A number of Firefox users have complained of the text looking blurry on some pages since the upgrading to Firefox 4. The problem still exists for me with Firefox 5. I notice it particularly on 'w' and 'v' at certain levels of zoom or text size. It probably also depends on the computer's ClearType settings, so may not be noticed at all
However, if anyone has noticed this and would like to cure it, there are a couple of ways it can be done:
1. Go to: 'Options > Advanced' and remove the tick from 'Use hardware acceleration when available'
2. Install the '
Anti-Aliasing Tuner' extension. This has several options for changing the way text is displayed.
The second method is perhaps better because it leaves the hardware acceleration feature enabled. This makes better use of the computer's graphics card, which makes the browser faster when it comes to animations.
