The first version is tab-bar.js, which is the older variant using a classical tab look.
- Classical look on the tabs, with "close" buttons on the right hand side of the currently selected tab.
- Favicon support.
2. Known problems
- Can cause flickering and 100% CPU time when having a certain number of tabs open. We think we know what causes this.
- Difficult or impossible to skin properly at the moment. There has been some discussion on the causes of this, but it really bottoms down to the "!important" CSS property.
