Forgot to mention that when you change tabs location (from top to bottom or bottom to top), your primary tab must be the Add-on manager. (just in case it wasn't clear enough). 

One more thing, you can solve the button issue by going to another program. (for example, you go to Mircosoft word and type something. You come back to firefox, with the back and forward button issue fixed.) 

Thanks.

Not sure there is any specific notification that the tab state has changed for us to use here.

Dao, is there an event when this setting gets changed?

There isn't. We could add one, I suppose...
