Quick traversing (scrolling) of currently open tabs (Ideally visually)

[Willmish]

Sometimes you don't remember the name of the tab but rather its "rough" position in the current window. Default scrolling through tabs in firefox is painfully slow, so adding a feature to e.g. jump to XX% of the window or quicker scroll would be nice.

• Jumping X tabs to the left/right
• Going to XX% of the current window
• Vim-like jumps to recently visited tabs (Ctrl+O, Ctrl+I in vim)
