Favorites and bookmarklets in Microsoft Edge

I use Microsoft Edge as my primary browser since Windows 10 was released, and I am really satisfied with it. I don’t miss the plugins, but saving a bookmarklet was trickier than I thought.

Let’s take the Pinterest bookmarklet, the Pin It Button as an example. In every other browser you can navigate to the webpage of the bookmarklet, and drag the button which contains the JavaScript code to your favorites. For security reasons this does not work in Edge, but you can fix it.

The case was much simpler before the major update in November 2015, because the favorites were stored in the file system, in this folder:


According to the sources all over the Internet, now they sit in the spartan.edb ESE database here:


Because this is a database, you need special tools and special care to edit it, but luckily it seems that the browser also uses registry. I managed to find my favorites in this location in the registry:

HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\FavOrder\FavBarCache

Based on this, I could add the Pinterest bookmarklet to my browser with these steps:

  1. I navigated to the page of the Pinterest bookmarklet, right clicked the “Pin It” button, and then selected the Copy Link item from the menu to copy the JavaScript code of the bookmarklet to the clipboard.
  2. After this I added this page to my favorites just to have the Pinterest icon for my bookmarklet.
  3. I started Regedit, and navigated to the path above.
  4. The folder with the largest number contains the data for the favorite item I created on Step 2. I pasted the JavaScript code from the clipboard to the url key.
  5. I restarted the browser.


This is totally unofficial, not supported and not a perfect solution, but works on my machine.
