How to Restore Green HTTPS Icon in Firefox 70

One of the changes introduced in Firefox 70 is the gray HTTPS lock icon which replaced the green icon used in previous browser versions. If you are not happy with this change, you can restore the green lock icon. There is a hidden option for that.


The reason behind this change is that most web sites these days use the secure protocol with a certificate, HTTPS. So the green icon adds unnecessary distraction and doesn't play its previously important role, as per Mozilla research.

Mozilla is not the only company that invent changes like this. Earlier, Google has removed the 'Secure' text from the address bar of the Chrome browser. The change had been implemented in Chrome 69 for the same reason.

If you are not happy with this change, e.g. you just like the appearance the browser had with the green lock icon, it can be restored, at least in version 70 of Mozilla Firefox. Here's how it can be done.

To Enable Green HTTPS Icon in Firefox 70,

  1. Open Firefox.
  2. In a new tab, type about:config in the address bar.
  3. Click I accept the risk.Firefox About:config Warning
  4. In the search box, type security.secure_connection_icon_color_gray.Firefox Connection Icon Color Gray
  5. Set the parameter security.secure_connection_icon_color_gray to false by double-clicking on its row.Firefox 70 Enable Green Https Indicator

You are done!

Firefox 70 is yet another release of the Quantum engine-powered browser. Since 2017, Firefox has the Quantum engine which comes with a refined user interface, codenamed "Photon". The browser doesn't include support for XUL-based add-ons any more, so all of the classic add-ons are deprecated and incompatible. See

Thanks to the changes made to the engine and the UI, the browser is amazingly fast. The user interface of Firefox became more responsive and it also starts up noticeably faster. The engine renders web pages much faster than it ever did in the Gecko era.

Version 70 of Mozilla Firefox comes with a new icon, new privacy and safety features, adds better system dark theme support, and more.

  1. Thanks.
    Didn’t even know that they changed it. What’s worse is that I use a userChrome.css file to change the colors of the url bar text, causing the grey “HTTPS icon” to show in a bright red color.
