Not a regression; AFAIK we never implemented fallback.
(In reply to comment #3) > Not a regression; AFAIK we never implemented fallback. You're right about fallback, but before canvas was implemented, it behaved as expected. :-)
minusing. too late for the 1.5 train and no patch in hand. I'm also basing this on Vlad's comment.
Created attachment 582269 [details] [diff] [review] Show canvas fallback content when script is disabled.
This behaviour might be worth to be documented
Documentation updated: https://developer.mozilla.org/en/HTML/Element/canvas And mentioned on Firefox 12 for developers.
