Disable developer mode extensions pop up in Chrome

Question

Since the latest release of chrome  34 0 1847 116  last week  I have been receiving the     Disable developer mode extensions  when running automated tests using watir-webdriver    This seems to be the offensive extension but it doesn t make sense to me that this is a potentially hazardous extension given its used by the chromedriver   Anyone that has found a fix for this  as i am unable to roll back to the previous version or find an installer for an older version to roll back to and this is playing havoc with my tests

As of May 2015 Chrome beta dev canary on Windows  see lines 75-78  always display this warning    I ve just patched chrome dll  dev channel  32-bit  using hiew32 demo version  run it  switch to hex view  Enter key   search for ExtensionDeveloperModeWarning  F7  then press F6 to find the referring code  go to nearby INC EAX line  which is followed by RETN  press F3 to edit  type 90 instead of 40  which will be rendered as NOP  no-op   save  F9    Simplified method found by  Gsx  which also works for 64-bit Chrome dev    run hiew32 demo  in admin mode  and open Chrome dll switch to hex view  Enter key  search for ExtensionDeveloperModeWarning  F7  press F3 to edit and replace the first letter  E  with any other character save  F9     patch BAT script   Of course this will last only until the next update so whoever needs it frequently might write an auto-patcher or a launcher that patches the dll in memory

I was suffering from the same problem  and I tried the following    Pack the unpacked extension Turn off Developer Mode Drag and drop the  crx file from the packed extension Close Chrome  and then open it again    A few things to note    The  pem file should be kept with the  crx Don t put the  crx and the  pem in the folder of the unpacked extension    When I reopened Chrome  I got a popup that told me about the new packed extension  so I rebooted Chrome to see if it would do it again  and it did not   I hope this solution worked

This question is enormously old but is still the top result on google when you search for ways to try to disable this popup message as an extension developer who hasn t added their extension to the chrome store  doesn t have access to group policies due to their OS  and is not using the chrome dev build  There is currently no official solution in this circumstance so I ll post a somewhat  hacky  one here    This method has us immediately create a new window and close the old one  The popup window is associated with the original window so in normal use cases the popup never appears since that window gets closed   The simplest solution here is we create a new window  and we close all windows that are not the window we just created in the callback   chrome windows create       type   normal       focused  true      state   maximized     function window        chrome windows getAll function windows            for  var i   0  i  lt  windows length  i                  if  windows i  id    window id                    chrome windows remove windows i  id                                         Additionally we can detect how this extension is installed and only run this code if it is a development install  although probably best to completely remove altogether from release code   First we create the callback function for a chrome management getSelf call which allows us to check the extension s install type  which is basically just wrapping the code above in an if statement   function suppress dev warning info        if  info installType     development             chrome windows create               type   normal               focused  true              state   maximized             function window                chrome windows getAll function windows                    for  var i   0  i  lt  windows length  i                          if  windows i  id    window id                            chrome windows remove windows i  id                                                                                 next we call chrome management getSelf with the callback we made   chrome management getSelf suppress dev warning     This method has some caveats  namely we are assuming a persistent background page which means the code runs only once when chrome is first opened  A second issue is that if we reload refresh the extension from the chrome   extensions page  it will close all windows that are currently open and in my experience sometimes display the warning anyways  This special case can be avoided by checking if any tabs are open to  chrome   extensions  and not executing if they are

The official way to disable the popup is this    Pack your extension  go to chrome   extensions  check Developer mode and click Pack extension Install the extension by dragging and dropping the  crx file into the chrome   extensions page    You ll get an  Unsupported extensions disabled  popup if you try restarting Chrome at this point   Then for Windows 7 or Windows 8    Download Chrome group policy templates here Copy  zip  windows admx chrome admx to c  windows policydefinitions    Copy  zip  windows admx  yourlanguage  chrome adml to c  windows policydefinitions  yourlanguage  chrome adml  not c  windows  yourlanguage   In Chrome  go to the Extensions page  chrome   extensions Check Developer Mode Scroll down the list of disabled extensions and note the ID s  of the extensions you want to enable  Click Start   Run  type gpedit msc and hit enter  Click User Configuration   Administrative Templates   Google Chrome   Extensions Double click Configure extension installation whitelist policy Select Enabled  and click Show In the list  enter the ID s  of the extensions you noted in Step 7 Click OK and restart Chrome    That s it   EDIT  As of July 2018  this approach no longer works  it seems Google has stopped honouring the  whitelist    EDIT 2  As of December 2018  this approach works in Chrome Version 69 0 3497 100  Official Build   64-bit     Temporarily enable Developer mode in chrome   extensions Uninstall the extension that causes the popup using the Load unpacked  Click on Pack extension  and find and select the folder containing the extension files  Don t enter the private key file if you don t have it  Click Pack extension  A  crx and  pem file will be created near the root directory of the extension  Install the extension using the  crx file and keep the  pem file safe  Copy the  crx installed extension ID to the whitelist and restart Chrome    The popup should be gone

Unfortunately I cant automate setting it to developer mode because of restrictions in width using the browser in iphone mode  I have found a dangerous workaround for now  install the dev channel version of chrome  It does not have the warning message  but im sure it will cause me more problems in the long run when problems are introduced  Still will hopefully give me a few days to find a workaround

Based on Antony Hatchkins s answer  The official way to disable the popup seems to be like this   Pack your extension  chrome   extensions   tick at  Developer mode   hit  Pack extension      and install it via drag-and-dropping the  crx file into the chrome   extensions page   Since the extension is not from Chrome Web Store  it will be disabled by default     Then for Windows   In Chrome  go to the Extensions page  chrome   extensions  Check the Developer Mode checkbox at the top Scroll down the list of disabled extensions and note the ID s  of the extensions you want to enable  LogMeIn  for example  is ID  nmgnihglilniboicepgjclfiageofdfj Click Start  gt  Run  and type regedit  lt ENTER gt  Under key HKLM Software Policies Google Chrome ExtensionInstallWhitelist  create it if not exists   create a new string for each extension you want to enable with sequential names  indices   e g  1  2      Enter the extension ID s  as string values in any order  For example  there is a string with name 1 and value nmgnihglilniboicepgjclfiageofdfj Restart Chrome  That s it  Note  When you update a whitelisted extension  you do not have to follow the same steps since the ID of the extension will not change

I found something that will load user-packed extensions and works beautifully   You ll still have to pack it in details for the problem extension  but after that you can turn off developer mode and load the packed CRX through this  You don t have to deal with signing it or anything   https   chrome google com webstore detail crosspilot migomhggnppjdijnfkiimcpjgnhmnale hl en  Note  I m not from their team  I ve just been looking for an elegant solution for this for years
