Honestly there’s even no need of this as we can manually put such apps in normal ubuntu using gnome-web or chromium. And it works better than this as it opens them in dedicated window and not as new tabs.
Here are some of the issues:
-
Open in tabs. Seriously? Atleast have a dedicated window for each app.
-
What happens when someone uninstalls Firefox? System breaks? Or it works with any default browser?
-
Where’s the need for this? There’s already one out there:

Oh and also, GNOME isn’t the best choice for a web based distro. Something light like lxqt or xfce would be better.
Honestly Rudra, no hard feelings but it would be better if you put your energy to improving what’s already there(unity 8, other ubuntu flavours, etc) and not trying to invent stuff from skimmed versions of Ubuntu with different UIs.
