Firefox 33.1 can't login (nothing happends after I input my credentials)

Hello, please forgive me for being a n00b with bug reporting. I created today an account on keybase.io and I can't seem to be able to login even with FF in safe mode, with all the addons disabled. I get the sliding credentials prompt and after i input them, the login button shows a spinner-like +_ graphic and the page refreshes and i still have the same options of Join or Login on the top right corner.

I also tried the same with Chrome, it worked. Even Android FF worked too. I even generated my PGP key from my MotoG and it didn't take excessively long.

Keep up the good work guys.

No files or tests are mentioned. Start by reproducing the login flow in Firefox 33.1, including safe mode with add-ons disabled, and compare it with Chrome and Android Firefox. Done means the Firefox login completes successfully or the browser-specific failure is identified with a reproducible cause.
