Why can't I get Flashplayer to work on Firefox?

Hi, I don't know the problem you are having as I've never heard of that. You need to Uninstall first. Try this method and if you don't want Flash Player Installed in IE, then skip that part.

Download and SAVE to your Desktop the Uninstaller:

Download and SAVE to your Desktop the Installer for IE- use the EXE Installer

Download and SAVE to your Desktop the Installer for FF- use the EXE Installer for plugin based (from the same site)
Close all browser windows, you only want to be looking at your Desktop.
Disable any messenger services, as yahoo, msn, etc in the system tray(area near the clock)

If you use Norton or McAfee Anti-Virus, you would want to disable that also as they can block the Shockwave Flash Object.

Be sure to use the Administrator Account.

Run the Uninstaller and when finished, Reboot(restart) your computer.
Check to make sure the Anti-Virus is still Disabled
Run the Installer for IE, Run the Installer for FF and when finished, Reboot.

Then go to this test site and test each browser:

You may want to print these instructions to make it easier to follow. If you have any questions, let me know.

See if that works better.
