What do sites used IndexedDB for?

Some notes on a survey of what all I find in IndexedDB storage in Firefox. That’s something like cookies, a way for a website to store data on your computer, only in this case it’s a fancy NoSQL database. I’m using it myself and have found Firefox’s Storage Inspector unreliable and limited, so I built my own tool to look through my profile directory and tell me what it finds.

Example report from the tool:            dm_typeahead               20160920      98304
  conversations title
  metadata -
  users name_lowercase, screen_name ONE_SIGNAL_SDK_DB                 1      49152
  Ids -
  NotificationOpened -
  Options -    test                              1      49152

That tells me

So what’d I find?

The tool I built is in this gist.
