Things You Need Before Installing Kodi on Firestick & Fire TV

Before installing Kodi on Firestick or Fire TV, you’ll need 4 things:

• A stable internet connection with a minimum 15 Mbps speed.
• An active Amazon account.
• Sufficient storage (minimum 500 mb for installation).
• An Amazon Fire TV Stick, Fire TV Stick 4K, 4K Max, Lite, or Fire TV Cube, connected to your TV.

How to Install Kodi 21.3 on Firestick & Fire TV

Many users think installing Kodi on Firestick is complicated, but the process is quite simple. Since Kodi isn’t available in the Amazon App Store, you’ll need to sideload it using the Downloader app, enable developer options, and then install the official Kodi app on your Firestick or Fire TV.

Here are the steps for installing Kodi 21.3 on Firestick and Fire TV:

Step 1: Enable Apps From Unknown Sources on Firestick

Because Kodi is not in the Amazon App Store, you have to allow your Fire TV Stick to install apps from outside it. This is a one-time setting.

1. From the Firestick home screen, open Settings (gear icon in the top menu).
2. Select My Fire TV.
3. Choose Developer Options.
4. Click Install Unknown Apps or Apps from Unknown Sources.
5. Find Downloader in the list and toggle it ON.

Do not see Developer Options? Go to My Fire TV, then About, highlight your device name, and click it seven times in a row. Developer Options will appear after that.

You’ll see the message – “No Need, You’re Already a Developer”.

Step 2: Install the Downloader App

If you already have Downloader installed, skip to Step 3.

1. Press the Home button on your remote.
2. Open Find, then select the Search option (magnifying glass).
3. Type Downloader and select the orange icon by AFTVnews.
4. Click Download or Get.
5. Once installed, open Downloader and grant any permissions it requests.

Pro tip from testing: Open Downloader’s settings and enable JavaScript before continuing. Some download pages (including the Kodi mirror) will not load correctly without it.

Step 3: Download and Install Kodi 21.3 Omega on Firestick

This is the main install. The whole step takes around 2 to 3 minutes, depending on your internet.

1. Open Downloader and select the Home tab on the left.
2. Click the URL box at the top of the screen.
3. Type the official Kodi URL: kodi.tv/download/android and press Go.
4. The official Kodi download page will load on your Fire TV Stick.
5. Scroll to the Android section and select ARMV7A (32BIT). This is the correct build for every Fire TV Stick model in 2026.
6. The download will start. The Kodi 21.3 APK is around 93 MB and downloads in a few minutes (2.45-3.10).
7. When the download completes, Downloader will prompt you to install. Click Install in the bottom right corner.
8. The install runs automatically and takes about 25-35 seconds.
9. Click Done when the install confirmation appears.
10. Back in Downloader, click Delete twice to remove the leftover APK file and free up space. (This does not remove Kodi itself.)

That is the installation complete. Kodi is now on your Firestick.

So, what’s your take on this? Too complicated?! You can install it more quickly with a speedy net connection (my connection was a bit slow during the process!).

However, there’s a catch. You should use the official add-ons and a VPN to get seamless streaming. If you’re using Kodi on Firestick and Fire TV without a VPN in 2026, your ISP can see exactly what you’re accessing. But which VPN could be useful?
