So, you want to enable or disable JavaScript on Firefox on your phone; there's just one thing...
Firefox on mobile devices (phones and tablets) no longer gives you the option to enable (or disable) JavaScript. As such, we can't give you a guide helping you to change this setting.
So many websites these days are reliant on JavaScript to work at all, it seems the Mozilla team have taken the stance that allowing users to disable JavaScript causes more problems than it solves; and so this setting can't be changed any more.
Here are some guides for other web browsers like Safari or Chrome.
What is JavaScript and what does it do?
Turn on/activate JavaScript.
What happens if you don't have JavaScript?
How do web developers use JavaScript?
What are some of the concerns with JavaScript and security?
Does my browser already have JavaScript or do I have to install it?
Does JavaScript go out of date?
What is the percentage of websites that use JavaScript?
What are the reasons someone would disable JavaScript in their browser?
What restrictions are there that keep me safe?
You can choose to disable JavaScript
Are they the same thing?
