Firefox 1.5 is out (as if you didn’t know, yet). Get it while it’s hot. And if you are still using a certain other Web browser (Internet Explorer) then switch now.
And now it’s time to test out some CSS 3 features. Apparently Firefox 1.5 supports that partly.
A full changelog since 1.0.7 is available.
Update: I tried out CSS 3 columns in my blog. Works fine with Firefox but sucks in my current layout because the text is narrow enough already for good reading. But looks quite good for example in Robert O’Callahan’s weblog. One problem is immediately evident, though. Reading a long article requires you to scroll up again when you reach a column end. Read for example Frame Display Lists and tell me if you dislike it as much as I do. But of course, if you browse his site in any other browser than Firefox 1.5 (and other Gecko 1.8 based browsers) you won’t see any columns (or so I would assume).
