I see this question has been asked in different ways but perhaps not in such a direct manner. I'm on a fresh load of Windows 8.1 with a default setting of ClearType Disabled. Web Fonts render perfectly fine in all browsers except for Firefox. In Firefox, they appear blurred or pixelated. When I enable ClearType they suddenly are fine in Firefox. Oddly if I then disable ClearType and logout and then login, they are still fine. I see that Google Chrome previously had a similar issue but understand they fixed the issue in Chrome. Is this an issue that needs to be addressed by Firefox? Are antialias properties going to be advanced in CSS to possibly force fonts to render properly? (Fonts are stored locally on the same domain as the website.)

Hi, 

I understand that you are asking about why when ClearType is disabled Firefox has blurry font.

If you take a look at the about:config entries on the page and search for cleartype, you will see that gfx font rendering is set to false. However for downloadable fonts it is true. It may be that you were on a site that had a downloadable font, or hosted on the web server host. There is also a force use for certain type in gdi classing family and max size. These can be changed by the user, however those are the default values currently.

You can leave feedback for the developers about this in input.mozilla.org as well.

So if all of other browsers do not exhibit this issue - would that not mean that Firefox should be improved? As stated, I opened the site in multiple browsers other than Firefox without issue. The issue only exists in Firefox. I see that Google Chrome previously had a similar issue but understand they fixed the issue in Chrome. Is this an issue that needs to be addressed by Firefox?
