An extension that gets url of all tabs from a current window(browser) and sends the list of urls to a host application.
The extension uses 2 different events
1. On Tab Update - whenever a user changes the url of a tab or create a new tab, extension gets all urls from all tabs in the current browser window the user is using and sends the urls to a running host application.
2. On Tab Destroy/Removed - the same thing happens with the 'on tab update' event, but happens only when a tab was closed
