SecurityError: The operation is insecure. frame.inner.js in firefox?

Am I the only one getting that? Using the bookmarklet. The page is blurred, but that's it. I use uBlock but have unblocked the blocked request (except the one twitter one, which I don't see why should be required)

Firefox 44.0

(Seems to happen both on https and http site)

Probably related to https://bugzilla.mozilla.org/show_bug.cgi?id=866522 (ie. not it's a firefox issue)

Same error, firefox 54.0b12 (64-bit)
