I will wait a little, Gwen-Dragon. I am not happy with it. I use Vivaldi 1.5 again (and maybe try later what you write). 1.5 does great.
It is not only certain video in 1.6-1.8, but also not able to input sufficiant tabs from feedreader or e-mail into the browser and a jump to a wrong workspace when things stall. I thought it was over in 1.8 but it isn't. Chromium and Chrome also have the problem, so:
Yesterday I made a copy of my system, I deleted all Chromiumlike browsers (Chrome, Chromium, Vivaldi) and used Vivaldi-snapshot. That was better in accepting tabs, but then that video did not work.
Thank you very much for the reply and maybe I try in some new Vivaldi-version.
Other question if I may: is here an email notification after a reply?
