Workaround for old Firefox Plugins crashing on Windows 7

I had an old plugin which was working fine in Windows XP. When I moved to Windows 7, this plugin kept crashing whenever opened. After a while, I was able to find a workaround for making this plugin work.
Windows 7

The answer lies in DEP (Data Execution Prevention). This feature was enabled in my Windows 7 machine. After I disable this feature I was able to run my plugin in Firefox. Here is how you can disable DEP in Windows 7.

1. Go to command prompt
2. Execute the command bcdedit /set nx AlwaysOff
3. Reboot the machine (rebooting is required for the above setting to reflect)

Ideally with DEP enabled, if you want to run your plugin, you have to build the plugin with the latest version of Windows SDK.
