Secure iMacros

I know that you can obfuscate macros, so the user can't see the script or change it without password, the file is transformed from .iim to .iimx, but you can't use .iimx files with the browser add-on, is there another way to secure the file and play it through the browser? I just want that nobody can see the script, so no password protection to use it

I find this very suitable
