+  direct link images. Fixes [#2041](https://github.com/mozilla-services/pageshot/issues/2041) [8dfd52e](https://github.com/mozilla-services/pageshot/commit/8dfd52e)

+* even if user.initialize() is called many times, do
+  not keep sending requests to the server. Fixes [#1956](https://github.com/mozilla-services/pageshot/issues/1956) [85db7e7](https://github.com/mozilla-services/pageshot/commit/85db7e7)
+* do not show error popup on startup if we can't
+  login to the server. Fixes [#2006](https://github.com/mozilla-services/pageshot/issues/2006) [738eedf](https://github.com/mozilla-services/pageshot/commit/738eedf)
