PM75233: Trying to install the 'Enable Useragent Switching' extension in the mobile browser simulator results in an error in Chrome

Rational Application Developer for WebSphere Software 8.5.1

APAR status

• Closed as program error.

Error description

• Abstract:
  
  Attempts to install the extension after selecting 'Enable
  Useragent Switching' in the mobile browser simulator results in
  an error from Chrome.
  
  Problem:
  
  When you enter the URL for the mobile browser simulator page
  into Chrome, and then select 'Enable Useragent Switching', you
  get a popup that tells you to install an extension.  After
  selecting the URL, Chrome pops up a message stating you can only
  install Extensions from their Chrome store.
  
  Local fix:
  
  Because of a change in how Chrome handles extensions, you must
  now manually install the extension.  The steps to do this are:
  
  1) Paste your URL into Chrome.
  2) From the Chrome browser, select the 'Customize and control
  Google Chrome' icon in the top right corner (it's a square with
  3 horizontal lines on it).
  3) From the  'Customize and control Google Chrome' menu select
  Tools ? Extensions.  This will open a new tab.
  4) Again from the  'Customize and control Google Chrome' menu
  select Downloads.  This will again open a new tab.
  5) From the Downloads tab select the 'Open downloads folder'
  link on the right side.  This will open your File Explorer.
  6) From your File Explorer, drag/drop the
  'mbsuseragent@rational.ibm.com.crx' file to the main section of
  the Extensions tab (ie.  some where in the middle of the page.
  If you drag/drop to the tab itself you will still be told you
  have to use the Chrome store).
  7) You can then 'Add' the extension from the pop-up.

  After the 8.5 was released, Google made a change to the
  policy for Chrome extensions. Extensions could be
  automatically installed only if they are in the Chrome Web
  Store. Since the user agent switching Chrome extension is
  not in the Chrome Web Store, an error message is returned by
  Chrome.
  

Problem conclusion

• In 8.5.1 the user interface is changed to provide
  instructions to the user on how to manually install the
  Mobile Browser Simulator user agent switching extension. For
  8.5, users should follow these same steps, which are
  detailed in the APAR Error Description.
  
  The fix for this APAR is included in Rational Application
  Developer v8.5.1.
