After updating the browser on my Windows 10, the same problem. Opera is my preferred browser, but it's so annoying that I had to abandon it and move to Chrome. Developers return everything back! If I click on the icon in the browser in a virtual desktop, I expect that there will be a new clean browser window, but instead it opens a new tab on another virtual desktop!!! What? Virtual desktops are needed to share the work on the problem, as I want on each virtual desktop its own set of links have been opened in the browser.
