Detect if own Opera extension installed and disabled using JavaScript

I can detect if my Opera extension installed by setting the new window object property (window.isExtensionInstalled for example) in injected script and checking it in web-page javaScript.

But this is not solution in case the extension is disabled.

How can I detect disabled extension?

Are there features like resources web-access in same manner as for Chrome extensions?

May be some other useful features?

Thanks in advance.

Solution

  • No, there is no such feature.

    By definition, each extension lives in its own sandbox and is not aware of other extension.

    The only chance is to look out of the window (object) and search for footprints (modifications of the window or child objects) of other extensions. If these are forced to stay at home (deactivated), the can't leave footprints..

    Sry for being so figurative ;)
