So for a couple of weeks now, I've been getting a "Malformed Request" exception thrown in my face when I try to upvote a video. Not every single time, mind you, but in more than 70% of cases. It occurs on fully loaded pages as well on partially loaded pages, on the main page as well as a video-specific page. Soft/hard refresh, browser reboot, add-ons disabled, nothing works.

Comments and comment upvotes, video submissions, everything seems to work just fine - except voting on videos.

FF 21.0, AB+, NoScript, Ghostery - basically the same setup I've been using all these years.

So, anyone else suffering from this or is it specific to my "unique" setup (as in crappy connection, etc)?
