[Bug 1027501] [NEW] firefox dropdown menus break after url launched from dash

[Gary Bishop]

Public bug reported:

To reproduce:

1. Use the Dash to locate a URL. I used the bookmarks-lens but there are probably other ways.
2. Select the URL and Firefox will open it in a tab.
3. Close that tab.
4. Notice that dropdown menus such as the search engine selector or even the completion dropdowns on the awesome bar or the search box stop working. 

This happens when running in safe mode as well.

As I said above it happens with the bookmarks-lens and with my simple
python favorites-lens https://github.com/gbishop/favorites-lens but I
don't think the problem is in the lens. Either lens is simply providing
Unity with a URL.

I assume Unity is supplying the URL to Firefox with something akin to
xdg-open. But xdg-open does not cause this problem.

I don't see any messages in the terminal nor in the error console when
this is happening.
