When the user enters sync through several of the entry points, the back button on the Welcome to Sync screen becomes enabled, but does nothing.

Back button leads to bad behavior - can we disable it for about:accounts?

Back button has to work, y'all. It's a fundamental behavior of the web.

Hi Drew,
  Without this patch, loading about:accounts in a new tab enables the back-button, but pressing back does nothing. With this patch it works as expected (ie, the button remains disabled)

I assumed that simple change wouldn't break the tests, but you'd think I'd know by now that that assumption is almost always wrong :/

You're an optimist! :-) (Me too.)

Opened https://bugzilla.mozilla.org/show_bug.cgi?id=1233668 - the patch for this bug does not add the first FxA page to history and causes a problem in Firefox Accounts - window.history.back() cannot be used to go back to the initial page!
