On Firefox mobile, blocking a website is a little different. You may download a free browser plugin if you’re using an Android phone.

It works similarly to Site Blocker. Instead, you may use the built-in Screen Time feature if you’re on iOS or iPad OS. Please keep in mind that this affects all browsers, not just Firefox. Be aware that it will apply to any device that uses your iCloud account, so be cautious. Here’s how you can put it to use:
