Steps to reproduce:

This issue is specific to Fennec. It works as expected on Desktop Firefox.

1. Install test add-on (attached).
2. Click on pageAction (exclamation mark icon) or browserAction (Menu → Test) (behaviour is the same wrong for both pageAction and browserAction)
3. Pop-up-in-a-tab opens.

Now several wrong scenarios are possible:
* Try to switch to any open tab other than the one which was active before pop-up open.
Expected result:
* The tab of your choice should be active now.
Actual result:
* Pop-up tab loses focus and because of that closes itself.
* After pop-up closed, the tab which was active before pop-up open forcibly activated instead.

Another wrong scenario:
* In an opened pop-up-in-a-tab press "runtime.openOptionsPage()" button (it does exactly what it says)
Expected result:
* Preferences tab should be active now.
Actual result:
* Pop-up tab loses focus and because of that closes itself.
* After pop-up closed, the tab which was active before pop-up open forcibly activated instead.
* Preferences tab is opened somewhere in background.


As for me, the behaviour "when pop-up tab loses focus, it closes" looks OK, but all problems come from the fact that after it closes, previously active tab is forcibly activated. As far as I know, it just doesn't needed: Firefox anyway will activate this tab.
