By now, everyone reading this knows that Firefox 1.0 has been released. Firefox is, of course, the best web browser currently available. Let's reflect. First it was Netscape. At the version 3 point, IE was preferred. I stuck with IE through 6. And now Firefox my preferred browser. The reasons are countless and frankly I don't care to list them all here. What I do know is that when I'm forced to use IE, web browsing is a much different, much less pleasant experience. Of course, a good deal of that is the result of Adblock. But I've gotten off topic.
My tweak: If you go to about:config, you can set browser.block.target_new_window to true, which prevents web sites from opening new windows. If I want a new window (or tab), I'll do it myself, thank you very much. But after upgrading, it stopped working! A little messing around found the answer: set browser.link.open_newwindow to 1. I'm not sure what that means, or what other values of it do, but it works. So if you're struggling with this issue, give this a shot.
