Auto-suspend rarely works

[Jonta]

Used FTS for a few months now, and have rarely been confident that the auto-suspend (I have it set to 3602 seconds right now, experimenting with "what if I turn it up or down a few notches?") works

I've hit [Save] and restartet the browser numerous times since the last time I changed number of seconds, and the checkbox is still checked, and the number is still 3602

Variables that might be relevant:

• Switching windows (counter is only active for window currently in focus? And resets after switching?)
• Computer is asleep (and so counter doesn't count?)
• Old OS (macOS 10.11.6)
• Old computer busy with other things (?)
• Others I'm not thinking of

This isn't that high up on my list of priorities, so I haven't performed any testing yet. Feedback on which specific test to try first is welcome

I saw a few Trello-cards marked as "done", that dealt with this issue. Maybe it's resurfaced

macOS 10.11.6
Fx 75.0 (64-bit)
FTS 3.7.4
