Now, the really cool thing about Firebird is that it supports a very clean and open plugin technology, and there's a lot available for it. Last week, I picked up Link Toolbar and LinkIt, which support the HTML concept of "related pages" -- an idea that has been in HTML for ages, but which has been mostly ignored by the big-name browsers. The Link Toolbar uses the links that are explicitly in the pages, and LinkIt tries to suss out other pages that might be related.
So I'm sitting here reading LJ, adding a couple of new friends, and I've just noticed that the "Next" button does the right thing when I'm reading comment pages! That is, if I start reading the comments on an LJ entry, and I press the "Next" button, it takes me to the full-comments view of that person's next entry, which is exactly what I want it to do. Neat -- I always like softwares that DWIMs properly...
