Chosen solution

There are many extensions that no longer work in the latest Minefield nightly builds because of changes made to registering XPCOM components. See http://forums.mozillazine.org/viewtopic.php?f=23&t=1937759

That is a problem with the Skype extension. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
