I second that !
Just came over to try Vivaldi after Firefox banished Linkman to 'Legacy'.
Linkman support in Vivaldi is a dealbreaker.
And I note all the Linkman posts are mellowing unattended in year/s old history.
Not a good sign of priority activity.
But . . . .
It Works ! In Vivaldi ! Behind the scenes activity must have been happening !
Reloaded Linkman & set my Linkman communication port & Voila !
