Is the pref gfx.downloadable_fonts.enabled set to true on the about:config page?

value set to true @cor-el i've tried toggling it back and forward (true/false), yet nothing

You may need to close and restart Firefox after you have toggled the pref to true.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

• Don't make any changes on the Safe mode start window.

See:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

"You may need to close and restart Firefox after you have toggled the pref to true. "

have tried that a couple of times, still google fonts look the same

safe mode was promisng but i got same issue with google fonts

i should mention that im running firefox 4 beta and doesnt seem like there is a native way of enabling default theme during safe mode, i have it disabled. going to try a random theme off firefox addons page next.

having tried another theme, no luck

I'm not sure this will help, but you could disable the hardware acceleration: Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available" . Trying won't hurt at least.

thanks for the tip about hardware acceleration yet no luck

Do you see a request for those fonts if you install the Live HTTP Headers extension and check the requets and response header?s

• Live Http Headers: http://livehttpheaders.mozdev.org/

I was having the exact same problem as originally stated. I'm using Firefox 3.6.13 on OS 10.6.6 and was basically just getting the fonts to render as Times New Roman. I enabled Live HTTP headers and it dawned on me that my network Proxy was the issue. I turned this off - went back to Wireless and BINGO - webfonts work perfectly in Firefox! For whatever reason my Proxy was blocking them. Hope this helps some of you.

for instance:

i m not exactly sure of how liveheaders extension would help my issue, i posted a pastebin above of http header returning status 304, something that was suspicious to me

i have mentioned in my first post that Google Chrome recongizes and displays Google Fonts just fine.

I have took measures to disable "proxy behavior" by shutting down firewall client (zonealarm), disabling spywareblaster adware protection and restotring windows HOSTS file. I have also tried connecting this here laptop to another network with no luck for google fonts/firefox issue

Having a multiboot ubuntu installation i have no problem loading google fonts via ubuntu os/fiefox/same laptop

ive just noticed the weirdest thing, "cyrillic" web fonts are actually displaying as they meant to: http://www.google.com/webfonts?subset=cyrillic

yet Greek, Khmer, Latin are remaining as before, for this machine

Why behind a Proxy Google fonts rendering are blocked on firefox? ex.: http://www.google.com/webfonts/

There was a solution server or code side?

• Bug 627616 – font-face fonts not loaded over authenticating proxy

(please do not comment in bug reports; you can vote instead)

Having installed Firefox 4 (deleted existing pereferences and settings). The problem remains. Yet Cyrillic google web fonts are display just fine.

I should mention that I'm running a custom version of Windows XP with a lot of services removed and a lot of not so often to use stuff wiped out in order to get max speed/max space removed. Could that be a problem?Is there any Windows XP service/application that Firefox relies on to render Google Web Fonts properly? Like i mentioned before as well, Google Chrome renders these fonts just fine.

Maybe its a regional setting, I have tried switching keyboard layout and switching on advanced text services.

now running firefox 4.0 stable issue remains

someone suggested it, yet i disregarded it as stupid. little did i know http://www.google.com/webfonts will display any font i actuallly have installed on the local computer.

for example download font Sunshiney http://www.google.com/webfonts/family?family=Sunshiney&subset=latin#download

install it locally, for ie C:\windows\fonts

and the next visit to google web fonts directory will that have that font displayed correctly. is there deeper permission then

Options > Fonts Allow pages to choose their own fonts, instead of my selections above as i have that checkboxed.

Google Web Fonts DISPLAY works, but PRINTING does not.

I found a somewhat similar solution in about:config to try enabling. (Mine was off/false by default.) print.print_downloadfonts --> Set to true.

However, I tried this and although I can definitely see the fonts, they *print out* as default fonts (_serif or _sans). Google's Web Fonts work on every other browser/OS combination I can think of (Mac, PC, Linux <--> Chrome, IE, Safari)

Using Mac OS X 10.5.8 and Firefox 4.0.1, although the "non-printing webfonts" problem also occurs under Windows XP and Firefox 3.6.17

downloadfonts --> Set to true. did nada Firefox 6.0

OP: I was having the same issue until I saw this page and the comments other users have left. It definitely seems to be related to the proxy issue. I tried two solutions, and they both revealed the problem:

1. Changed the url from http://www.google.com/webfonts to https://www.google.com/webfonts ; this made the fonts show correctly.

2. Tried running my computer on a different, less secure network. This also made them show correctly. So if you haven't already, try getting your computer on the internet on a different connection and see how the page loads. If the fonts work on a different connection, it's a network security issue.

I haven't found a permanent solution yet, I'm not my network administrator, but my guess is (if the above 2 "solutions" work) something would have to be configured in your network security settings to get around this issue.
