Blocking YouTube on a Fire tablet sounds simple — until the kid finds m.youtube.com in Silk, sideloads Chrome from an APK, or just opens YouTube on a phone that has no Amazon Kids profile at all. This guide walks the full fix: the tap-by-tap Amazon Kids setup, the Silk and sideloaded-browser cleanup, a router-level fallback for technical kids, and a cross-device layer for the next screen the child reaches for. Each section closes a specific gap, and the troubleshooting section covers what to do when YouTube sneaks back on through reinstalls, casting, or profile-switching. Pick the methods that match your household and stack them — one block is rarely enough. The Shorts feed needs its own lock — block YouTube Shorts for kids covers it.
A single block almost never holds, because YouTube reaches a Fire tablet through more than one door. Before you change settings, know which doors exist:
The YouTube app itself. Preinstalled on some Fire tablets or installable from the Amazon Appstore. This is the obvious target, but blocking it doesn't touch the web.
The mobile site in Silk. m.youtube.com loads in Amazon's Silk browser without the app — full video playback, no sign-in needed for most content.
A sideloaded browser. Chrome, Firefox, or Brave installed from an APK file bypasses Silk-level restrictions entirely, and a kid who learned to sideload once will do it again.
YouTube Kids. If it was ever installed, it's a separate app with its own icon and is not automatically covered when you block plain YouTube.
Casting from another device. A phone or laptop on the same Wi-Fi can cast YouTube to a nearby Fire TV or smart display the tablet is paired with, no Fire-tablet involvement at all.
Reinstalls after a block. If app installs aren't locked down, the child uninstalls the blocked YouTube app and reinstalls a fresh copy with no restriction history.
The rest of this guide closes each of these doors in turn. Use the comparison table in Method 4 to decide which combination matches your household.
Amazon Kids (the rebrand of FreeTime) is the cleanest path for a tablet that mostly belongs to one child. Here's the tap-by-tap:
Swipe down from the top of the home screen and tap Settings → Profiles & Family Library. Tap Add a Child Profile and set a parent PIN when prompted.
Enter the child's name, birthdate, and pick an avatar. Tap Add Profile.
Tap Amazon Kids on the home screen to enter the child profile, or tap your adult profile in the top-right and switch to the child.
From the parent dashboard (gear icon → Manage Your Content & Subscription → child name → Add Content), find the YouTube app in the list of installed apps and uncheck it. Save.
While you are in the child profile settings, set Daily Time Limits (a total cap per day) and Bedtime (a window when the tablet locks). If YouTube was the main time sink, this stops the kid from spending the freed time on a near-identical replacement.
Switch into the child profile and confirm the YouTube icon no longer appears on the home screen. If it does, force-close Amazon Kids and re-enter.
If the Fire tablet was never registered to Amazon Kids — for example, it shipped without a child profile or you bought it secondhand — you need to enroll it first. Open the Amazon Kids app on the tablet (download from the Appstore if it's missing), sign in with the Amazon account that owns the device, and create the child profile from scratch. The block list is per-profile, so the child must be using the kid profile when they pick up the tablet for any of this to apply.
This is the gap most guides skip. Even with the YouTube app removed from a child profile, m.youtube.com loads in Silk and plays video like the app does.
Inside Amazon Kids:
Open the parent dashboard, pick the child's profile, and go to Web Browsing.
Either turn web browsing off entirely (the strict option) or switch to allow specific websites and leave youtube.com, m.youtube.com, and youtu.be off the list.
If Silk must stay available for school sites, also add youtube.com, m.youtube.com, youtubekids.com, and youtu.be to the blocked list so they fail even when the allowlist is permissive.
Then close the sideload door:
Uninstall any non-Silk browser the child has access to — Chrome, Firefox, Brave, Opera, anything installed from an APK. In Settings → Apps & Notifications, tap the browser and choose Uninstall.
Disable Apps from Unknown Sources. Settings → Security & Privacy → Apps from Unknown Sources. Turn it off for every installed app source. Without this, a kid who finds a YouTube-website wrapper APK on the open web reopens the same door an hour after you closed it.
Verify. Switch into the child profile, open Silk, and try to load m.youtube.com. You should get a blocked page or no result. Repeat with youtu.be and youtubekids.com.
The most common failure here is leaving one sideloaded browser installed because you forgot it was there. Search the full app list, not just the home screen — sideloaded apps sometimes hide their launcher icon.
A router-level block is a safety net for technical kids who otherwise work around tablet-side settings. It applies to the Fire tablet whenever it is on your home Wi-Fi.
Open a browser on a device connected to your home Wi-Fi and visit your router's admin page — usually 192.168.1.1 or 192.168.0.1. Sign in with the admin password printed on the router.
Find Access Restrictions, Parental Controls, or URL Filter in the menu (the wording varies by brand).
Add the following domains to the block list:
youtube.com
m.youtube.com
youtu.be
youtubei.googleapis.com
youtubekids.com
Apply the block to the Fire tablet's MAC address specifically (find it under Settings → Device Options → About Fire Tablet → Wi-Fi MAC Address). This keeps your own adult devices unaffected.
Save and reboot the router if prompted.
Two honest limitations:
A cellular hotspot, a neighbor's open Wi-Fi, or a friend's network will bypass this block entirely. Router rules only apply to traffic that goes through your router.
Many modern routers can't fully enforce URL filters against HTTPS or DNS-over-HTTPS traffic. The block will work most of the time, but a determined kid using a privacy-focused browser may still slip through. Treat the router as defense in depth, not the primary control.
Amazon Kids does a clean job on the Fire tablet itself, but most kids in this guide's situation also carry an Android phone, an iPad, or borrow a parent's older device on the weekend. The YouTube rule that took twenty minutes to set up on the Fire tablet evaporates the moment the child switches screens. NexSpy is the layer that carries the same rule onto whichever screen the child reaches for next.
A per-app daily limit on YouTube does on a phone what Daily Time Limits do on the Fire tablet. Set the cap once — 30 minutes a day, an hour on weekends, zero during the school week, whatever matches the household rule. When the limit hits, the YouTube app locks automatically until the next day. The child doesn't have to remember; the device does it for them. The same control covers YouTube Kids, the YouTube website opened in any browser, and YouTube Music if you decide it counts toward the same budget.
Scheduled blocking handles the not-now cases without your phone buzzing every afternoon. Use:
School-time and bedtime schedules to make YouTube unreachable during class hours and after lights-out — the same windows you set on the Fire tablet, now mirrored on the phone.
Instant and scheduled App and Game Blocker to drop the hammer on YouTube the moment homework starts, and lift it automatically when the homework window ends.
Focus Mode for the hour of focused study where you want every distracting app off the table. Focus Mode locks every app on the device except the Phone app for emergencies, and the child cannot disable it on their own — only the parent can end it early.
The fastest way to make a YouTube block fail is to make it absolute with no relief valve. The NexSpy child request-permission flow lets the kid tap Request more time when YouTube is locked. You get a notification on the parent app, and you approve or deny in two taps. Most of the time the answer is no, but the kid learned that asking works once or twice — which is the difference between a rule that feels fair and a rule that motivates a sideload to win back fifteen minutes.
NexSpy runs the same rules across Android and iOS, so the family stays consistent whether the child's primary device this month is an iPad, a hand-me-down Pixel, or both. You set the YouTube cap, the school-time window, and the Focus Mode schedule once in the Parent Dashboard and they apply to every connected child device. The NexSpy Kids app has to be installed and connected on each child device for the rules to take effect; exact controls vary slightly by Android and iOS version and the permissions the OS grants.
NexSpy does not install on FireOS itself — that's where Amazon Kids does the work. Think of it as: Amazon Kids owns the Fire tablet, NexSpy owns the phone and iPad, and the rules read the same on both.
A few post-block failure modes show up over and over. Fix the matching one:
The kid reinstalled YouTube from the Appstore. Inside Amazon Kids → child profile → Set Restrictions, turn off the ability to install apps. New installs now require the parent PIN.
YouTube is loading in Silk again. You blocked the app but not the web. Go back to Method 2 and confirm the web allowlist excludes all four YouTube domains, not just youtube.com.
The kid is casting YouTube from a phone to a Fire TV or nearby smart display. The tablet block can't help — the source device is the phone. Apply a YouTube rule on the casting source (per-app limit on the phone, or sign out from the casting app).
Fire tablet was reset or de-registered from Amazon Kids. No blocks apply until the tablet is re-enrolled. Open the Amazon Kids app on the tablet, sign in, and recreate the child profile before checking any of the other steps.
Adult profile on the same tablet still has YouTube. Set a PIN on the adult profile (Settings → Parental Controls → Set a Parental Controls PIN). Without it, the child swipes from the Amazon Kids home screen to the adult profile and uses YouTube exactly as before.
Frequently asked questions
Can I block YouTube on a Fire tablet without Amazon Kids?
Yes, but not as cleanly. Without Amazon Kids you can uninstall the YouTube app, block youtube.com and m.youtube.com at the router, and disable Apps from Unknown Sources to stop sideload installs. The result is messier and easier to undo, but it does work for an unmanaged tablet.
Does blocking the YouTube app also block YouTube Kids?
No. YouTube Kids is a separate app with its own icon and Appstore listing. If it's installed, block it the same way you blocked YouTube — remove it from the child profile's approved content list, and add youtubekids.com to your web block list.
Can my child uninstall the parental control after I set it?
Not Amazon Kids — exiting the kid profile requires the parent PIN. For third-party parental control apps like NexSpy, the child cannot disable the rules or uninstall the kid-side app without the parent's account; only the parent can lift a block or end Focus Mode early.
What if I only want YouTube blocked during school hours, not all day?
On the Fire tablet, set narrow Daily Time Limits and a Bedtime that covers the school window. On a companion phone or iPad, use the NexSpy school-time schedule and scheduled App and Game Blocker so YouTube unlocks automatically outside the blocked hours.
Will a router block stop YouTube when the tablet is on cellular or a friend's Wi-Fi?
No. Router rules only apply to traffic going through your router. A hotspot or a different Wi-Fi network bypasses the router block entirely. That's the reason to combine router blocking with on-device controls (Amazon Kids on the Fire tablet, NexSpy on the phone).
