231513 - Quirks mode compatibility with IE

Status: RESOLVED DUPLICATE of bug 45333

(Core :: Layout, enhancement)

Description

[Michael Baffoni]

IE is a defacto standard, not to be confused with the standars put out by the
W3C.  Since Mozilla is now an end-user product and not just a development
project, it should be focusing on more than just strict adherance to published
standards, it should also attempt to properly display content that adheres to
many "quirks" of IE, the most often used browser on the Internet.

I'm not suggesting that Mozilla should have a bug-for-bug compatibility with IE,
however it would be usefuly to support commonly used DOM code properly processed
by IE.  For example, the technically incorrect code at the core of bug #231013,
which is not only recognized by IE, but Safari has specifically gone out of it's
way to support (one of the hallmarks of a defacto standard is that others
replicate the "bug" support).

If people still feel the need to have the browser break on the page rather than
processing it as it was intended, feel free to make this an option (a checkbox
for "IE compatibility" or "enforce stict HTML compliance", etc.).

Wrong component, and duplicate.
