But in this way you disable the HA. I guess mozzilla should release an update for fix thsi problem

@ a587626

all that does is turn off hardware acceleration that we already have done in the settings.

I have selected ClearType to be disabled in my OS, and it works in Windows Explorer and all other applications etc. (all except Adobe Reader and Windows Internet Explorer, which is primarily why I use Firefox...)

Since Windows handles non-ClearType fonts with hardware acceleration, and Firefox <17 managed to handle it as well, I see no reason why disabling hardware accelerated graphics in Firefox 17 should be regarded a valid solution to the problem.

I have downgraded to Firefox 16.0.2 and will wait there until this is fixed.

Sweet!

Thanks member "a587626". Setting gfx.direct2d.disabled to true, then restarting Firefox 17 worked for me too.

Disabling hardware acceleration (setting gfx.direct2d.disabled to true) is only a partial solution, makes fonts looking thinner but it isn't the same look and quality of anty-aliasing as it was in previous (16.0.x) versions of FF. I want to get back fine looking fonts with hardware acceleration enabled.

That also disables HW acceleration, and as thus is not a true solution but a temporary workaround. Still, thanks.

Hi guys,

We are looking into this issue right now, but we need more information. Anyone will to work 1 on 1 with us to get this solved, please PM me. Also, if you could list your graphics cards and drivers in this thread that would help as well!

Windows 7/64, Nvidia driver ver. 296.10 (WHQL), GeForce GTS450.

Windows 7/64-bit, GeForce 8400GS (ASUS EN8400GS Silent), NVidia video driver 306.97 WHQL.

PM sent.

Nvidia GTX 560Ti, driver: 306.97 WHQL, Windows 7 SP1 64bit

Windows 7/64bit SP1, AMD Radeon 6950, AMD Catalyst 12.10 2D-driver version 8.01.01.1266, Windows ClearType disabled

Windows 7/32bit SP1, Nvidia 9600 GT, Driver: 9.18.13.0697 - nVIDIA Detonator 6.97

Thank you for submitting this ticket. I am using Firefox and Seamonkey, both got ugly after update. I downgraded FF to ver.16 and changed the hardware acceleration option in Seamonkey. I will see what is the best option.

I am disappointed in Firefox programmers, again...

Same problem for me. Disabling the hardware acceleration removes the much unwanted blur, but some fonts are still hinky, especially on this site.

Windows 7 X64 - NVidia GTX 670 driver version 301.42

Setting gfx.direct2d.disabled to true only partially helps. It's better but still bad, I'm going to have to revert versions.

It lost the boldness, but it's still "imprecise" for lack of better word. Almost as if there's a resolution mismatch type issue?

(Edit: I'm not sure if this was correct anymore, since I didn't restart after it. It may have fixed it entirely then, but I'm not sure.)

Again blurriness is back

Hi guys! Thanks for all the feedback. We've got a bug on file for this and several volunteers to help us get to the bottom of it. Hopefully we'll have some answers and a resolution very soon. Please be patient though as the Thanksgiving holiday in the US is this week.

Isn't this the same as disabling hw acceleration in the settings, but "another side"
