This loads a JS file to register the Custom Element whenever XUL documents get created. This is a pattern we plan to follow for future elements as well - stringbundle is just an easy target to prove it out with. MozReview-Commit-ID: 7PlisCknrKW --HG-- rename : toolkit/content/widgets/stringbundle.xml => toolkit/content/widgets/stringbundle.js extra : rebase_source : 5bf94038556c9b956de3678cd4bc817f5d837f45
