== The first browser blinks on XHTML parsing

I'm late to the party, but [[Opera has decided to stop strict parsing
of XHTML

(via [[Sam Ruby

I have [[long said XHTMLChicken]] that draconian XHTML error handling
is an unstable equilibrium and it would only last as long as all of the
browser vendors didn't blink. Well, Opera has blinked; they've picked
the user friendly alternative over the strictly standards compliant one
(or semi-strict, since they apparently already offered an option to
reinterpret the page as HTML, unlike eg Firefox). It now remains to be
seen how long it will be before other browser vendors do the same thing.

(I expect Firefox to be the last holdout because Firefox people are
in some ways very user hostile in the name of doing 'the right thing'.)

While this Opera blog entry was about a development
snapshot, [[the announcement for Opera 11.60
http://my.opera.com/ODIN/blog/2011/12/06/hello-opera-11-60]] mentions
this as a feature of 11.60. So this is now out there in the wild in a
general release browser.

(Now I'm wondering if someone has or could make Firefox extension to
do the same thing.)
