This repository contains the source of the Tampermonkey extension up to version 2.9. All newer versions are distributed under a proprietary license.

Tampermonkey is the most popular userscript manager for Google Chrome.


  • manage and edit all your userscripts
  • enable and disable your scripts with 2 clicks
  • easily sync you scripts between different Chrome instances
  • search scripts from userscripts.org by URL (with TamperFire enabled)

Beneath of other tags, functions and features the following ones are supported:

  • full unsafeWindow access
  • all GM_* functions including (GM_registerMenuCommand, GM_getResourceText, GM_getResourceURL, GM_notification)
  • a lot of tags supported by Greasemonkey and Scriptish (like @resource, @require, ...)

For a full overview please take a look at the FAQ or just install TM. ;)

Google Chrome or Chromium 17 or higher


  • install Google Chrome or Chromium
  • install Cygwin when using Windows
  • open a konsole/terminal, and type:

cd svn checkout http://tampermonkey.googlecode.com/svn/trunk/ tampermonkey-read-only cd tampermonkey-read-only ln -s build_sys/mkcrxfolder.sh . ./mkcrxfolder.sh -e0

Depending on your installed browser and OS (I hope this makes the overall scheme clear ;)

chrome.exe --pack-extension=rel/ chromium.exe --pack-extension=rel/

coogle-chrome --pack-extension=rel/ chromium-browser --pack-extension=rel/

ls -la now shows two new files:

-rw-r--r-- 1 user user 305170 Aug 29 09:09 rel.crx -rw-r--r-- 1 user user 916 Aug 29 09:09 rel.pem

rel.crx is the Chrome extension, rel.pem the key to create another Tampermonkey extension file with the same extension ID

You can install rel.crx by drag'n'drop or (depending on your OS)

chrome.exe rel.crx chromium.exe rel.crx

coogle-chrome rel.crx chromium-browser rel.crx
