An alternative to scrolling when there are many open tabs, and they become too small to be seen. User can zoom tab labels by moving the mouse cursor over them. Fisheye zoom is activated only when tabs occupy the whole width of the window. Close button moved to right FF 1.0 - style (tabs can still be closed easily by clicking them with mouse-wheel or left+right simultaneous mouse-click). If user still wants to have a close button on each tab (although not very usable with FishEyeTabs) this can be achieved using TAB X add-on or manually changing browser.tabs.closeButtons preference.
