@rseiler I still have Defender turned on, but I have the cloud protection turned off. Though with the new Creator's Update, I'm not sure cloud protection is a part of W10 anymore. Either way, I have only the basic Defender protection, with nothing added.
Would it be too laborious for you to annul all the upvotes you have bestowed upon me, on this topic, as such a gracious and kindly favor?
As much as it has been recommended not to give importance to this question, I have my sensitivity very peculiar and I do not feel comfortable nor happy with the excess, caused by the user Forte95 to have canceled the downvotes that he had given me.
If it can not be done, I can survive with it, but always with some discomfort, no matter how small.
I don't know whether this can help to identify/solve the problem or not, but I've also noticed that Internet Explorer, Microsoft Edge and Opera 12 are downloading Vivaldi normally unlike Vivaldi, Chrome, Opera (without VPN) and Mozilla Firefox.
This site seems to be using a very primitive method of disallowing browser with incompatible user-agent strings.
Try using an extension which fakes your user-agent. I'm using User-Agent Switcher for Google Chrome but I had to edit the "Chrome on Windows" entry first, as it uses an outdated string. Here's the one that I used to pass through that "outdated browser" warning message on flowkey (I haven't tried the site's functionality though):
Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36
I'm coming from Firefox, which I used from way back at Firebird and Phoenix, but it started to get bloated and laggy so I started shopping around for a replacement. That was kind of a big deal for me given how long I had used it. I can't remember exactly how I found out about Vivaldi but I gave it try back just before 1.0. I liked it but it didn't seem quite ready for prime time so I waited and watched.
Now I'm using it full time at home. I'm very pleased. It's completely intuitive and very, very powerful. I'm not sure what I think about having an email client in a browser, but I really want to give it a try. Seems like it would kill two birds with one stone. I'd like to join in giving my thanks to the Vivaldi team. This browser is only going to get better and better.
Well, I just had a look and I think it's interesting.
I know it's only a small poll, but I think it's quite impressive to be almost equal with a well-established browser like Opera.
Vivaldi is now my main browser (since the last Opera update resulted in so many problems for me) and I look forward to watching it develop.
