So the flexbox model has changed, and it breaks md-content scrolling with the latest browsers.

Some background :

Chromium's bug report : https://code.google.com/p/chromium/issues/detail?id=506893
Firefox's bug report : https://bugzilla.mozilla.org/show_bug.cgi?id=1043520
Angular-material's bug report: angular/material#3901

It should be fixed by angular-material in the next release, but meanwhile the quick fix is this following CSS code:

[flex] {
    min-height: 0;
    min-width: 0;
}
