Re: Text in 4b5 is somewhat blurry on most sites; text was clear in 4b4 and earlier. How can I fix this?
This is caused by hardware acceleration. You can resort to the previous font rendering by turning off hardware acceleration. To do that open the options dialog (Click on the Firefox button, then select Options...), go to the Advanced panel then select the General tab, then de-select the setting to use hardware acceleration.
