Safari v67 hit the ether yesterday and it is very close to being complete. The forms auto-fill and tab functionality are now within the preferences and work really well. Stability is solid and speed continues to be excellent.
One thing I would like to see as an option is open links from other applications in new tab in addition to new or current window option there now.
UPDATE – the bug that leaves a floating dialog box open after the window fails to load seems to be fixed. Now if I can just figure out how to kill the java console…
