From a web page I am viewing in Firefox, I try to view a Quicktime video. The video becomes out os sync or will appear to be stuck for a few seconds (gives a nasty repeated noise) and then starts up again, but out of sync. It begins to get worse if you do nothing. However, if you move the progress bar - even a little- it will straighten out. This does not happen on the same page with the same videos in IE. Any ideas?

This happened

Every time Firefox opened

Hello Lori.

First of all, make sure your add-ons (extensions and plugins) are all up to date. You can manage them by going into Tools > Add-ons. If they are and you still have those issues, you may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check, and except the one plugin you need - quicktime, I think?), to see if Firefox goes back to normal?

If this doesn't help, you will need to contact the plugin's author for support, since quicktime is not developed by Mozilla.
