@leeloo @Vivaldi Vivaldi could be for me. I am commenting here because the web browser for me does not exist. Allow Manifest V2 extensions; use a different browser engine like Servo, LibWeb, or build your own; and if Vivaldi was truly customizable I could turn off tabs amongst other features.

@Vivaldi
• Manifest V2 extensions won't work but Manifest V3 AI extensions will "Because Vivaldi is built using the Chromium web browser project, extensions available in the Chrome Web Store can also be installed in Vivaldi."

• if liked the Big Tech browser engine Chromium used by Chrome, Vivaldi, Edge, Brave, etc... that would be okay but I am de-googling so no Google Chromium based Vivaldi for me.

• if liked tabs, I guess Vivaldi would be cool, but I absolutely cannot stand tabs.
