Small FR here - it would be really useful to be able to select which browser I want supplying the custom tab backend for Boost. I’d like to be able to use Firefox or Samsung Internet rather than just dumping everything into Chrome. I don’t always want my random reddit clicks linked to my Google browser history. Previously I’ve used Lynklet to shovel clicks from Boost into Samsung (thanks baked in night mode!) but this isn’t really ideal now that Lynklet is abandonware.
