Here are a few useful add-ons for Microsoft Edge Chromium: (This is mainly a reference for myself)
ARCHIVE PAGE
Adds a button to the Microsoft Edge toolbar. When clicked, it sends the URL of the current tab to archive.today to preserve a snapshot of the page, and opens the result in a new tab. Also includes Link context menu to Archive or Search, Page context menu to Search. Archive URL can be bookmarked for future reference, shared, whatever. Uses HTTPS for security.
(For similar functionality on Android, check out Share2Archive in the Play Store.)archive.today is a time capsule for web pages. It takes a ‘snapshot’ of a webpage that will always be online even if the original page disappears. It saves a text and a graphical copy of the page for better accuracy and provides a short and reliable link to an unalterable record of the web page

DISABLE HTML5 AUTOPLAY
“Disable HTML5 Autoplay” disables HTML5 audio and video autoplaying.Now any video is blocked until you click the agreement button.
In addition to removing the HTML autoplay attribute from media elements, “Disable HTML5 Autoplay” also hooks into the media’s JavaScript API. This allows for restrictions on media control and simulation of expected behavior to ensure that all pages behave normally. Main and most requested feature: this blocker has a customizable white list, so you may add your favorite sites to exclude from blocking autoplay. To deactivate a function, simply uncheck the related item from toolbar-panel. With this extension you will never have to worry about videos auto playing in the background. In addition, the video will be automatically buffered if necessary.
