An easy and effective solution to the problem of users having the HTML5 parser disabled because they've flipped the pref prior to Firefox 4 final for whatever reason but particularly due to the Hotmail reload issue would be renaming the pref in Firefox 4. This way, the pref would reset to HTML5 parser enabled for everyone. Also, as long as we aren't taking the pref away, it should show in about:support, since the pref has a notable impact on how the product behaves.

What about extension compatibility?
(In reply to comment #3) > What about extension compatibility? Extensions should have no business flipping this pref. Do we know of extensions that flip this pref? If so, why do they flip it? The only even remotely legitimate reason for an extension to flip this pref would be aiding in debugging, but it seems kinda silly to have an extension to that for debugging when the people who need to flip this for debugging could do so manually in about:config.
They may not actually flip it, they may just be checking it's value. There's no knowing what extensions will do. Changing a pref this late in the cycle *may* cause some extension issues, not sure if and how much, just thought I'd make note of it.
Missed some tests.
Personally, I think we should make this change, if people have actually been suggesting this pref be flipped on anything other than a temporary testing basis. :(
We can evaluate an approval, but there is no way this blocks release.

Comment on attachment 515082 [details] [diff] [review] Rename the pref, make it show in about:support, v2 I personally think we should take this, if beta testers still have this pref changed I think we should force them to re-think that decision so that they can let us know if the reasons they flipped the pref in the first place gets brought to our attention (again, if so needed).
Depends on: 636690

I think that the aboutSupport.js needs to be checked in separately if this patch doesn't get approval. The risk is negligible and it will be very useful in diagnosing user support issues, especially if more and more people are following the advice of "just set html5.enable to false to fix it".
WRT about:support, see bug 593443 (which already mentions this one). A much simpler patch would be to just reset the existing pref on update, rather than renaming it. It'd have a much lower impact and would avoid the potential issue of extensions checking this pref for whatever reason as brought up by Natch above. Is there an easy way to just reset it on upgrade to Firefox 4?
