+++ This bug was initially created as a clone of Bug #742944 +++ Gaia issue: https://github.com/mozilla-b2g/gaia/issues/1802 For HTML structure like this: <iframe mozbrower> <iframe> <button onclick="alert('hi')">Alert</button> </iframe> </iframe> The alert() call can bypass the mozbrowser capability implemented in Bug #742944 STR: Launch Gaia "UI Tests" app and try the alert/prompt test.
Is the problem alert() or window.open? Or do both not work within <iframe>s?
Also, these dependencies / blocking bugs are probably not what you mean, but I'm not sure what you mean for this bug to cover, so I don't want to change them.
@jlebar Yeah I totally missed up with the dependency thing ... I've updated the title. Can you fix the dependency? Thanks.

Created attachment 635171 [details] [diff] [review] Tests, v1 This was a pretty dumb bug. Oh well.
Created attachment 636066 [details] [diff] [review] Patch v2 Even better; now it's a one-line fix.
What is the change to nsGenericElement.cpp ? https://hg.mozilla.org/mozilla-central/rev/f3cd319dd52d
