I use Brave pretty much just for that purpose, while I use Firefox to browse everything else.
There isFirefox PWA, but it feels like such a shitty hack (don’t get me wrong, it’s not badly made, but they’re forced by the circumstances to make a setup process that is one big headache) that I’d rather have a browser that has official and solid support and it also doubles as my browser to test web content on Blink, so it’s a win-win for me
