69016 - Mozilla should Output HTML-Parser-Errors

Status: VERIFIED DUPLICATE of bug 6211

(SeaMonkey :: General, enhancement)

Description

[Raphael Bosshard]

XML has to be valid and well-formed, as set in the XML-Specifications Otherwise
it should not be displayed. 

Following HTML-Specifications, that is no "must" to user-agents.

Nevertheless it would be nice, if Mozilla would hint to html-parse errors, in
example, in the form of an icon. When clicked, all html errors would be displayd.

Use of this: more valid html-pages out there ("why chance anything? the browser
doesn't complain..."

This enhancement request has been around for a long long time.  And hopefully
it'll even get implemented....
