I have been using QuickTime Alternative for a long time, but onegoodmove is crashing Firefox with the last available version of QT Alternative. And given the developers stopped any further development after Apple requested that they remove the package from their website, I needed an alternative.
Now, I am not keen about going back to the official QT Player, even though the developers of QT Alternative published a guide on configuring QT Player “for optimal performance and user satisfaction”.
I managed to find “QT Lite” (thanks, Google!) which is very well put together, with just the components I need. CoreAVC and CoreAAC are not longer included but that is not a huge issue.
Overall, very happy with this “update”, and Firefox is no longer crashing on onegoodmove. Thanks, whoever put this package together.
