We hope that you took the time to test Firefox 3.6 on your web sites before the release. If you didn’t, it’s not too late to let us know about issues. Here are a few problems that we’ve seen in the wild so far:
- We’ve seen a couple of issues with the FCKEditor component, used widely on the web. It apparently doesn’t handle dates after 2009 properly (this is the first major browser release in 2010, a new decade!) and it also has some problems with
- People who had the YSlow extension installed saw crashes with Firefox 3.6. YSlow has been updated to version 2.0.6 to fix the issue
- Some Facebook apps were broken by a change we made to comply with the upcoming HTML5 standard. We updated
document.getElementsByTagNameNSto no longer case-fold when doing tag name lookups. (We strongly suggest that you only use lower-case for tag names for many reasons, including this.) For more information, please see this note from Henri Sivonen about what’s changed. Facebook has since fixed the issue in their code, but other sites may also be tripping over this.
We’re looking for feedback on any developer-facing regressions you’ve seen in 3.6 from 3.5. Please comment on this post if you have feedback.
