User Agent: Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0 Build ID: 20120312181643 Steps to reproduce: I created a littele Javascript that checks if DirectWrite subpixel positioning is active in your browser. It works by comparing the width of a div at a small font size to the width of a div at large font sizes. I ran the test on multiple websites with thousands of visitors. Check the script here: http://jossele.de/font-direct-write-detect.html Actual results: I realised that DirectWrite (with subpixel positioning) in Firefox is only activated on 4% of the Windows 7 machines. Expected results: It should be activated on much more machines to have consitent rendering and more people benefit from better text rendering.
For information what i mean with subpixel positioning, see this post: http://blog.mozilla.org/nattokirai/2011/08/11/directwrite-text-rendering-in-firefox-6/

I have a Windows 7 machine with DirectWrite enabled and yet your script displays DirectWrite subpixel positioning: false I think you need to choose a different font to Verdana as by default that is in the default gfx.font_rendering.cleartype_params.force_gdi_classic_for_families list.
Ok. Thanks! I just realised this. I will check it and write again in a few minutes. Sorry!

Returns true now you've changed it so you need to start your survey again.

Ok. Now with different fonts I detect that DirectWrite is on on approximately 50% of the machines. Much better but than my previous results but still not perfect. Is this because of blacklisting of old drivers? IE9 has 99% here! Now I could close the bug or ask you guys to consider enabling it on more machines... But I guess you already considered that.
Summary: DirectWrite off on 96% of windows 7 machines → DirectWrite off on 50% of windows 7 machines
