How To Clear Cache On A Firestick

To clear cache on a Firestick: 1. From the home screen, open Settings (the gear icon at the far right). 2. Select Applications. 3. Select Manage Installed Applications. 4. Choose the app that is misbehaving — Netflix, Hulu, Crunchyroll, whatever. 5. Scroll down and select Clear cache. That is it — the app keeps you signed in, but its temporary junk files are gone. On newer Fire OS versions there is also a one-click Clear All App Caches option right on the Applications screen, which does every app at once. Below: the difference between clearing cache and clearing data (one signs you out, one does not), when clearing cache actually helps, and what to do when it is not enough.

Clear Cache vs. Clear Data: Know The Difference

Both buttons live on the same screen, and they do very different things:

• Clear cache deletes temporary files — thumbnails, partial downloads, leftover video segments. You stay signed in and lose nothing. This is the safe one, and the one to try first.
• Clear data resets the app to a factory-fresh install. It wipes your login, downloads, and in-app settings. Use it only when clearing the cache did not fix the problem — and be ready to sign back in afterward.

A good rule: cache first, restart the Firestick, and only reach for Clear data if the app is still broken.

The One-Click Option: Clear All App Caches

Amazon added a system-wide cache-clearing button to Fire TV in a software update that rolled out in late 2025. Go to Settings > Applications and look just below Manage Installed Applications for Clear All App Caches. One click empties the cache for every installed app — a genuine time-saver on a stick that has been accumulating junk for a year. If you do not see the option, your Firestick has not received the update yet: see how to update your Firestick, then check again.

When Clearing The Cache Actually Helps

• One app keeps crashing or freezing while others work fine — the classic sign of corrupted cache files in that app.
• Endless buffering on a fast connection. If a speed test looks healthy but one app stutters, stale cache is a prime suspect. (If it is Netflix acting up, our Netflix troubleshooting guide pairs well with this.)
• "Insufficient storage" warnings. Firesticks ship with as little as 8GB, and cache eats into it fast. Clearing caches can recover a surprising amount.
• General sluggishness — slow menus, apps taking ages to open. Cached bloat plus low free storage is usually the cause.

What it will not fix: network problems, account issues, or the "home is currently unavailable" error, which is its own beast with its own guide.

Free Up More Storage While You Are In There

1. Check what you are working with: Settings > My Fire TV > About > Storage shows how much space is left.
2. In Manage Installed Applications, uninstall apps you have not opened in months — each entry shows how much space it occupies.
3. Clear the cache on the big offenders. Streaming apps that get daily use (YouTube, Netflix, Hulu) grow the largest caches.

Restart After Clearing — It Matters

A restart lets Fire OS rebuild cleanly and finishes the job. Three ways to do it:

• Menu: Settings > My Fire TV > Restart.
• Remote shortcut: hold Select + Play/Pause together for about five seconds.
• Power cut: unplug the stick from power for 30 seconds. (Firesticks have no off switch — unplugging is a legitimate restart.)

Clearing Cache On Fire TV Cube And TVs With Fire TV Built In

The steps are identical across the whole Fire TV family — Firestick, Firestick 4K and 4K Max, Fire TV Cube, and televisions from Insignia, Toshiba, and Amazon's own Omni line that run Fire TV as their operating system. On all of them: Settings > Applications > Manage Installed Applications > [app] > Clear cache. The only practical difference is that built-in Fire TVs usually have more storage than an 8GB stick, so they take longer to fill up — but a misbehaving app benefits from a cache clear just the same. If your remote is being uncooperative, the free Fire TV app on your phone works as a remote and can navigate the same menus.

One more habit worth building: clear the cache before a big night of streaming rather than after something breaks mid-episode. It takes under a minute, and it is the single most effective piece of routine maintenance a Fire TV device gets. If an app still will not behave after a cache clear, a data clear, and a restart, uninstall and reinstall it — that replaces any corrupted files the cache buttons cannot touch.

FAQ

Will clearing the cache sign me out of my apps?

No. Clearing cache keeps every login intact. Clearing data is the one that signs you out.

How often should I clear my Firestick's cache?

There is no schedule to keep — do it when something misbehaves or storage runs low. Monthly is plenty for heavy streamers; the Clear All App Caches button makes it painless.

Does clearing the cache make a Firestick faster?

Often, yes — especially on older 8GB sticks where free storage is scarce. If yours is still slow after clearing caches, uninstalling unused apps and updating Fire OS are the next two moves, and a stick from 2018 or earlier may simply be at the end of its road.

Is clearing the cache the same as resetting the Firestick?

No. A factory reset (Settings > My Fire TV > Reset to Factory Defaults) wipes the whole device. Clearing cache only touches temporary files for the apps you choose.
