Hi i have an extension who works under chrome, Firefox and opera.
What i did for my chrome extension is, this i created an external little app EXE (windows),
when i launch my app on my desktop the app write reg keys.
Those registry keys prevent the user to remove/uninstall my add-on my add-on is a protection tool against adults contents & dangerous urls, it also work on incognito mode and guest mode is disabled, also creating a new empty profile use the add-on, so its 100% protected!
when my app install those keys and when i start chrome, my add-on is installed,
i would like to achieve the same on Opera.
It is possible ?? because Opera is based on Chromium !
