That error appears to come from an add-on. To test this try the procedure in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article.

When you check your list of add-ons, look for an add-on that has "saff" in its name or the initials s.a.f.f. , that will likely be the one causing the problem.
