Nvidia Geforce GTX 670, Win 8 x64 Pro, driver version 310.61 beta

To (possibly) resolve this without disabling hardware acceleration/Direct2D, try changing the setting "gfx.content.azure.enabled" to false in about:config and then restarting the browser.

I've the same problem.

AMD ATI Mobility Radeon HD 4300 Driver 8.821-110126a-112965C-ATI

Thanks. gfx.content.azure.enabled = False worked for me (in place of disabling hardware acceleration).

@jfkthame, @ecarlson It isn't final remedy but only next temporary solution. This only disables 2D API named Azuro, where probably problem is hidden. It is only step on the way to identify and fix core of the problem.

Hey guys! Thanks to everyone who helped us in troubleshooting this. We are fairly certain it's an azure problem. There is a patch in the works and setting gfx.content.azure.enabled = False seems to work in the meantime. I don't know if the patch will be part of a chemspill or wait until 18. Thanks for your help and patience.

Happy Thanksgiving!

It's serious? Wait Firefox 18? I'm not sure whether I should laugh or cry...

Same problem here, I have cleartype disabled in Win7.

I agree, but at least they're fixing it. :/

You guys realize you don't have to live with the text till then right? It was posted how to get it back to normal in the meantime:

1. Go to about:config
2. Find and set gfx.content.azure.enabled to false
3. Restart the browser

While I think many people underestimate how awful ClearType is for us who prefer pixel-perfect text, and it would be a smart move to push an update for publicity reasons, it sounds like some of you are worrying about having to deal with it for a long time. That just isn't the case.

I could never understand what's the point of ClearType. Font just looks awful with it. The blurriness and the reddish outline in some places, why would anyone want that? There must be something behind it, but I just don't see it.

You can set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.

I have a font issue after upgrading to Firefox 17 on MacPro.

I don't have gfx.content.azure.enabled, gfx.direct2d.disabled in about:config.

See my screenshot.

A space appears where there isn't one. Example

Observed: "text1 text2"

Expected: "text1text2"

For Windows users, the blurry fonts issue will be fixed in Firefox 17.0.1, which should be released very soon (hopefully, tomorrow). More info here:

Once for all, the final solution to the ClearShit

Simple add the following two lines in Pref.fs

/* Disable the putain de Cleartype in the webpages */ user_pref("gfx.downloadable_fonts.enabled", false);

Updated to 17.0.1 didn't help....same shitty blurry fonts

Hm, it works for me. gfx.content.azure.enabled set to true and I don't have blurry fonts.

Firefox 17.0.1, cleartype off, gfx.content.azure.enabled set to true (default) and I always have blurry fonts.

And cleartype is definitely enabled on my firefox. Why firefox transgressing the user preferences? For IE9, it is understandable, but for firefox ... new policy?

They released 17.0.1 to fix the blurry fonts without have to go to the config and change the azure.

So the patch didn't worked....

Violon, forhike: could you post a screenshot of what you're seeing in FF 17.0.1 (with ClearType OFF), please? Does this affect ALL fonts, or only certain ones?
