Steps to reproduce:

I was browsing websites, Facebook, reading news, forums, etc. and I discovered Firefox 19 is having a very serious problem displaying websites, because it shows blurred letters.





Actual results:

Firefox 19 is showing blurred letters when browsing websites, during certain conditions. To understand what I mean, just take a look to these screenshots...

This happened to me at Google, Youtube and even in the Mozilla Firefox forums.

Seems to be when the text is close to GIF animations, it is shown blurred.

Also, if I press the right click of my mouse and I get the contextual menu, in the contextual menu, I've seen sometimes also blurred letters.

I confirm you this is not a failure of my windows, because this never happen in any other software and other browsers works fine, as Chrome, Maxthon or Explorer.

The failure is very disturbing and do not allow users to enjoy the web browsing experience. I am using Chrome right now until you fix this.


Expected results:

Showing characters normally and not blurred.

Could this be related to this?

Seems to be the problem can be fixed deactivating the Hardware acceleration... going to: Menu... Tools... Options... Advanced... and deactivating the hardware acceleration when available.
However this problem is still there, because hardware acceleration cause websites to fail and show blurred letters

Do you have ATI GPU, just like in the bug above?
Does the bug happen when running in Safe Mode? https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
If so, I think this should be moved in "Graphics: Text" component.
