How to Silence Chrome’s ‘Disable Developer‑Mode Extensions’ Warning with a Simple DLL Patch

Chrome users who install extensions manually (offline) frequently encounter a warning that says “Please disable extensions running in developer mode” each time the browser starts. The message appears because Chrome detects extensions that are not officially signed or distributed through the Chrome Web Store.

Various attempted fixes—editing the Windows registry, replacing DLL files, applying patch packages—are either ineffective or overly complex. After testing multiple approaches, a simple replacement of the version.dll file in the Chrome installation directory proved to work for the author’s Chrome 80.0.3987.122 (64‑bit) build.

Step‑by‑Step Patch Procedure

Download the version.dll patch file from the referenced source.

Locate Chrome’s installation folder. Right‑click the Chrome shortcut and choose “Open file location” to open the directory containing chrome.exe.

Copy the downloaded version.dll into this folder, ensuring it sits alongside chrome.exe.

Restart Chrome. The warning message should no longer appear.

Note that the fix was verified only on the author’s specific Chrome version; it may not work on newer or older releases. The author does not guarantee the safety or stability of the patch, and users should apply it at their own risk.
