Cannot know if the radio button is focused
As the sample html in Troubleshooting Information, there are two radio buttons on the page. In IE9, if you focus on one of them, there are gridlines around the focused radio button. But in Firefox 7/8/9, it does not show the gridlines, and you cannot know if you are focusing on the radio button. To see if you are really focus on the radio button, try the Up/Down key on your keyboard, if will turn to the another radio button on the sample page.

Sample html:
<div> <input id="radio0" name="rl" value="radio button 0" type="radio"><label for="radio0">radio button 0</label> </div> <div> <input id="radio1" name="rl" value="radio button 1" type="radio"><label for="radio1">radio button 1</label> </div>

Works here on Linux.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

Thansk for your quick response.
I could repro this issue on Win7 FF 7/8/9 in Safe Mode with default theme. I used to re-install Win7, and install FF with default settings and did not install any add-ons.
I am trying to find out if it is a known issue. [http://kb.mozillazine.org/Accessibility_features_of_Firefox]
The default value of browser.display.focus_ring_on_anything is FALSE. After turn it to TRUE, I could see the focus, but FF also show focus on any other elements.
