Update: this should be fixed in the newest version. It uses annas-archive.li instead of the now blocked annas-archive.org. If .li ever goes down, you can change this domain at any time in the add-on preferences.

Original comment: Hi there. annas-archive.org is now down, so the links have indeed stopped working.
I added a setting in the new version that should fix it. Here's how to enable it:
- Go to to "Manage Your Extensions" in settings (Ctrl+Shift+A)
- Click on anna-goodreads
- Click on "Preferences"
- In "Domain", enter: annas-archive.li

Perhaps I can make this the default.

If annas-archive.li gets blocked, you can go to https://en.wikipedia.org/wiki/Anna%27s_Archive to see where it lives, I think that'll keep working.
