Works just fine here. Any particular url ?
(In reply to comment #1) > Works just fine here. > Any particular url ? > Anything with flash. youtube.com, for instance. Looking through my genlop logs, I see that I recently upgraded www-client/mozilla-firefox from 3.6.3 to 3.6.4 (and correspondingly net-libs/xulrunner from 1.9.2.3-r1 to 1.9.2.4). I'm rolling back that update to see if that fixes the issue.
after performing the following two downgrades: www-client/mozilla-firefox-3.6.4 -> www-client/mozilla-firefox-3.6.3 net-libs/xulrunner-1.9.2.4 -> net-libs/xulrunner-1.9.2.3-r1 the problem went away (I can view flash videos again). Further, none of the error messages from Firefox mentioned in the original post appeared. Unfortunately, I don't know of any workaround other than adding the following line to /etc/portage/package.mask >=www-client/mozilla-firefox-3.6.4
Works fine here, on x86 too. While OOPP may matter, average youtube flash plays fine, even though there are few sites that don't work (upstream knows about some of them).
I confirm this problem, and this is a major bug.

You can disable it locally as flash will never be compatible I am sure. To disable open about:config and change dom.ipc.plugins.enabled.libflashplayer.so;true to false. I will not do this on the distro side as there are many of us that do not use flash.(In reply to comment #5) > I confirm this problem, and this is a major bug. > This is not a major bug, this is what happens when you use a binary plugin that we have no control over. Closing bug invalid.
However in my case a downgrade of www-plugins/adobe-flash-10.0.45.2 resolves the issue. @Bjarni Herjolfsson Can you please follow what Jory A. Pratt said and report?
Yes, this Firefox config change has fixed the issue (In reply to comment #7) > However in my case a downgrade of www-plugins/adobe-flash-10.0.45.2 resolves > the issue. > > @Bjarni Herjolfsson > > Can you please follow what Jory A. Pratt said and report? >
Thanks. Upgrading.
Apparently that's not working. dom.ipc.plugins.enabled, dom.ipc.plugins.enabled.libflashplayer.so, dom.ipc.plugins.enabled.libnptest.so set to false,
