WTF!? Having to restart browser to post!

It never fucking ends with this site's screwy behaviour, I just get these random stretches of normalcy that offer the false promise of hope. For the last week or so, every single time I try to post a picture, after I select it I'm kicked back to the screen where you choose between uploading or linking, and it wont't work properly until I GET that screw-up and the force quit firefox and restart. Even if I expect it to happen and I force quit/restart before even making the first attempt, it's still like "nope, I'm still going to fuck this up and make you quit/restart again, because I demand the stupid ritual of it all." Fucking ridiculous.
