Hello,

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
• On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

Hello,

I tried this on a Windows 7 64-bit laptop and the font seems to render fine (attached image). I did check the console log and I see some errors in loading the @font-face[1]. May be this is causing the issue? Not sure yet.

I also created a simple test HTML that uses the font-face used in this page and it also seems to render fine [2].

Can you please press F12 and then get the details in the Console log for the page and send it over to us. That can help in narrowing down the root cause of the issue.

Also, as already suggested, please try with the safe mode to see if things work fine.

Also make sure that ClearType is enabled.

Vista: Control Panel > Personalization > Window Color and Appearance > Effects: "Use the following method to smooth edges of screen fonts"

Which font is used when you right-click text and open the built-in Inspector (Firefox/Tools > Web Developer;Ctrl+Shift+I) and go to the Fonts tab?

Are the used remote fonts listed if you click the button to show all fonts that are used in the page?

Thanks, but the problem is still present in safe mode. =[

i hope you meant you wanted me to copy everything from the console log; here it is.
