Quick time crashes and I have lost almost all sounds/video sound capability with the new ff4.0. I want to remove it and replace it with the previous version until the bugs are fixed.

Maybe wait another day because Firefox 5.0 will be released on June 21 and maybe that version works better.


Make sure that you allow the plugin-container process in the firewall and other security software.

You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.
You can adjust the volume level for each application in that window, so make sure that Firefox is not muted or set at a low level.
You will only see the Firefox program in the Mixer if you are on a website that plays sound.
Also check the volume setting for the plugin-container process.
