[Enhancement] Improve background CPU usage

[jmbreuer]

Abstract

TreeStyleTabs seems to busy-wait/busy-poll stuff all the time.

Steps to see the situation

1. Have a browsing session with, in my case, 644 tabs over 35 windows; otherwise completely idle (most of those tabs are 'discarded', see AutoTabDiscard)
2. In about:processes, see "Extensions" taking up nearly 100% of one core (i7-6700HQ)
3. Click on the conveniently located "Profile all threads of this process for 5 seconds" button of the Extensions process
4. In the profile result, see updateTimeoutTimer in moz-extension://6efa3d93-bed2-4dff-a92a-064725d94b45/common/sidebar-connection.js:165:31 as the 'culprit'

Expected result

Idle CPU usage of below 30% ideally.

Actual (present) result

Idle CPU usage of 70% - 115% pretty much all the time.

Additional remarks

I'd be happy to know about a tunable where I could trade off this CPU usage against how quickly TST reacts to new tabs or such (which, by the way, already is noticeably slow for me - but if that is 'because' or 'despite' of this issue, I cannot say).

Environment

• Platform (OS): Gentoo amd64
• Version of Firefox: LibreWolf 118.0.1-1
• Version (or revision) of Tree Style Tab: 3.9.17

Could you try larger value for heartbeatInterval, for example 10000 ? The insternaloption is configurable via TST otpsions => Development => All Configs.

[piroor]

I've increased the default heartbeat interval to 5000msec (5sec) to reduce CPU usage.
