Where can I track the status of features (including in-development) in major browsers?

To leverage the latest web technologies in our applications it is good to know the status of features (like when using caniuse.com) and also the roadmap of major web browsers.

I happened to see this page which shows the roadmap for Chrome web browser.

Is there something equivalent for other major browsers like Firefox, Safari, Edge and so on?

Solution
    1. The MDN repository "contains compatibility data for Web technologies as displayed on MDN"
    2. Can I use "provides up-to-date browser support tables" for Web technologies and features
    3. ECMAScript compatibility tables provides status of ECMAScript support like caniuse
    4. HTML5TEST lets you know how well your browser supports HTML5
    5. WHAT WEB CAN DO TODAY is something like HTML5TEST
    6. Browser Platform Status Tracker tracks engine features
    1. Google Chrome roadmap and features (includes in-development etc)
    2. Firefox implementation and standardization roadmap (seems to have been abandoned)
      See Firefox Specification Positions instead
    3. Microsoft Edge platform status
    4. Safari webKit feature status
    5. Opera (same as chrome)
    1. See Learn how browsers are working together to make it easier to build for the web
    2. See Interop 2022 Dashboard

    Note that Google Chrome, Microsoft Edge and Opera are all Chromium-based browsers that use Blink browser engine.
    Thanks to this GitHub gist for its help.
