User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:5.0) Gecko/20100101 Firefox/5.0 Build ID: 20110615151330 Steps to reproduce: Was experiencing a problem in jquery, but it seems due to delegation to querySelector all. Created a test page and verified that CSS and querySelector all give me the same results for an nth-child(4n) style selector in other browsers, but not in FF 5. Actual results: CSS appears to match other browsers (and spec) but querySelectorAll results in different matches in FF5. Expected results: CSS and querySelectorAll should have the same result for the same selector.

Argh. This is a bug in the nth-index cache. What happens is that we only have cached values for the <div>s and we end up adding 1 to the previous cached value we find. That's broken, of course. In Gecko 2.0, we only looked at the immediate previous sibling, so adding just 1 was correct. We should get this fixed on aurora (Fx6) in addition to m-c, I think.

Comment on attachment 542219 [details] [diff] [review] Fix nth index cache to work correctly when nth-child selectors are only applied to some elements of a child list. Requesting approval to land this on aurora. This fixes a regression in querySelector handling of the various nth-child and nth-of-type selectors (as well as handling of actual selector matching in some cases) that we unfortunately shipped in Firefox 5. The fix is very very safe, and the old code is clearly wrong....
