Sticky Menu functionality in Dashboard

There used to be an extension called Ontraport Power User for both Chrome and Firefox that added a menu to everypage so a user could access all parts to the app from any page, including landing page editor, etc. 

The extension has finally after 8 years been discontinued and the old workaround of forcing Chrome to allow the extension just stopped working. I am FREAKING out. Everything is taking literally twice as long..
