Also from Jamie Zawinski yesterday: Mozilla’s Original Sin
Some will tell you that Mozilla’s worst decision was to accept funding from Google, and that may have been the first domino, but I hold that implementing DRM is what doomed them, as it led to their culture of capitulation. It demonstrated that their decisions were the decisions of a company shipping products, not those of a non-profit devoted to preserving the open web.
Those are different things and are very much in conflict. They picked one. They picked the wrong one.
Vivaldi is closed source and based on Chromium (albeit modified), so it does not sound all that appealing. As long as uBlock origin, NoScript and Tampermonkey can unleash their full potential in Firefox, I’m likely to stick with it.
