Vivaldi 7.0 is full of updates to give you more control over your browsing, with Instant Sync across devices, a revamped start page with Top Sites, and the all-new Tab Stack Pane.
For some reason, this update kept crashing on my Linux installs. I’d get to the point of choosing a protection level (during setup) and as soon as I clicked continue (or whatever the button below was labeled), Vivaldi would crash. Couldn’t get it past that point unless I just clicked in the address bar and just navigated to any random site while that selection page was still active.
