Find tab — Jakub Duchniewicz

With too many tabs open, finding the one you currently seek is as easy as hitting 'Ctrl+Space' (or other shortcut you specify in the settings), and typing part of the tab's title. Addon automatically adjusts its color scheme to match the currently loaded Firefox theme (note: not all themes provide necessary CSS fields, in such cases a default value is used).
You can switch between searching both in current window and in all open windows, by pressing 'Ctrl+Shift+Space'. You can also close currently selected tab by hitting 'Ctrl+E'. If no tab matches the search query, a new tab is opened with a google search.
