undetected chrome extension with Opera

Question

I have just installed Opera and add three extensions, none of them has this id : chrome-extension://bgpmiljelfnilfcfmoppijdkmccbccel/isolated-first.jst Does anybody know which plugin is hidden behind this extension?

Expect to find the name of a chrome extension or opera plugin I find when I check ajax request in the navigator network panel

Answer 1

This seems to be related to one of Opera's integrated extensions, which would explain why it isn't being displayed in your extension list.

Opening opera://extensions/?id=bgpmiljelfnilfcfmoppijdkmccbccel should display the extension's settings page which would provide you with more details about this extension.

Opera has installed hidden and non-removable extensions like this for promotions in the past, this forum post lists some of them.
