Has anyone found a particular web browser to be better for writing wix code?
You can use any of the Supported Browsers mentioned here however, in my opinion, Chrome is the best for debugging your code.
I think that Mozilla Firefox ( https://rocketfiles.com/windows/browsers/web-browsers/mozilla-firefox) is the best option to code online. It required less RAM if we compare it with Chrome and it works faster and more secure. But, in general, I think that choosign the broser for coding is just a personal choice. So, you ca easily wirte a code in your beloved browser.
