First contribution from an outsider on this one! https://github.com/Aronnn
There is a small problem with users opening tabs via middle click or the context menu on some link. I am aware of this problem but current there is no good way to solve this problem.
Bug 1) The first time firefox loads, it places the focus correctly (this is only a factor if
Bug 2) The pref extensions.cnt.focus it placed in install() and startup() under the correct reasons.
Bug 3) The preferences dialog is not large enough on macs. There is now a min width and min height
This bug is actually in Firefox but CNT implements a work-around.
Also, I increased the max version to 16.0a1
