For us who still use a PowerPC there is a way to utilize the new Flash Player 10 and keep your Flash Player 9 Debug Version for…well, debugging.   Flash Switcher is a Firefox extension that allows you to switch between different versions of Flash Player.   The key to getting the different versions of FP working together is to uninstall each version after you save it to Flash Switcher.

1. Install the Flash Switcher extension.
2. Save your current Flash Player version.  Firefox > Tools > Flash Switcher > Save as…
3. Run the Flash Player uninstaller.
4. Install a new version of Flash Player.
5. Repeat Step 2 & 3.
6. Select a Flash Player to run using Flash Switcher.

That’s it!  Hopefully, FP10 Debug for PPC will be released soon.
