Hey there. I just looked back at this old project and wrote a modest update:
- Use fork awesome instead of font awesome for icons
- Fix broken links in footer
- Decrease download size by shrinking icon

You shouldn't notice anything that impacts normal use.

This update is the first in a while, and there are a few changes that you will notice this time:

- New social sharing options! Added Diaspora* and Mastodon
- New icon! It looks cooler now (in my opinion)
- Removed that pesky w3.css that I never really needed

Please ask for more features at https://github.com/masterofthetiger/apod-extension/issues

Mozilla took down my addon and I fixed the issues that they told me to fix:
- Fixed unsafe assignments to innerHTML
- Removed link to JQuery file that no longer exists (I forgot to remove it in the last update

Other:
- Removed permission (storage) which is not being used

There is no changes for the user in this update. Everything works like before. You won't notice a thing.
