1147139 - Fetching tabzilla over http redirects to https on mozlla.org

Status: RESOLVED FIXED

If I fetch the tabzilla css via https it works as expected:

$ wget -O /dev/null https://mozorg.cdn.mozilla.net/media/css/tabzilla-min.css
--2015-03-24 21:19:06--  https://mozorg.cdn.mozilla.net/media/css/tabzilla-min.css
Resolving mozorg.cdn.mozilla.net (mozorg.cdn.mozilla.net)... 68.232.34.191

HTTP request sent, awaiting response... 200 OK

But if I fetch it via http, I get redirected to mozilla.org via https which is bad since the load of css will block first paint on sites using tabzilla:

$ wget -O /dev/null http://mozorg.cdn.mozilla.net/media/css/tabzilla-min.css

There is a similar problem for http://mozorg.cdn.mozilla.net/tabzilla/tabzilla.js . This is supposed to do a single redirect to add the locale, which it does when loaded over https, but it does two when loaded over http.

This issue could be fixed in some way but mozilla.org and CDN are only serving content via https since last July (Bug 796109) so I think the Tabzilla document [1] just needs to be updated to recommend using https, not protocol relative URLs.
