Please report any other irregularities here.
This is a spin-off from bug 476464: since many extensions / xul applications forget type="content" on frames that will load web data it would certainly help to show a warning in Error Console if a non-chrome document is loaded into a chrome frame. Not quite sure how a non-chrome document would be defined - the case is clear for http: and https: but already less clear for resource: and file: which also have restricted privileges.
Can we close this now, with WebExtensions?
It's still a footgun for our own development, but I don't see anyone changing this at this point so sure. We're more likely to just fix bug 476464 (or not) but not add this warning.
