This is an off-train fix should be fixed by the new advanced targeting that checks for HAS_PIN

Hi Marius, I updated the experimenter's advanced targeting to include a HAS_PIN check, could you please re-verify in beta!

Hi, Negin! I have tested this issue using the latest Firefox Beta (110.0 - Build ID: 20230206190557) installed on Windows 10 x64 and Windows 11 x64. I can confirm that users are no longer enrolled in the experiment if Firefox is not pinned to the taskbar.
