Whenever I boot up the computer Flash Player will not function
in Firefox unless I quit the browser and reinstall Flash Player.
It will play with Safari however. If I've done something in my user files, I don't know what it is.
I went to disc utility and repaired permissions as suggested. This did not resolve the problem.
You could try booting in Safe Mode and repairing there.
- Reboot, hold command + s till you see black screen with white text
- type fsck -fy into the prompt
- type reboot when activity finishes.
It's a little unrelated, but search for 'flash' on this page (looks like flash has a problem validating input):

Search for 'flash' here too. Looks like the 10.4.11 update was supposed to fix a flash security issue and your update may not have taken hold correctly:

And you've got a powerful enough computer so it's probably not that:

Let me know if Safe Mode helps fix it.
