In FF2 everything works fine. I'll attach a simple html page demonstrating the flaw. In FF3 flash overlaps the red bars at the top and bottom of the page. Reproducible: Always Steps to Reproduce: 1. Browse to a page using Flash and html elements using position:fixed. Actual Results: Flash overlaps the html element using position:fixed Expected Results: Html element should be rendered on top of flash. I've tested this on multiple distributions and 2 computers, and it is still present in the CVS version. I haven't tested on Windows though.

confirmed using: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9pre) Gecko/2008051506 Minefield/3.0pre Suggest change OS-->All BTW only the one w/o wmode overlaps the div the rest are fine.

This is just because position:fixed doesn't have a widget anymore. position:absolute always had this issue.
