Try it anyway. From all the browsers that don't have your key extensions, Firefox 57+ might still be the best option. It's still greatly customizable via userContent.css file, and there's a lot of motion to improve the abilities of WebExtensions. Thanks to that I've brought back vertical tabs on Firefox 57 that now look and work even better than before - something I wouldn't be able to do on Chromium at all.
