Would this need ui-r from mconnor? Alex has already advocated this approach and I'd rather not wait half a year for a ui-r again ;)
Neil, please review attachment 276942 [details] [diff] [review] first. The patches are not compatible, and I'm not sure if I'll have time sync them. (Could be trivial, but that's not a given.)

Michael, I haven't looked at your patch deeply, but I think you do need ui-review here. It's not so much about the theoretical solution, but the actual implementation. The old one in bug 347363 wasn't that great.

what's the argument for constant vs. slowly accelerating?  In general, I'm ok with either, I guess I've been using mousewheel to scroll here anyway, so I'm not sure what exactly we're trying to fix here.
Hold down the left or right scroll button on the tab bar. People don't like what currently happens because its too slow, they want a constant scrolling speed.
Will this address the difference in speeds between clicking on the scroll arrow, vs dragging over the scroll arrow (the latter is currently much faster and lacks the "pulsing" nature of the click scroll... maybe smooth scroll wasn't implemented for it the same way?) Also, as noted elsewhere (I can't remember where), if you move the cursor around over the scroll arrow while you're dragging, the tabs scroll even faster! Just noting this stuff in case it helps with getting it all consistent.

I think it was bug 343597.

ui-r=me on the smooth scrolling when holding.

Bug 357081 needs a new sync anyway thanks to bug 339964.

I think it's potentially irritating that scrollByIndex -- which is kicked off in _stopScroll -- can go faster than the constant scrolling. I have yet to actually notice this, but depending on a higher tabMinWidth (or with non-tabstrip scrollboxes) it could become a problem. Other than that, this works pretty well.
