Questions

Do Firefox add-ons work in Kort?

Many do. Kort installs add-ons from addons.mozilla.org and shows their permissions first. Add-ons that rely on Firefox-only APIs will not work.

Why WebKit instead of Firefox?

WebKit is Apple's engine, the one inside Safari. It is built for Apple hardware, light on memory and battery, and patched with macOS.

Can I import from Firefox?

Yes. On the Mac, Kort imports bookmarks, history, open and pinned tabs, tab groups and saved addresses from Firefox, in one step.
