This bug is most likely invalid (not a bug in Firefox proper) and should
instead be reported to the authors of the "Favorites Converter (export)"
extension. Do you have the latest version installed?
If no, does the problem dissappear if you update?

improper exception catching/error handling in the extension code is a bug in the
extension.  If a call can fail, you need a fallback.
