The past week or so, LJ has been acting up for me--any time I clicked on a comment, cut, or just about any link at all, I had to click it 3-4 times before it would actually load. It turns out that LJ's using some new redirect scripting and NoScript was screwing it up in a silent/invisible failure type way. Apparently I missed the kerfuffle about the last time they tried something like this (since it didn't break the site, I didn't notice).
In addition to accidentally breaking the interface, the script on an EXTERNAL site (outboundlink.net) logs data from every link you even mouse-over, anywhere on LJ, INCLUDING PRIVATE POSTS. Just in case anyone reading this is interested to know that.
Read about it here, including a console command to opt-out which seemed to fix the problem for me:
