2. Minimize the window until the tab scroll bar appears
3. Move the mouse cursor over the app tabs and scroll the tabs with the mouse wheel

Actual results:
The mouse scroll doesn't work

I have had this problem bug me for quite a while. It still occurs when I disable all addons and plugins. Basically I have lots of tabs open (which is very often for me) and the left and right arrow buttons that are used to scroll through the tabs do not work, or work very intermittently. Also using the scroller on the mouse doesn't work. 

I actually had a new bit of information just now. I had the Error Console open while working on something else and noticed 2 errors that came up whenever I tried to click one of the left/right tab scroll buttons. Here is the error:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMWindow.mozRequestAnimationFrame]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: chrome://global/content/bindings/scrollbox.xml :: arrowSmoothScroll_start :: line 648"  data: no]

Error: uncaught exception: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDOMWindow.mozRequestAnimationFrame]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: chrome://global/content/bindings/scrollbox.xml :: scrollAnim_start :: line 283"  data: no]

I can use the Ctrl-Tab key combo to go to the next tab but still the tab strip doesn't move so that I'm sometimes on a tab that isn't actually showing at the top. It's very annoying.

Whenever I use the key combo, I still get an error - it's just the second error I copied above. So it seems like when I use the key combo, there is a failure in scrollAnim_start, and when I use the arrow button there is a failure in both that and arrowSmoothScroll_start.

How to repeat - open lots of tabs so that they don't all fit at the top, then try to scroll left and right through the tab strip.  I often use the middle click of the mouse to open a link in a new tab but I doubt that has anything to do with it.

Firefox version 12.0 but I believe this has occurred through several updates.

I am still facing the same issue on 14.0.1 under Windows 7 x64.
The most annoying thing is that if you switch to a tab displaying a Flash animation or a PDF using Ctrl-Tab you get stuck here as neither Ctrl-W nor Ctrl-Tab will work (I think keyboard actions are hooked by the corresponding plugin).
In such case, you need to click on one of the tab you can see in the tab strip to be able to switch again.

I still have this problem in 15.0.1. The line in scrollbox.xml is now 652 or 287.
