Didn't work, invalid package
Trying to add https://focus.nirvanahq.com/ for Chrome Version 51.0.2704.103 (64-bit)
Did you upload a custom image?
Didn't even see the options to be able to do that. Doing that worked, but you might want to make the advanced options less hidden.
If no custom image is provided, Applicationize will use the site's favicon. The error you are getting suggests that the site has a weird format for their shortcut icon and Applicationize should be converting it to a Chrome-friendly format.
Actually, they may not have one at all.
This is their shortcut icon: https://d2rjwv8xt02302.cloudfront.net/1459764807/_img/favicon.ico
Chrome probably doesn't support ico files as extension icons.
The fix would be to convert .ico files to .png within Applicationize. Anyone up for this?
I only got that error when I uploaded to the browser without being in the chrome://extensions page. Not sure why it gave that error outside of there, but it worked flawlessly without giving that error from the chrome://extensions page.
