793238 - Allow chrome JS to create DOMError objects

Status: NEW

(Core :: DOM: Core & HTML, defect, P5)

Description

[[:fabrice] Fabrice Desré]

We are removing temporarily the 'builtinclass' from nsIDOMDOMError in bug 790870, but we need to have a proper way to let chrome JS get these objects from the c++ implementation.

If you remove builtinclass, make sure to go through all DOMError usage in C++ and check
if there are any static_casts to the actual implementation, since after removing builtinclass, those
casts may become security bugs.

Thanks for the heads up. I checked current c++ usage and could not find any static cast.

Move all DOM bugs that haven’t been updated in more than 3 years and has no one currently assigned to P5.
