I often use multiple tabs (30 or more). Since I upgraded to Firefox 17, the addon that I had been using to allow tab stacking is no longer compatible. (I believe Tab Mix Plus was the add-on).
I'm not interested in changing the color of my tabs or having them listed down the left side of my window. I'd like to have them all along the top of the window in rows.
Does anyone know an add-on compatible with Firefox 17?
