When Firefox (my default browser) is started by clicking on the VPS update notification popup's "More details >>", Script Shield will show no activity. Close Firefox, restart it normally and Script Shield will start showing activity in the AvastUI.
This is completely repeatable for me. After the above incident, close Firefox again, recall the above popup again by right-clicking on the Avast tray icon and selecting "Show last popup message". Click on "More details >>" to reload Firefox. Script Shield's count will no longer increment in the AvastUI, as it's inactive for Firefox again.
If Firefox is already open, clicking on "More details >>" in the popup opens a tab in Firefox but does not stop Script Shield. In fact, that update page incremented the Script Shield count.
I used this forum for the tests, as it normally shows Script Shield activity.
Edit: Has anyone tested this? Is anyone able to reproduce the effect of starting their default browser (hopefully Firefox) from the Avast VPS update notification popup, and then checking if Script Shield is working during that browser session?
