@sgunhouse That is false, the error is not on their side.. If you check the internet you will find a list of possible reasons for this error.

@leocg Before I used Chrome, but no passwords have been saved in there. As said, the user id and password were last used way back in 2013 and I bought a new pc in 2015, i.e. I started off with a clean system. I removed the 'web data' (see above) and tried a few times. The below, that I got before, is now gone, i.e. no drop down with 'suggestions' anymore. BTW: passwords (Settings->Advanced->Autofill) are controlled by Roboform, but Roboform usually shows a pop-up with an option to either only Fill or Fill & Submit. That wasn't the case here. Anyway, whilst the puzzle as such isn't solved, the problem is... Thanks.

Found it! It was a pop up from Ghostery which in itself is a blocker DOH!
