FlashSwitcher and Firefox 3.6

Those of you who frequently debug or test Adobe Flash applications may have stumbled across the great Firefox Plugin “Flash Switcher” by Alessandro Crugnola. It is a great plugin that allows you to change the Flash Player version used by your Firefox in order to see how your code behaves in, for example, older or non-debug versions.
Anyhow, ever since I have upgraded my Firefox to version 3.6 on my Windows XP and Windows 7 machines, FlashSwitcher kept throwing “NS_ERROR_FILE_ALREADY_EXISTS” errors when trying to switch to another Flash Player Version.

Here’s what I did to fix this bug:

I edited the os.js in c:\Dokumente und Einstellungen\{username}\Anwendungsdaten\Mozilla\Firefox\Profiles\{yourProfile}\extensions\flash_switcher@sephiroth.it\content\js so that it deletes the old flash plugin file prior to copying the selected one. You may download my Version of os.js here!

Obviously – this is happening on your own risk. Promise to create a backup of your old version first, and not to sue me if it kills your browser

I am just saying that this works for me in Firefox 3.6, Windows XP and 7, and version 2.0.2 and 2.0.3 of Flash Switcher
