Vivaldi is so new as a browser it still has its training wheels and dreams of a great life to come. It plans to be across device and it will be supporting onboard Mail. I have only tried it since yesterday and have just joined the community so I am less than 24 hours into this and I am using it as my preferred browser. The only issue I have had is it would not type text on the login page for one site I needed for school this morning when I was on my MacBook. Everything else has been fine on Windows and Mac. It also runs on Linux so it’s completely cross-platform and that is how things should be these days. It is a stripped down browser and designed to be efficient. No argument there. It is amazingly fast and very uncluttered. I am used to a tool bar so I have had to retrain myself and have caught myself out a couple of times looking for my toolbar links. Old habits die hard! I like having the bookmarks at the side. I like what it offers as preloaded site bookmarks in different categories both when I run it in French and English. It simplifies everything without compromising on speed. Pages load ultra quickly. Mostly it operates from a slim sidebar but there are settings bottom left and ,bottom right ,you can stop the browser from loading images and become even faster. The thing which I appreciated the most at school on my whiteboard was the fact I could increase the size of the web page text by using the slider bottom right. It made one lesson so easy because we were working from a French website and to be able to enlarge it just by sliding and then work from that image on the board made for a really good teaching option. If you go to the Vivaldi site you can download the tech preview and then be a part of the community if you want to . It also explains just how much of an open source collaborative effort this new browser is. 2015 at last. You can find them on Twitter @vivaldibrowser.
