This breaks Weave so that it does not work. (Or at least, there's no statusbar icon for Weave) Reproducible: Always Steps to Reproduce: 1. Update to the 4-25 Minefield build. 2. Start Firefox with Weave installed. 3. Encounter the error.

Comments from bug 561646 say the change was intentional.

Just noticed bug 561638. Marking this as a duplicate.
