I've got two actually. FireFox and Brave.

As of now, Firefox Developer browser. Works well tbh, I will be using it for a long time probably.

I use Firefox Developer and Brave

Oh and DuckDuckGo on my phone

I actually use Brave on my phone for free-AD block on mobile. But yea Firefox dev is pretty good tbh.

I started using Arc lately and really like it, but it's not approved for use at my company so I mainly use Chrome + Vimium. Opera was also pretty fun to play around with but Arc just feels like an actual next step now

Have you guys looked into vivaldi?

Vivaldi feels really similar to Opera (it was made by ex-Opera) with some more power user options. I enjoy it but I feel like the tab and space management of Arc flows better than Opera/Vivaldi

Yeah nothing about Vivaldi stuck out to me. But I also really like Firefox Developer.
