With my FF extension I would like to track and store errors using
window.addEventListener('error', listener, false)
This works fine for sidebar scripts and browser action scripts but not for content scripts injected in a page - even if the error occured in the content script itself, which doesn’t seem to violate the “different origin” restriction on ErrorEvents:
When a syntax error occurs in a script, loaded from a different origin, the details of the syntax error are not reported to prevent leaking information (see here)
And it doesn’t seem to work for the background script either.
Is there a way to access those errors (in injected content scripts and in the background script)?
The reason behind it is that I want to enable users to mail more sophisticated bug reports than “it doesn’t work. why???”
