The CR-Unblocker will get an American Session ID and sets it as your current Session ID cookie. Like this Crunchyroll will think you are located in America and therefore you should have access to all anime you couldn't watch.
Update from January 27 2019:
NOTICE: Crunchyroll recently changed their region detection in some way. Shows in the Queue don't show up anymore and the detail page says the show is not available in the region. However, it is still possible to view the videos when the URL is known. As a temporary workaround there are 3 options:
1) The homepage still shows newly released episodes.
2) When one episode is over the redirect to the next one still works. You can select previously watched episodes from the "Recently Watched" section to the right of the queue and skip to the very end of the episode.
3) Use a VPN to get the episode link, then disable the VPN to let the video load over your regular connection.
While I'll look into this more, I think crunchyroll now requires full VPN, making this lightweight Option less comfortable to use. Sorry, nothing I can change! We can be happy it worked for such a long time and at least for *some* countries there are more shows compared to a few years ago. Thanks for using this Add-on!
