Comment (by cypherpunks):

 Replying to [comment:5 gk]:
 > Is that reproducible (e.g. by loading a particular URL)? I am curious
 where the NoScript relation is coming from.
 Thanks for taking interest in this. It's a bit difficult to reproduce
 immediately but sometimes when I'm on a page and I ctrl+click on a link so
 that it opens in a new tab, the cpu usage gets to 100% on one core for
 about 10sec and it's taking 20sec or so just to starting loading up the
 page, from the browser console I see NoScript doing its thing (i.e. the
 CSP hack) during that time. (on 8.0a9 of course) It doesn't happen always
 so it's difficult to give clear ways to reproduce other than "just browse
 with safer security setting and ctrl+click on links".
