Zen Browser (FF) on Win and Firefox on iOS (for sync) works well for me. Edge for all M365 related stuff. Still use Chrome for web dev. Not sure what to move on in that regard...
I use FF for 99% of dev, open Chrome maybe once a quarter. It’s a better browser.
Basically, you can press "ctrl S" for save, straight from the dev console. In FF, you have to manually designate the save location each time. It may seem like a small thing, but it's an entirely different workflow.
For frameworks that don't use plain stylesheets, it may not be useful.
