Simply Download & Save stories from Facebook, Instagram, and WhatsApp.
It's simpler than its name.
With Story Saver, you can download any story from Facebook, Instagram, and WhatsApp by a simple click.
Update 20th Aug: Fix Facebook problem.
Story Saver allows you to save photos and videos stories.
All you have to do is installing this extension, an icon will appear at the top-left corner of the browser,
Click on that icon and whoosh the story will be downloaded, Oh and another thing the extension will rename the story to something readable ;)
If there's anything wrong with the extension contact me on my email:
