FishEyeTabs is a tiny extension for Mozilla Firefox that makes tab selection easier when many tabs are open. If tabs become too small, their labels are not readable. In Firefox 1.5 scrolling was introduced, which is often distracting, because the user has to switch from clicking tabs to clicking arrows and back. FishEyeTabs is an alternative to scrolling, it makes tabs visible using fisheye-style zooming. It is enough to move the mouse cursor over a tab, and it becomes visible automatically.

Zooming becomes active when there are enough tabs open to occupy the whole width of the screen. The close button from the tabs has been moved to the right to make it easier to be clicked. Tabs are restored to standard size when a tab is opened or closed, or if the mouse cursor is moved down to the status line.
