Browser activity allmost not reported (Firefox, linux)

[1u]

OS: Linux Mint 22.2, Cinnamon
FF: v.145.0
AW: v0.13.2
AWWW: v.0.5.2

As you see in the screenshot, I'm actively using Firefox, but it's not reported concisely by the AW watcher Firefox plugin. So only some minutes instead of hours are shown in the Activity/Browser tab.
Is this a bug or what am I doing wrong?
Any help?
