[Bug] High CPU usage on Firefox 132.0.1

[mesvam]

Abstract

Seems to causes constantly high CPU usage on Firefox 132.0.1. May be related to recent Firefox update? Disabling extension lowers CPU usage.

Steps to reproduce

To be determined. Does not consistently happen on all profiles, and I'm still trying to find the root cause.

Issue does not happen on a fresh Firefox profile.

On the profile where this occurs, resetting TST settings doesn't fix the issue.

Expected result

Actual result

Environment

• Platform (OS): Windows 10
• Version of Firefox: 132.0.1
• Version (or revision) of Tree Style Tab: 4.0.23

Probably not a TST issue, but a Firefox issue, as I just observed the same thing on another extension.
