I downloaded the Mozilla Firefox 1.0 preview release earlier this week, and am troubled to find that the pop up blocker in it is horribly screwed up. The problem is that it wants to block pop ups that are loaded when you click on a link, and doesn’t seem to listen if you tell it not to do that on certain sites. So, for example, I can’t open links to items on Bloglines, or view Yahoo News slide shows. I’m sure there’s a bug that explains what’s going on in Bugzilla, but I’m having trouble finding it. I’ll just assume that it will be fixed prior to the next release.
