Last week, I started playing with the SWT macOS Cocoa port. You can follow all the changes and discussions via bug 502090. I now have a successful build using recent macOS libraries from 10.12.
The last missing piece is support for a Mozilla browser on macOS. This as been implemented using the XULRunner. However, the XULRunner is deprecated and has been removed from most Linux distros (according to Wikipedia).
I’d like to drop support for it completely from macOS. Is there anyone relying on it? If yes, do you have the time/resources to commit to maintaining it going forward?
Please comment on bug 506092.
