage I was working on had a bold Arial font in a paragraph that was supposed to be regular font-weight. After disabling the font-family CSS-declaration via Firebug everything was working as supposed to, so the rest of the CSS seems to be OK.

Looking into the registry, the entry for arial was the following:
"Arial (TrueType)"="Arial.TTF"
while the according file is registered "arial.ttf" in the file system.

So I tried changing the registry value to the correct case (which should not be necessary on Windows systems):
"Arial (TrueType)"="arial.ttf"

After rebooting the page displays just fine, so maybe this is an issue with strict case-sensitivity for fonts registered on Windows systems?

Without being able to check it to the last bit, it seems that this only occurs in specific cases, i.e. maybe when the last rendered paragraph is explicitely bold. Maybe there is an case-sensitive call for the appropriate font, that if it fails, falls back to the last used or another random weight of the font?

It's odd that this report is still open after all this time, especially since bug 424945 that this one blocks is marked fixed.

Could some of the people who initially reported the problem — and haven't modified the registry or their font collection — re-test in the latest version of Firefox?
