Once used it, but doesn't function any longer in more recent Firefox versions (e.g. Mozilla Firefox 113.0.1 - on Ubuntu 22.04.2 LTS), whilst eid does work in e.g. Google Chrome. So, middle ware, driver etc okay. When you leave this add-on activated randomly in recent Firefox versions, it causes an annoying popup each time you open the browser. Would have given it more stars before, but not any longer, alas (and alas there don't seem to be any alternatives available). That said, I understand programming sth like this is not easy as the Belgian eid concept in itself is quite a mess. At least, a challenge.. -- P.S.: doesn't work either when I shut off WebRTC (enable), ABP (disable), 'cookie monsters' (disable) and what not ,P.
