Remove Application Rules for Sandboxed Apps After Sandbox Flush

1. What actually happened or you saw:

1 - I ran a unknown app in sandbox, it tried to open Firefox. (Browser Opened in sandbox)
2 - Sandboxed Firefox tried to access a website, I blocked this vith firewall alert
3 - This block rule automatically added to application rules under firewall settings.
4 - I refreshed the sandbox and sandboxed app removed and sandboxed Firefox browser closed.
5 - but the application rule (under firewall settings) for sandboxed app and sandboxed Firefox still there.
6 - I used “purge” button and some of those rules removed.
7 - Purge button only removed the non-exist files’s rules
7 - But Firefox browser rules are still there and I cannot reach any website with normal Firefox because of this rule.

2. What you wanted to happen or see:

When I used the “refresh sandbox” for sandboxed apps, all created rules for sandboxed app must be deleted, too. Even those Firefox rules…

3. Why you think it is desirable:

I have to delete those rules for my browser by manually. It will increase the usability of firewall.

4. Any other information:

My browser is Firefox and I am using latest CIS.
