Tor 8.0a won't let me log in to Disqus

I use Tor to comment anonymously on Disqus, but the upgrade to 8.0a does not let me comment. I have no trouble commenting on 7.5, but I cannot comment on 8.0a. I log in as usual, and go back to the comments, but am not logged in. If I try to log in again, it won't let me, but I can't make a comment or vote another comment up.
