In addition to theme and UI changes already discussed for Firefox 3.7 and 4.0, there are some proposed Linux specific visual changes:
- Consistent Back/Forward Buttons: Use the same back/forward shape as on the other platforms. The back button would use the same texture as the other buttons however it would be round and larger.
- Buttons vs Icons: Switching to a button+glyph style for the toolbar items. This would be instead of the more representational style that is widely used. It also is a deviation from the common system standard of having icons and then a button shape on hover.
