Ever since blogs.msdn switched to using those three-digit captchas (which seem like a good idea from all the spam there was before) I've been unable to post comments on MSDN blogs using Firefox.
Clicking the submit button just takes me back to the front page for the blog I'm reading. (No error message and no "your comment is awaiting moderation" type msg; it just navigates up a level and the comment doesn't appear.) Switching to IE lets me post the same thing without a problem.
Anyone know if there's a fix I can apply? Maybe a Firefox setting I need to change. Do other Firefox users see the same thing?
I have Firefox configured not to save cookies after the browser is closed (i.e. session cookies only) but I have msdn.com whitelisted. Can't think of anything else that might break the comment form.
