When Mozilla launched a re-designed version of Firefox for Android a few years back, it only came with support for a few add-ons – just for the sake of compatibility. Fast forward to present day and the restoration of full add-on support is not yet complete. The good news, however, is that it’s possible to install any add-on in Firefox for Android via a workaround. We show you how.

When accessing the add-on website in Firefox on PC, you’ll be taken to the list of recommended extensions. Here you’ll notice that there’s no option to install any of the desktop-compatible add-ons on your Android device.

Note: All collections are public and can be viewed by anyone.

  1. Take note of the collection name and eight-digit number or ID shown in the address bar of the collection URL page. For example, this collection’s name is “Favorites,” and the eight-digit unique ID is “13590312.”

ClearURLs automatically removes tracking elements from the URL and helps protect your privacy. The extension blocks hyperlink auditing (used by search engines like Google to track the links you clicked), as well as some common ad domains, and more. Now when you share a link to the Amazon product page with a friend, they’ll see them without any clutter.

Frequently Asked Questions

How many add-on collections does Firefox for Android support?

As of now, you can only import only one collection into Firefox for Android per session. On the bright side, you can create as many collections as you wish via the Firefox add-ons website. When you need an add-on from a different collection, just import that one into Firefox for Android.

Why doesn't Firefox for Android support all add-ons like on desktop?

It’s because of the nature of the Android ecosystem, limitations in APIs, lack of proper windowing environment, usability on smaller screens, and more. Despite this, there are still plenty of ways you can multi-task on Android and stay productive.

You can check out the detailed list of the WebExtensions APIs support for Android in the browser support for Javascript APIs page. For every feature implementation, you can track its status in different browsers and the version it supports.
