ChromeGoogle has recently made changes to the way Chrome tackles extensions to announce possible harm to users through some of the developer mode functions. This has affected many of the well-known wide-used extensions, like Roboform, resulting in the following message every time you open the browser:

Chrome extensions warning developer mode

There is an easy workaround. See below.


The easiest fix is to download the developer version of Chrome here.


The Chromium blog explains :

Extensions are a great way to enhance the browsing experience; whether users want to quickly post to social networks or to stay up to date with their favorite sports teams. Many services bundle useful companion extensions, which causes Chrome to ask whether you want to install them (or not). However, bad actors have abused this mechanism, bypassing the prompt to silently install malicious extensions that override browser settings and alter the user experience in undesired ways, such as replacing the New Tab Page without approval. In fact, this is a leading cause of complaints from our Windows users.

Since these malicious extensions are not hosted on the Chrome Web Store, it’s difficult to limit the damage they can cause to our users. As part of our continuing security efforts, we’re announcing a stronger measure to protect Windows users: starting in January on the Windows stable and beta channels, we’ll require all extensions to be hosted in the Chrome Web Store. We’ll continue to support local extension installs during development as well as installs via Enterprise policy, and Chrome Apps will also continue to be supported normally.

If your extensions are currently hosted outside the Chrome Web Store you should migrate them as soon as possible. There will be no impact to your users, who will still be able to use your extension as if nothing changed. You could keep the extensions hidden from the Web Store listings if you like. And if you have a dedicated installation flow from your own website, you can make use of the existing inline installs feature.

Protecting our users is a key priority, and we believe this change will help those whose browser has been compromised by unwanted extensions. If you have questions, please get in touch with us on the Chromium extensions group.


Another workaround you  can try is to :

  1. Open Chrome browser.
  2. Select the options button in Chrome>Tools>Extensions>Developer Mode>Load Unpacked Extensions>
  3. When the browse folder window opens goto the directory that contains the plugin (example, Roboform: Computer>> Program Files>>Siber Systems>>AI RoboForm>>Chrome)


Will probably not take long for the serious companies to deal with this so you won’t need this workaround.

    “If your extensions are currently hosted outside the Chrome Web Store you should migrate them as soon as possible.” — Not for $5, thanks google.

    **SOLVED** Tried the above methods but did not work.
    I removed the EasyPass(roboform) extension from Chrome browser & closed it => reset EasyPass settings to default & set Chrome as default browser
    => started Chrome which initiated EasyPass install, restart Chrome again & no more annoying message, hope this helps someone else 🙂
