> didn't support some of the most useful Opera 12 features for my workflow (e.g. MDI) I'm still on Firefox for a few reasons but I've been checking it out as it evolves, and been pleasantly surprised with progress over time. There's a few things that I think are inherent to Chromium, that I doubt they'll ever get back; one of these is definitely MDI. But on the other hand, there's also a few things that I believed were Presto-specific (HTML renderer-related, e.g. text-selection of link text) that they have somehow managed to re-implement on top of Chromium, so never say never. > Unfortunately, Vivaldi wasn't recreating that when I tried it. Yeah, Vivaldi is not snappy. But... given the state of browser UI performance today (massively regressed from 8 years ago), it compares favourably to competitors. Which isn't to be sniffed at considering they've added so many things on top of the beast that is Chromium.
