After emerging mplayerplug-in, Flash 9 plug-in detection failed to work in Firefox 2. The browser prompts for a Flash player plug-in to be installed "Additional plugins are required to display all the media on this page". Reproducible: Didn't try Steps to Reproduce: 1. emerge Firefox 2. emerge net-www/netscape-flash open a Flash page in Firefox (like Youtube.com) 3. emerge mplayer 4. emerge net-www/mplayerplug-in open a Flash page in Firefox (like Youtube.com) Actual Results: Firefox stopped detecting the Flash install and prompted for the plug-in to be installed Expected Results: Flash should have worked since it has been properly installed and configured
[SOLVED] Just restart Firefox and both plugins work together.
Reopen to resolve properly.
