EDIT: I'm using firefox 4.0 beta to achieve this. It doesn't let me move tab bar, but it lets me move other stuff onto the tab bar, which is basically the same.
Hi, I'm using Firefox on my netbook, and I want to save as many vertical pixels as possible without turning to full-screen mode. Right now, the only thing in my way is the fact that the tab bar can't be moved like the navigation bar or the bookmarks toolbar. I'm looking for a Firefox add-on that will let me place the tab bar side-by-side with the other bars.
CLARIFICATION: I do not want to make the tab bar vertical. I want it to keep it horizontal. An example: if you right-click an empty space in the navigation toolbar and then click "Customize", you can drag the bookmarks toolbar and place it side-by-side with the navigation toolbar. That's want to do with the tab bar. I'd like to place it right beside the navigation bar.
Is there an add-on for that? (the lighter the better)
