Hi Michael, hi everyone,
Session Manager extension still works nicely with last version of Waterfox (56.1 at the time of this post, WF still support old-style XUL addons) and replaces gracefully the Tab Mix Plus session management feature that is buggy with FF 55+ and Waterfox. Those two extensions can work together with ease: Session Manager for session management and TMP for tabs management (TMP recognizes Session Manager activity and auto-disables its session management feature!).
But because none of these addons are compatible with FF 57+, I now use Waterfox for months (sorry Mozilla, I've been a very long time user of your products but with your Chrome-replicant FF you lost me)...
