Chrome comes bundled with FlashPlayer so you may need to re-install FlashPlayer in order to make it accessible to other browsers.

For instance on my laptop, here's the path to Chrome's bundled FlashPlayer plugin

 /Applications/Google Chrome.app/Contents/Versions/8.0.552.215/Google 
 Chrome Framework.framework/Internet Plug-Ins/Flash Player Plugin for Chrome.plugin

Here's the path to the player I've downloaded

 /Library/Internet Plug-Ins/Flash Player.plugin
