It would indeed be a cool feature, and it will draw attention to Vivaldi. But to be fair, there are already some great ad and tracking blockers out there. But a standard feature would be nice. I would say, look at Ghostery for some inspiration.

@grimeton The shown URL is the internal representation of Vivaldi browser's startpage. And you can not open internal Vivaldi pages on Firefox!

Thanks for the warm welcome & the advice. ^^

@mib2berlin I agree. Every once in a while, I would like to import my Bookmarks from another browser but the separators are not carried over in the HTML file. Either way you look at it, this is a laborious process. I upvoted as well.

@Pesala Not good news. I've already tried the workarounds you suggest and they are not handy or suitable for my needs. I'll stick to firefox then. Thanks though.

@izacks It may claim to be rejecting 3rd party cookies but under the current schema it's not, unless you are accessing EVERYTHING currently on vivaldi.net and none on vivaldi.com (which I think may now be possible.) It is not, or should not be, possible to log in on two linked domains unless cookies from both are accepted. It is a security vulnerability to do so. It is just possible, I suppose, that firefox is treating them as un-connected domains, which it should not - as they cross-reference each other.

@dypsis @waterfire Also switched from FF to Vivaldi. I also use Session Buddy (https://chrome.google.com/webstore/detail/session-buddy/edacconmaakjimmfgnblocblbcdcpbko) as my session manager. Not perfect but a good alternative IMHO.

@racingtortoiise Well, I'm pretty sure a touch fix will come, but don't know when. A lot of touch users still uses 1.9 stable which simply works.

@greenenemy I am glad that's the direction browsers are going, even if some old extensions won't be updated or if one occasionally doesn't work well in all of them. Thanks!
