The Hello world project attached by allowing "unsigned extension" automatically quit with code 0 after a period of time.We have been developing a safari app extension with numerous messages exchange, unfortunately I just couldn't see through a whole trip at once, since it would exit with code 0 after several seconds. There was no clues after commenting and scrutinizing the codes. So I just created a brand new hello world to see whether I can print all the messages I sent. The results are stunning, the hello world progra quit as welll without error or exception. I assume that it would be a built-in mechanism to prevent the app from running without interaction with users. But anyway It really hard for me to debug that messages communication,Does anyone know what's going on here, how can work it out?Thanks !

Before it we have the backgroud wherein we can get notified when a tab closed or opened.And also we can give each tab a identity to achieve the tabmanagement. Can we get that too, It is really helpful! Now, we are trying to go this by workaround like using "getAllWindow" and "getAllTab", and "isEqual" to distinguish tabs, but to find that some times if we refetch the tabs, the very same tab become different. Let alone to reduce or add a tab during the operation, It is frustrated and struggling, could you know there is something we can do ? Thanks!
