@mmphosis@mastodon.social @Vivaldi@social.vivaldi.net Vivaldi allows manifest V2 extensions, but they don't have the manpower to keep them working once upstream removes the code. The tab bar can be turned off. Using a different browser engine basically means a different browser, so if that's a requirement, then no, Vivaldi is not for you. As for building their own browser engine, again, they don't have the manpower. You could try building your own browser - you're probably the same number of developers short of having the manpower to pull it off as they are.
