I frequently have both Safari and Webkit open at the same time. I find when I launch Webkit, it restores certain tabs - either the ones I currently have open in Safari, or the ones I had open during my previous session (I haven't done a thorough test to tell) - even though I have my preferences set so that it should not. I know Safari and Webkit share some common resources and I wonder whether Webkit is using my current Safari session as a source for opening tabs when I launch Webkit. I'd rather it not do this - I like a "clean slate" when starting a browser. Is this a bug? If not is there a way to change the behavior? Thanks
This is expected behavior, as WebKit is just the same Safari binary running with a different set of WebKit frameworks. Once can disable the behavior of re-opening windows after application restart globally via System Preferences.
Created attachment 200215 [details] screenshot of system preferences showing settings should prevent restoring previous tabs
System Preferences - as indicated in the attached screenshot - are already set NOT to restore tabs or previous windows on launching applications - which contrasts with the behavior I am reporting. The bug is still unresolved. I do have Glims for Safari installed, which modifies some Safari behaviors - but the "Restore Tabs at Launch" option is also disabled in Glims.
OK, but even if my suggestion is incorrect, this is still not a WebKit issue. Windows are re-opened by Safari.
