Extension can be made via http://crossrider.com/
We need to develop browser extension. Extension is supposted to work like this:
- every day it downloads JSON file ( which contains urls, descriptions & links )
- if user is visiting any url from JSON file, pop bubble displaying description and link
- dont bother user after every reload, just one for every page/day
- users will be willing to install extension, no hiding of it is required.
