I have previously in several HN comments been vocal and adamant about leaving the Mozilla shipwreck before it foundered on the shoals of 57.

And I may have been wrong.

At long last there is meaningful information on addons.mozilla.org about what actually works now, and what doesn't. Looking nowhere near as bleak as it all sounded just a few months ago. I can have my uMatrix, I can have something Flagfoxish, I can open tabs by rightclicking links, I can have meaningful search from context menu. I can have something which doesn't look like Chrome. I may actually give the thing a chance.
