Thanks, I appreciate your input!
Yes, I did try Mullvad for a short period of time right after the announcement of its release. I posted also about it here.
Mullvad Browser being TOR (without Onion routing) it comes tweaked for privacy out of the box so in that respect it is a worthy Firefox’ alternative. I do still have it in my system. I guess now its next release will based on FF 115 which is the new base for ESR.
I knew of Floorp as well but only curios to visit their site and not much more.
However, Pulse Browser was totally new to me. I will definitely keep an eye on it.
It is related to the topic the reason of it’s coming to be was concern for privacy that I think many of us share. Thanks again for pointing out these options!
