I always thought that Firefox would be the professional's browser but it keeps failing at the task. Maybe Microsoft could succeed at creating a browser that aims to make office workers more productive? Imagine a browser made to be extended and automated and with deep integrations with Playwright, Node, other MS products. They could even throw a couple of millions at addon devs to port the most popular add-ons on the market to the new browser. Obviously it would also focus on ad blocking, privacy and security but that's the new default for browsers.
