As soon as removing the <param name="wmode" value="transparent"> from the object tag the flash will be integrated as expected and as it has been in FireFox2. Reproducible: Always Steps to Reproduce: 1. visit http://chipdisc.de/new.html or any other page having a flash movie placed with <param name="wmode" value="transparent"> in the object tag 2. click anywhere inside the flash movie Actual Results: the focus ring becomes visible ( the "active element"-frame that is for example drawn when clicking a linked image ). http://chipdisc.de/e.jpg http://chipdisc.de/e2.jpg http://chipdisc.de/e3.jpg Expected Results: flash movies using transparency should be flawlessly integrated into webpages solutions tried that did not fix it: 1. adding css-properties like outline: 0px; border-style: none; 2. disabling JavaScript 3. setting browser.display.focus_ring_width = 0 in about:config 4. disabling all FireFox addons 5. visiting the page with a clean profile via ProfileManager

Confirmed on Windows Vista. Works: 2007032721 Fails: 2007032722 Regression window: http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=2007-03-27+20%3A00&maxdate=2007-03-27+23%3A00 Seems to be caused by Bug 375508.

Setting outline: 0px; on the object element, works for me. After that, the focus outline doesn't appear anymore when focusing the object (tested using current trunk build).

the bug seems to be highly OS-dependand. I was using WinXP, somehow the bug doesnt appear in Linux FF. Might be that it can be fixed by adding outline: 0px; in Vista, but at least for my configuration it does not help.

_on the object_: outline: 0px; solves it indeed. i was just trying to apply it to my wrapper all the time, not for the object tag itself! Thank you for your time.

There is an object:focus rule in html.css that is causing the focus outline: http://mxr.mozilla.org/mozilla-central/source/layout/style/html.css You can only see it for windowless plugins, as the reporter said. The focuse outline doesn't happen for embed:focus (no css rule for that in html.css). I don't think web developers expect these kind of focus outline for plugins (Flash, etc), so it seems to me it is best to remove the object:focus selector.

So like this. If this isn't a good idea, then I guess an embed:focus selector should be added, but I don't web developers are expecting these kind of focus outlines when Flash plugins get focused.

Hmm, applet:focus should probably be removed then, too.

Comment on attachment 333225 [details] [diff] [review] patch r+, and please change applet:focus as well

And also with the applet:focus selector removed as suggested.

The applet reftest was failing, probably because the plugin is being loaded at random times, which can make it look black or white.

Should this really be changed for object:focus for all objects?

Also, authors complain about our showing focus rings a lot, but showing the focus is good for users in at least some cases. Why should we respond to this particular complaint by removing this particular subset of focus rings?

Ok, perhaps this should just be left alone then. But there is no embed:focus rule now, which is a bit strange. Or perhaps the rule should only not apply when <object> invokes some kind of external plugin?

This has been tagged for Regression and or Closure. "the focus ring becomes visible" Not occurring in Nightly or Release - appears this has been fixed.
