I can confirm the login behaviour works similarly in Firefox.
As for embedded images, I'm not sure what pk46 means by 'blank'. if "Block all images" in Settings is enabled, I see a place holder instead of the actual image like this:
A click on "Show Image" will reveal it. Interestingly the size of the place holder reflects the size of the image. A large
image will give a large place holder and, if it's quite big, it becomes noticeably blurry. I think I would prefer something more subtle here such as a standard sized icon simply indicating there's a missing image which would make it easier to skip past the place holders to concentrate on the text. But this is a debatable design decision which doesn't bother me too much.
What is bizarre and irritating is (when the Preview Pane is enabled) having to triple-click an e-mail to open it in its own window! I wonder if this is a bug or a deliberate design feature for some obscure reason. Surely a double-click should be sufficient. I've checked the behaviour of the previous interface using an address that hasn't yet been upgraded and can confirm a double-click works there as I would expect and am used to. It would be good to know if the development team are aware of this.
