After saving sessions:

Waterfox Current 2019.10 (20191023104314), Manjaro Linux.

Hmm … maybe I was wrong to assume compatibility with Waterfox Current 2019.10.

Defocusing from SessionBuddy

I see, now, that some types of legacy extension are allowed (not automatically disabled) but non-functional.

Waterfox Classic 2019.10:

Waterfox Current 2019.10:

SessionBuddy

Without classifying SessionBuddy as legacy: what does it have – in common with legacy extensions such as Session Manager – that allows it to rise 'above the line' in Waterfox Current 2019.10?

@MrAlex94 can we (eventually) answer this question without using acronyms such as XPCOM? Ha
