Firefox:1.5 Accessibility

(My first ever Wiki edit, please excuse poor quality)

• Accessibility of XUL widgets should be reviewed? (Ben Goodger mentioning focus selections on the widgets in the preferences window)
• Keyboard customization (as mentioned elsewhere)
• Text-rendering mode like Opera would be good? Also a useful tool for developers for testing semantic markup. This would help boost people's enthusiasm for suppling accessible sites by making testing far faster (Lynx isn't always that easy to setup and configure)
• New buttons on toolbar customization sheet for increase / decrease font size and/or other accessibility options?
