When I asked a question on SO, today, I noticed that the formatting buttons that used to be there are missing. What happened to them, and will they be restored soon?
Edit Thanks to Eric for pointing out the problem. I use the NoScript plug-in in Firefox to limit the number of scripts that run when I surf the Web. Turns out that, thanks to the changes on the site, I had to allow googleapis.com to get the buttons (and the preview window) back.
