A new version of Firefox/Chrome is deployed to (nearly) all Firefox/Chrome users within a week or two. AFAIK, There is no auto-upgrade from IE9 to IE10 (only one I know of is IE10 to IE11).
I believe that as a result of above, compat hit is a bigger concern for Firefox/Chrome than it is for IE. Websites don't see the sudden switch to breakage with IE that Firefox/Chrome changes can bring. I have no concrete model or reasoning to back this up and would be happy to be proved wrong. -dev On 20 August 2013 19:48, Tanvi Vyas <ta...@mozilla.com> wrote: > On 8/19/13 11:51 AM, Devdatta Akhawe wrote: > >> I also think the comparison to IE is not apt---in the absence of >> auto-upgrade, the compat hit IE takes is much lower.
