(splitting this off from https://orionfeedback.org/d/960-sync-browser-data-between-ios-ipados-and-macos/22 per @Vlad's suggestion)
I would like to have a unified browser history across all devices. I currently have this with Firefox + Firefox mobile and losing this feature is the only thing keeping me from switching to Orion. I don't see the need to have history items associated with a particular device - it's all just history to me. I would also definitely not want history search to be segmented per device (so that I'd have to search history from each device to find a particular page that I viewed before).
