@obsolescentsapien @nixCraft I use Firefox since many years.
But I have to admit that it's slightly slower than Chromium (I don't know if it is Firefox's fault or if it is because people develop websites optimized for Chromium only now)
Firefox takes time to implement new CSS features compared to Chromium browsers.
Some criticaly needed apps in the browser only run on Chromium browser (MS Teams etc.).
So ❤ to Firefox, it's still my daily driver, but I need a Vivaldi install on the side also.
