Can't log in with Firefox
Whenever I try to log in with Firefox - either by pressing the Sign up with Facebook button or by entering my username and password - it just takes me back to the log in page. I have already tried deleting my Duolingo cookies, but it did not help. I can log in fine with Chrome. What could be going on?
I've been having the exact same problem as described above the entire time I've used Duolingo (~6 months). I'm on Windows 7, I've deleted my cookies, de- or reactivated all add-ons, whitelisted Duolingo in AdblockPlus, etc. Like clpm, I have to use Chrome if I want to ever use Duolingo, and while it sounds rather spoiled to complain about having to use a different browser, it represents an unnecessary annoyance. Given that learning a language often requires willpower to begin, being unable to use the site on the only browser I actually use just makes summoning the willpower that much more difficult sometimes.
It seems a little disappointing that this problem, which at least a few people are suffering to a severe degree and has been going on for over a year, has gotten no response other than the unhelpful "clear your cache."
Is there anything I can do to make Duo work on Firefox?
