Debugging Firefox on iOS can be done using Safari’s Web Inspector. Here are the steps to get started:
Enable “Web Inspector” on your iOS device by going to “Settings” > “Safari” > “Advanced” and turning on “Web Inspector.”
Connect your iOS device to your Mac using a USB cable.
Open Firefox on your iOS device and navigate to the website you want to debug.
On your Mac, open Safari and go to “Preferences” > “Advanced” and check “Show Develop menu in menu bar.”
From the “Develop” menu in Safari, select your iOS device and choose the website you want to debug.
Note that not all features of Firefox may be available for debugging in Safari’s Web Inspector, and some debugging tasks may require additional tools or resources.
