This is how i think Mozilla can capture more users back to Firefox. By providing "extra" services attached to the Mozilla and Firefox brand will make them a superior product to the end user.
Sure it's hard to compete with Chrome but if you offer useful features and services integrated in your Browser i see that Mozilla actually has a chance to compete with Google for the browser space.
This is one of the "advantages", if you are a heavy Google user, of Chrome over the competition is that everything is attached to your Google account. Passwords, history, spellers, dictionaries, shortcuts, etc...
If Mozilla comes with Send, Notes, Password Manager all integrated in Firefox i see a good way to bring back some of the previous users that switched to Chrome.
Currently, I need to set up my own email hosting through a service like fastmail and then configure a desktop client(like Thuderbird) to use it.
A Mozilla Gmail-esque service would remove a lot of the friction there and probably bring in a bunch of users who are tired of google running everything.
We don't need another AOL Chrome.
How is that different from the complaints people make about Chrome tightly integrating with Google?
As a Chrome user I can confirm. But for me the main raison I use Chrome is for the dev tools a found them better than FF
