No particular mouse events are needed, you can even use the mouse over browser chrome and not over the actual HTML document, and Flash will still become visible. I've tried to create a (somewhat) reduced test case and made it available here: ## Example http://roderick.dk/experiments/hidden-flash-crouching-firefox/ ## Testcase on GitHub https://github.com/mroderick/hidden-flash-crouching-firefox For debugging purposes, I've added Flash files that display how long they have been running, instead of the files I originally used when discovering the bug. The original page that lead me to discover the bug is here: http://tdc.dk, but it contains a workaround that detects FF4.0/Win and FF4.0.1/Win and uses fallback content. No detection has been made for FF Nightly though. Reproducible: Always Steps to Reproduce: 1. Load the webpage in one of the following Windows versions of Firefox: 4.0, 4.0.1, Nightly 2011-05-10 2. Observe every 10 seconds the a different 'tab' will be displayed 3. Observe that sometimes, the Flash content will not be displayed 4. If Flash is not displayed, move the mouse over anything that can generate a mouseover event, even the browser chrome will work. Observe that the Flash now becomes visible. Actual Results: Flash is not visible Expected Results: Flash is visible This is reproducible only in **Windows** versions of: Firefox 4.0 Firefox 4.0.1 Firefox Nighly 2011-05-10 on OSX everything seems fine.
