Kann sein, das in Q1/2020 Sophos Vivaldi einbindet. Bitte auch dies lesen: https://yngve.vivaldi.net/2019/10/24/sophos-an-update/

@nomenclator On Vivaldi F5 reloads from cache and it depends on server's caching and expiration setting when a new page will be loaded by browser. Ctrl+F5 will reload without cache.

@collin-obol Did my advice typing thisisunsafe had helped you?

you're right, I see it as well now! Thanks for the quick reply!

@anrdaemon We know, what @Pesala is saying is that typing and pressing Enter uses the same tab, thus pasting and pressing Enter should also use the same tab so it's consistent. And that's the name of the feature, Paste and Go, not "Paste and Go in another tab". And as I said, that's an extra setting also in Presto Opera, even Presto default is like Vivaldi. So we came to the conclusion that it's not a bug, but a feature request.

That is not a Vivaldi bug, same on Chromium with uBlockOrigin; uBlock blocks and MS page fails.

Avira Support told me the setup.exe is ok. False positive. I close your reported bug,

@luetage I believe he is saying that he was told it was a new computer when buying, but now it turns out it was second-hand (and incorrectly erased by merchant). Hence the mention of compensation.
