How to Install Ultra Max Stremio Addon (Catalog Collections)
Step-by-step guide to installing the Ultra Max addon on Stremio for Firestick. Covers all catalog options, cross-device sync, and how to fix common manifest errors.
I’ve been running Stremio on my Firestick 4K Max for a while now, and the addon ecosystem is where it really earns its keep. Ultra Max is one of those addons that sounds flashy but actually delivers — it pulls in a massive catalog of movies and TV shows, and the setup is less complicated than it looks once you know the trick.
That trick, by the way, is Stremio’s cross-device sync. You don’t install Ultra Max on your Firestick directly — you install it on your phone or browser, and your Firestick picks it up automatically. I’ll walk through exactly how that works.
To install Ultra Max on Stremio: go to max-streams.gleeze.com, choose your catalog option (Quick Install is the fastest for most people), copy the addon URL, and paste it into Stremio’s “Add Addon” field on any device. Once logged into the same Stremio account, it syncs automatically to your Firestick. The whole process takes about 2 minutes.
What You Need Before You Start
Before we get into the steps, make sure you have the basics covered:
- Stremio installed on your Firestick (here’s the full setup guide if you need it)
- A Stremio account — signed in on both your Firestick and whatever secondary device you’ll use for the install (phone, tablet, or browser)
- Real-Debrid (optional but highly recommended — more on this below)
What Catalog Options Does Ultra Max Offer?
When you visit the Ultra Max website, you’ll get four pre-configured catalog options. Here’s the breakdown:
| Option | What It Includes | Best For |
|---|---|---|
| Quick Install (No Anime or Bollywood) | Movies and TV shows, US/UK focused | Most users — clean and fast |
| All Content | Everything including Anime and Bollywood | International content fans |
| Custom | You choose what categories to include | Power users who want control |
| Live TV (Experimental) | Live channel streams | Cord-cutters, but expect instability |
I went with Quick Install for testing. It loaded cleanly without the extra catalog bloat that can slow down Stremio’s home screen.
How to Install Ultra Max on Stremio (Firestick)
The key thing to understand: you install Ultra Max on a secondary device, and it syncs to your Firestick automatically via your Stremio account. You can also install it directly through the Stremio app on your Firestick if you prefer — both methods work.
Install Ultra Max on Stremio
6 stepsVisit the Ultra Max Website
On your phone, tablet, or PC, open a browser and go to max-streams.gleeze.com. You’ll see the four catalog options listed on the page.
Choose Your Catalog
Select the option that fits your needs. For most Firestick users, Quick Install (No Anime or Bollywood) is the right call — it’s faster to load and cuts out catalog noise you probably don’t need.
Copy the Addon URL
After selecting your catalog option, the page will generate an addon URL. Copy it — you’ll paste this into Stremio in the next step.
Open Stremio and Go to Addons
Open the Stremio app on your phone or in your browser. Navigate to the Addons section (the puzzle piece icon). Look for the “Add Addon” button or input field — it’s usually at the top of the addon search screen.
Paste the URL and Install
Paste the Ultra Max URL you copied into the field and hit Install. Stremio will fetch the addon manifest and confirm the installation. If it succeeds, you’ll see Ultra Max listed under your installed addons.
Open Stremio on Your Firestick
Open the Stremio app on your Firestick and make sure you’re logged into the same account. The Ultra Max addon should already be synced — you’ll see the new catalogs appear on the Stremio home screen within a few seconds. If nothing shows up immediately, back out and reopen a title to trigger a refresh.

→Troubleshooting: Manifest Errors
The most common issue with Ultra Max is a manifest retrieval error — you’ll see something like:
“Failed to get addon manifest from https://max-streams.gleeze.com/manifest.json”
This usually means one of three things:
- The addon URL is outdated — go back to max-streams.gleeze.com and generate a fresh URL, then reinstall.
- The server is temporarily down — wait 10–15 minutes and try again.
- Your Stremio version is outdated — update Stremio to the latest version before retrying. Our guide to updating Stremio on Firestick walks through this if needed.
Ultra Max: Pros and Cons
Ultra Max
- Four pre-configured catalog options for different preferences
- Cross-device sync means one install covers your Firestick automatically
- Live TV option included (experimental)
- Free to use — no subscription required
✓ Pros
- Simple URL-based install — no sideloading required
- Four catalog configurations let you control what appears on your home screen
- Syncs automatically to Firestick via your Stremio account
- Works alongside Real-Debrid for better link quality

✕ Cons

Pair Ultra Max With Real-Debrid for Better Results
Ultra Max on its own will surface links — but many of them will be slow, low-quality, or dead. Add Real-Debrid to your Stremio setup and the difference is immediately noticeable: faster loads, more 1080p and 4K options, and fewer broken streams.
