i find collections super handy and use them but the fact they are not exposed (even in rudimemtary form) in desktop UI is appalling. the usefulness of collections drops by some 50% to me - i basically need to reopen a saved page in mobile, send it to the desktop browser (using "send to device" feature) and then, probably, save it again in bookmarks.
The existing gap between even the core features has been puzzling for a while.
On mobile I can add a current page to home screen, collections and the top sites. Neither is available on desktop (with the same profile).
WTF mozilla? What kind of usability is this? I am totally not looking forward switching to another browser but it looks inevitable...
