Hello, I'm running into an issue with CSS web fonts: They often don't load. This happens in both FF4RC and the latest FF3.6. I'm behind a proxy (an ISA server I believe), and everything is set up correctly (as far as I can tell) in about:config. Today I tried the [https://mozillademos.org/demos/runfield/demo.html Runfield demo]. Everything except the fonts (using google fonts api) loads and the game runs fine. Other browsers load the page (including fonts) without any problems. A quick look in Firebug reveals that the proxy is returning "407 Proxy Authentication Required", but only for the font files. Everything else on the page is loaded correctly. Again, other browsers on the same machine (e.g. Chrome, IE9, Opera 11) load the font files without issue. What's more, if I grab the URL and load it directly, it works fine, downloading the .woff file without issue. This happens with the Google Fonts API, but I'm also seeing the problem on FontFonter.com and FontDeck.com. However, Typekit.com works fine and so do the webfonts on this page. (I've tried restarting Firefox without add-ons and it makes no difference.) Thanks in advance for any pointers.
