While I didn't think that supporting a mode like browser.tabs.animate = false was necessary, since we have that value available, we implicitly claim support for it, so I will fix this.

On Nightly 8.0a1 (2011-08-16) opening tabs when there are enough to scroll left/right also ignores this preference - whether you click the + button or press Ctrl+T. Same bug or file a separate one?

Same one apparently :)

In addition to opening new tabs, scrolling through them (using either the arrows at the edges or the ctrl-pgup/pgdown keys) is also broken. (7.0 release)

I think the preference you all are looking for is the rather strangely named: toolkit.scrollbox.smoothScroll

Thanks, but it's not the one. Setting it to false does disable a different piece of tab animation, and I'll be experimenting with that as it makes the browser seem faster/more responsive, but it doesn't deal with the animated tab resize.

You may have to restart the browser to see the effect.

I did that before posting Comment #9. As I said, the piece of tab animation it disables is not the one described in the original posting.

This config option does nothing to disable the new drag animation implemented with Firefox 17.

I also cannot find any option to disable the center effect when dragging tabs on the new version, but that's for another report.  Still, if anyone sees this comment and knows of a way to disable this centering effect, I would greatly appreciate the details, as this change has SEVERELY reduced my efficiency at managing multiple tabs, of which I do on a daily basis (100+ tabs).
