Where does Opera 25 store Extension's data ?

  • Say for example, extension GreaseMonkey (from Chromestore) is loaded with several userscripts. Every time I reopen the browser it comes right backup so its data must be stored somewhere on the hard disk. I did a comprehensive search for keywords within files in Appdata\Local or Roaming\Opera software but it did not return any result. I suppose the data is not readable ?

    For the matter, I would like to recover userscripts I had in a previous installation (hard drive formatted). I have all the files backed up but couldn't pinpoint/recover the scripts.
    I know Opera is stripping functionalities so I have to depend on extensions more and more and it is really annoying that their data is not so transparent and easily backed up.
    Can you please offer some help ?

  • Opera's profile folder/Extensions/Extension-ID/ but not only there afaik as there are, at least, two other folders related to extensions.

    And Opera also stores stuff related to extensions on the Preferences file.
