How do I disable Google Chrome extension autoupdate?
You can do this by editing the extension's manifest.json file:
On Windows: C:\Users\<USERNAME>\AppData\Local\Google\Chrome\User Data\Default\Extensions\<EXTENSION-ID>\<VERSION>\manifest.json (find out the extension's ID by enabling Developer Mode in the extension settings page)
On MacOS: Open /Users/USERNAME/Library/Application Support/Google/Chrome/Default/Extensions/EXTENSION-ID/VERSION/manifest.json in a text editor.
On Ubuntu for Chromium: ${HOME}/.config/chromium/Default/Preferences
In this file, set the "update_url" property to something invalid like "https://localhost" for example. For the given url, it makes auto-updating that extension as simply impossible.

Until 2017 ( https://issues.chromium.org/issues/40471118 ), you could also disable all Google Chrome extension updates:
For any OS: Just type chrome://plugins/ at address bar and turn Google Update plugin off. Source: How to disable Google Chrome auto update?
For Windows OS: Set Registry values:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Update]
"AutoUpdateCheckPeriodMinutes"=dword:00000000
"UpdateDefault"=dword:00000000
