As of lately, I have to wait a while, up to a minut or so, after closing sandboxed Firefox, for the sandbox to terminate and auto-delete it's contents.
Sounds familiar to anyone? How can I solve it?
Windows 10 v1903 (64 bit)Sandboxie 5.31.2 (64 bit)Firefox v69.0 (64 bit)
Do you have any antivirus running that may be holding on to the files?Are there any Firefox extensions?Does the issue follow you to a new Sandbox with default settings? What do you see hanging in the Sandbox during that minute? What are the exact repro steps, anything in specific that you are doing to trigger the problem? Or do you just launch FF and immediately close it and see the behavior?
Also, please post your config file (Configure---> Edit configuration. Copy paste the contents in your response).

Thanks for your message.
I am not seeing anything "strange" with your configuration file, and since we don't have repro steps, I won't be able to test this scenario (I tested FF version 69 and no issues so far using a similar config to yours).
- The usual suspects: Do turn off your Antivirus / extensions for testing purposes and see if that changes the behavior.
- Try adding Firefox as a leader program in a new Sandbox with default settings, and test it:https://www.sandboxie.com/ProgramStopSettings#leader
- For your lingering programs, add pingsender.exe (it is not on your list, but it appears for me for a few seconds when I close FF).
I tried disabling Avast but it's all the same. Also, the same is happening on my other PC which has the same version of Windows and Sandboxie but an other antivirus - ESET. The problem is the same: sand box wouldn't terminate for 30 seconds or a minute after I close Firefox. Usually that happens after a longer Firefox session but that's not a rule, it's pretty random.
What I see active in the sandbox before termination is RuntimeBroker.exe, as seen on the pic in my first post. Could that be the culprit?
If I add Firefox as a leader program, when I close it, other sandboxed programs from the sandbox will terminate with it, right? I don't want that.
Pingsender.exe only shows up if I turn on Telemetry in FF, but I have it disabled, so it's not active on my PC.
Anyone else maybe experiencing something similar after the latest Firefox update?
I solved the problem by adding RuntimeBroker.exe to the lingering programs, now the sandbox terminates instantly after closing Firefox.
Hope this helps someone else too.
