Salut @lttl60 ,
Le Webmail de Vivaldi, basé sur RoundCube, dispose d'une fonctionnalité d'import/export des contacts (au format vCard ou CSV, je crois). As-tu essayé ?
Il doit aussi être possible d'accéder au calendrier de Vivaldi.net (en lecture seule) via un client supportant le format iCal. L'url est indiquée dans les réglages de calendrier. Pas testé, personnellement.
Sorry Jon if i appeared harsh. I still use Opera 12.18 as my main browser and m2 is unmatched (till m3 comes out i hope) but i cant shake the filing that the core is rotten and by core i mean chromium and it will byte us all in the ass some day.
For that reason iv wrote that i admire you and everything you and your team are done and are still doing,but iv been with Opera from the beginning and i still cant believe that all your hard work (Opera 12) is just siting on some server because some stupid laws and more stupider decisions when even today without updates for many years now its still the best and fastest browser.
What i m trying to say is that at some point when chromium decides that this or that is not needed i will have a heart attack 🙂 I wish i was an optimist like you.
You are my Hero Jon!
