Does clearing the cache on a Firestick delete anything important?

No. The cache holds temporary files such as images and downloaded guide data, which the app rebuilds. Your login and settings stay. Clearing data is different: it resets the app completely.

Can I clear the cache for all apps at once?

Yes. In Settings > Applications > Manage Installed Applications, Amazon’s menu includes Clear all Application Caches.

How often should I clear the cache on a Firestick?

Only when an app misbehaves or storage is running low. Clearing it regularly for no reason just makes apps rebuild their files, so they start more slowly for a while.

Why can’t I uninstall some apps?

Preinstalled system apps generally can’t be removed. For apps you installed yourself, Uninstall is in Manage Installed Applications.

Clear Cache and Delete Apps on a Firestick

Clear the cache and delete apps on a Fire TV Stick

Clearing the cache is the quickest fix for an app that has become slow, freezes or misbehaves, and it frees space without logging you out. Clearing data goes further and resets the app. Here’s how to do both on a Fire TV Stick, and how to delete apps you no longer use.

Cache, data or uninstall: which one?

Action	What it removes	Your login	Use it when
Clear cache	Temporary files: images, thumbnails, some guide data	Kept	An app is slow, freezes or shows old information
Clear data	Everything the app has stored, including settings	Removed: you sign in again	Clearing the cache didn’t help, or the app won’t start
Uninstall	The app and all its data	Removed	You don’t use the app, or you’re reinstalling a fresh copy

Before clearing data in an IPTV player, note your login: server address, username and password, or your M3U link. You’ll need to enter it again.

Clear the cache for one app

Open SettingsApplicationsManage Installed Applications.
Select the app.
Select Clear Cache.
Open the app again. The first start can take a little longer while it rebuilds its files.

Clear every app’s cache at once

Open SettingsApplicationsManage Installed Applications.
Select Clear all Application Caches, then Confirm.

This is the quickest way to free space when the stick warns that storage is low. For more ways to free space, see Fire TV storage full.

Clear an app’s data

Open SettingsApplicationsManage Installed Applications.
Select the app, then Clear Cache, then Clear Data.
Open the app and set it up again, including your login.

Delete (uninstall) an app

Open SettingsApplicationsManage Installed Applications.
Select the app you want to remove.
Select Uninstall and follow the on-screen steps.

Good candidates to remove: players you tried and don’t use, apps from unknown developers, and installer files left behind by Downloader. Downloader can delete its own downloaded files; see the Downloader app.

When clearing doesn’t fix it

The app still freezes: restart the stick by holding Select and Play/Pause for about five seconds, then try again. See Firestick not working.
Video buffers: the cache is rarely the cause. See Firestick buffering.
An app won’t install afterwards: see app not installed. Amazon also blocks some apps outright; see blocked apps on Fire TV.
