Update 2016  seems to be working again   Update August 2014  No longer works as of recent Chrome versions     Yeah  the new state of affairs sucks  Fortunately it s not so hard as the other answers imply    Browse in Chrome to chrome   extensions  Drag the  user js file into that page    Voila  You can also drag files from the downloads footer bar to the extensions tab   Chrome will automatically create a manifest json file in the extensions directory that Brock documented    lt 3 Freedom

The best thing to do is to install the Tampermonkey extension   This will allow you to easily install Greasemonkey scripts  and to easily manage them   Also it makes it easier to install userscripts directly from sites like OpenUserJS  MonkeyGuts  etc   Finally  it unlocks most all of the GM functionality that you don t get by installing a GM script directly with Chrome   That is  more of what GM on Firefox can do  is available with Tampermonkey     But  if you really want to install a GM script directly  it s easy a right pain on Chrome these days     Chrome After about August  2014   You can still drag a file to the extensions page and it will work    Until you restart Chrome   Then it will be permanently disabled   See Continuing to  protect  Chrome users from malicious extensions for more information   Again  Tampermonkey is the smart way to go   Or switch browsers altogether to Opera or Firefox    Chrome 21     Chrome is changing the way extensions are installed  Userscripts are pared-down extensions on Chrome but  Starting in Chrome 21  link-click behavior is disabled for userscripts  To install a user script  drag the    user js  file into the Extensions page  chrome   extensions in the address input    Older Chrome versions   Merely drag your    user js  files into any Chrome window   Or click on any Greasemonkey script-link   You ll get an installation warning    Click Continue    You ll get a confirmation dialog    Click Add     Notes    Scripts installed this way have limitations compared to a Greasemonkey  Firefox  script or a Tampermonkey script   See Cross-browser user-scripting  Chrome section      Controlling the Script and name   By default  Chrome installs scripts in the Extensions folder1  full of cryptic names and version numbers   And  if you try to manually add a script under this folder tree  it will be wiped the next time Chrome restarts   To control the directories and filenames to something more meaningful  you can    Create a directory that s convenient to you  and not where Chrome normally looks for extensions   For example  Create  C  MyChromeScripts   For each script create its own subdirectory   For example  HelloWorld  In that subdirectory  create or copy the script file   For example  Save this question s code as  HelloWorld user js  You must also create a manifest file in that subdirectory  it must be named  manifest json   For our example  it should contain          manifest version   2       content scripts                exclude globs                     include globs                        js                    HelloWorld user js              matches                 https   stackoverflow com                                      https   stackoverflow com                                            run at    document end                converted from user script   true       description     My first sensibly named script         name            Hello World        version         1      The manifest json file is automatically generated from the meta-block by Chrome  when an user script is installed  The values of  include and  exclude meta-rules are stored in include globs and exclude globs   match  recommended  is stored in the matches list   converted from user script   true is required if you want to use any of the supported GM   methods  Now  in Chrome s Extension manager  URL   chrome   extensions    Expand  Developer mode   Click the Load unpacked extension    button  For the folder  paste in the folder for your script  In this example it is  C  MyChromeScripts HelloWorld  Your script is now installed  and operational  If you make any changes to the script source  hit the Reload link for them to take effect              1 The folder defaults to    Windows XP    Chrome     AppData     Local Settings Application Data Google Chrome User Data Default Extensions    Chromium   AppData     Local Settings Application Data Chromium User Data Default Extensions   Windows Vista 7 8    Chrome     LocalAppData  Google Chrome User Data Default Extensions    Chromium   LocalAppData  Chromium User Data Default Extensions   Linux    Chrome       config google-chrome Default Extensions    Chromium     config chromium Default Extensions   Mac OS X    Chrome      Library Application Support Google Chrome Default Extensions    Chromium    Library Application Support Chromium Default Extensions    Although you can change it by running Chrome with the --user-data-dir  option
