If you use Mac then you can consider Orion by Kagi (natively built with WebKit) which supports both Chrome and Firefox extensions (experimental).

(I personally use Firefox since I feel it's a much better browser (especially thanks to Firefox Multi-Account Containers), so can't comment on quality since I just tested it briefly.. but I do use Orion as my main browser on iOS where it's amazing.)

I recently switched to Orion in my company Macbook (from firefox, which I use everywhere). It's good enough... but it's not great. I've had at least one site broken even in compatibility mode. I am very frustrated by poor mouse support: unable to drag-and-drop URLs to your bookmark bar, or bookmarks within your bookmark bar (and when I imported my bookmarks, for some reason they were scrambled inside their folders). Other than that, though - it's a browser.
