Why? I really enjoy the new edge chromium. It feels very smooth, is very fast and I have had no major problems.

I've tried chrome, but do not like where they are heading (removing AdBlock functionality, no privacy)

I've tried Firefox, but after years of chromium based browsers, it just felt off. No hard reason, I just didn't like it.

I tried numerous small browsers like Vivaldi and Brave, but they were not polished enough and started selling ads within my browser.

Edge does everything I want, supports Chrome plugins, feels modern.
