not sure about swiping but vivaldi definitely does have tab stacking/grouping (customisable) and vertical tabs; librewolf either has it by default since they baked in tab groups into upstream or it’s able to be enabled in about:config! i just don’t know if it’s officially in yet since i mostly use nightly.
These don’t have the tab organization and swiping gestures I like, which is a bummer.
