Here's a work around for the next time the captcha gets screwed up Install these two add ons: https://addons.mozilla.org/en-US/firefox/addon/cookie-exporter/ https://addons.mozilla.org/en-US/firefox/addon/cookie-importer/ You can install them in Tor Browser just fine. Login to the market and use the first add-on to export your the cookie to a text file. I believe it expires after 2 weeks, so you'll have to do it every two weeks. Then if the captcha is screwed up, use the second add-on to import your login cookie. Works like a charm.
