I wonder whether this is specific to visiting the page via "manage account", or whether just accessing https://accounts.firefox.com/settings on the web would show a similar effect.

It seems to reproduce when visiting https://accounts.firefox.com/settings.

I was also able to reproduce this with Firefox 36, so it's not a recent regression.

It's probably a problem with remote code then, rather than anything in the browser; changing components to reflect that.
