EdgeExtensionsBlazor

This repo contains some Edge/Chromium Extensions that use Blazor (Web Assembly).

All of these extensions make extensive use of Blazor.BrowserExtension, and would not be possible otherwise. If you are interested in developing extensions using Blazor, I strongly encourage you to check it out.

Blazor New Tab

This is a new tab page extension that is similar to the new tab page for Microsoft Edge.

• Background image uses the Bing image of the day and updates along with Bing.
• Allows you to view previous bing images of the day.
• Creates quick links via a specified Book Mark folder. Unlike with Edge, you can have as many quick links as you want.*
• Features app link menu for Microsoft 365. Some of the links are different than the one for Edge (I.E. Visual Studio and Azure).
• Allows you to search using your default search engine.
• You can rearrange Quicklinks / Bookmarks by dragging them on top of each other to swap their places.
• Renaming and Deleting Quicklinks / Bookmarks is possible via the hover buttons on the edge of each Quicklink.

*Having a lot of Bookmarks in a particular folder will however make the page get bigger and may require you to scroll down.

Note: By default this extension uses Peapix.com's API for the Bing images of the day. This is because Bing's official API has CORS restrictions. Unfortunately, Peapix does not return the quiz question links for the museum cards on the new tab page. Note 2: In the settings, you can use the old version of the extension's CORS Proxy, AllOrigins.Win for the Bing Images, but I do not recommend using it since AllOrigins.Win is not reliable. I am looking into a different proxy.

Get Blazor New Tab from the Edge Add-Ons Website:

• If you are using Microsoft Edge, simply visit the link below to install the latest public release of the extension (only available in US / English):
• Blazor Edge New Tab - Edge Add Ons

How To Build:

• This project has no external dependencies besides the ones Blazor/Asp.NET rely upon and one specific NuGet package for allowing Blazor to to run as a Browser Extension.
• You can build it using either the Dot Net 10 SDK CLI, JetBrains Rider or Visual Studio 2026 (latest version; edition does not matter).
• When you build the project, the output folder will contain a browserextension folder. This is the folder that you need to load for the unpacked extension via your extensions menu in Edge/Chromium

Basic Usage Instructions (For Blazor New Tab):

1. Load the extension as you would any other standard unpacked extension

2. Your new tab page should be replaced with one provided by the extension.

3. The new tab page should load the bing image of the day, assuming Peapix (or allorigins.win) and bing are available.

4. If you are running the Extension for the first time, it will prompt you to select a Bookmarks folder to use for your Quicklinks. You can change this in the future via the button in the settings menu in the upper right hand corner.

5. The web search should take you to your default search provider page (preferably Bing) if you type in text into the web search text box and hit enter or click the magnifying glass / search button.

6. If you click the filter button on the web search text box, the new tab page should switch to filter mode and let you type in the name of a favorite. When you hit enter, your favorites / quick links will be filtered based on what you typed.

7. If you delete all the text from the web search text box and hit enter again while in filter mode, it should clear the filter and bring back all available favorites.

8. The co-pilot button on the search bar should navigate you to the Bing Co-Pilot / Bing Chat website where you can use Co-Pilot.

9. The Waffle button in the upper left hand corner should display a drop down with links to various MS365 apps and services.

10. The rewards button / badge in the upper right hand corner (to the right of the settings button) should take you to the MS Rewards site.

11. You can rearrange bookmarks by swapping their positions by clicking and dragging QuickLinks on top of eachother.

12. You can rename or delete Quicklinks (bookmarks) by the hover buttons on the edge of each Quicklink.
