As I feared, ongoing development of Firefox's own inferior vertical tabs feature has made the TreeStyleTab plugin unstable and the author himself does not recommend hiding the native Firefox tabs due to features he cannot emulate in his plugin.
So with a heavy heart and after almost 18 years of use, I disable it, and wave goodbye to nice trees of vertical tabs. 😢
