Since this is only running in the context of the background page you could use
`Services.vc.compare()` here. That of course requires a mock implementation for
the test environment (e.g. using `parseFloat()`).

Done.

+                Services.vc.compare(info.platformVersion, "6.1") == 0 ||  // extensions are broken in 6.1 and 7.0

             UI.openFiltersDialog();
           else
             global.openOptions();

window.openOptions() is deprecated. Please use ext.openOptions(). And while
implementing some parts of the abstraction layer for Firefox, you might want to
implement ext.openOptions() as well, and get rid of the switch above.

I filed #1813 and #1814 on that.
