Edge how to Always open favorites in new tab?

I've struggled with this problem too and finally built an https://microsoftedge.microsoft.com/addons/detail/bafanlmplgllnpdbemmppkbggiooifep to solve it.

Here’s how the extension works end-to-end:

1. Every bookmark URL is rewritten with a username newtab:
   • https://dev.to → https://email address removed for privacy reasons
2. Any request with username newtab gets redirected to empty zip file.
3. When empty.zip download is triggered, the extension immediately cancels the download and opens the original URL in a new tab.
4. Result: The original tab stays untouched. A new tab opens with the target URL. And the favicon is preserved:

The final solution may look over-engineered — and it kind of is — but it works reliably, preserves user state, and doesn't break UX.
