1) Open a new tab (i.e. about:newtab)
2) Click one of the thumbnails


1) Open a new tab (i.e. about:newtab)
2) Enter "" and hit Enter

The issue here is that before (2) we show "New Tab" as the tab label. As soon as you click the thumbnail or hit Enter in the Awesomebar we switch the tab label to "about:newtab", until we get the target page's tab title.

This adds flickering for a very common action, and is an implementation detail we shouldn't expose.
That's actually a Session Restore issue, caused by, I think, switching the tab to be remote.

While investigating bug 1423256, I've found that this patch has caused the "New Tab" label to no longer be displayed on the Activity Stream page, while it is displayed on the old about:newtab.

The initial issue which you were seeing was caused by Bug 1413550.

A similar behavior can be observed for the about:home page. Instead of the "New Tab" label, "about:home" is displayed instead.
Tim, do you want me to log a separate bug for this?

I commented in bug 1423256. We can probably revert this patch here if people fix the activity stream page.
