[BUG] Tampermonkey shows “Developer mode required” even when developer mode is already enabled (missing “Allow user scripts” permission)

[putridp]

On a fresh installation of Tampermonkey, the dashboard displays the banner:

“Developer mode is required. Please enable developer mode in chrome://extensions.”

However, enabling Chrome’s Developer Mode does not resolve the warning.
The actual missing permission is Chrome’s “Allow user scripts” toggle under the Tampermonkey extension entry — but Tampermonkey does not mention this at all.

This occurs consistently on first install and also when Tampermonkey is installed via Chrome Sync on another device.

Steps to Reproduce

Install Tampermonkey in a fresh Chrome profile OR allow Chrome Sync to auto-install it on a second device.
Open the Tampermonkey Dashboard.
A banner appears:
“Developer mode is required. Please enable developer mode in chrome://extensions.”
Go to chrome://extensions and enable Developer Mode.
Return to Tampermonkey — the warning remains.
Only after navigating to the Tampermonkey extension entry and enabling “Allow user scripts” does the warning disappear and scripts start injecting.

Expected Behavior

Tampermonkey should:
Detect when “Allow user scripts” is disabled,
Inform the user that this permission is required, or
Update the banner to mention the missing permission explicitly.

Actual Behavior
Tampermonkey shows a misleading banner about Chrome Developer Mode, which is already enabled.
It never mentions the crucial “Allow user scripts” permission.
As a result, users believe Developer Mode isn't working and think Tampermonkey is broken.
User scripts silently fail to inject until the user discovers this toggle manually.

Impact

Users cannot run any user scripts.
The message causes confusion because the wrong setting is referenced.
This affects every fresh install and machines receiving Tampermonkey via Chrome Sync.

Suggested Fix

Amend the banner to:
“Please enable Chrome’s ‘Allow user scripts’ permission for Tampermonkey in chrome://extensions.”
Or auto-detect and show a more specific error when that permission is disabled.

Environment

Chrome version: Version 142.0.7444.175 (Official Build) (64-bit)
OS: Windonws11 and OS X
Tampermonkey version: 5.4.1
Installed normally or via Chrome Sync: Both

Should be fixed at 5.5.6232 (crx)

Chrome/Edge users, please download the crx file linked above and drag and drop it to the extensions page chrome://extensions or wait for the Chrome Web Store review being done.

For a quick fix please export your settings and scripts as zip or (JSON) file at the "Utilities" tab and import it back at the fixed BETA version.

It doesn't work for me on Kubuntu 25.10
Brave 1.84.141 (Official Build) (64-bit)
Chromium: 142.0.7444.176

Edit: also tested on Windows.

Debería arreglarse en 5.5.6232 ( crx )

Usuarios de Chrome/Edge, descarguen el archivo crx vinculado arriba y arrástrenlo y suéltenlo en la página de extensiones chrome://extensionso esperen a que se realice la revisión de Chrome Web Store.

Para una solución rápida, exporte sus configuraciones y scripts como archivo zip o (JSON) en la pestaña "Utilidades" e impórtelos nuevamente a la versión BETA corregida.

Muchas gracias funcionó. Argentina.

Is this CRX certified?

[derjanb]

Yes, it's signed by the Chrome Web Store.

The bug continues in:
Brave is updated
Brave 1.85.118 (Official Build) (64-bit)
Chromium: 143.0.7499.169
With Tampermonkey Beta 5.5.6232 from the official store.

What exaclty continues? 5.5.6232 should warn about the "Allow user scripts" option being disabled. Is this correct?

You have developer mode enabled and yet tampermonkey is still telling you to enable user scripts.
