X-Notifier for Microsoft Edge

I had use FF for a long time, but recently FF isn't working well after all those updates and becomes increasingly slow. Now I switched to Edge and this browser is faster and more stable.

Is there any possibility to create x-notifier for edge too or do you just stay with FF, Chrome, Opera???

Microsoft products are a different programming environment and apparently much more complex, so the developer has never had any interest in developing a version of X-Notifier for Internet Explorer... or for Edge.  People have asked before and been turned down.

If you want to use many custom scripts, you'll need to switch to Chrome browser (or Opera, perhaps... or Safari, if you use an Apple computer)...  the Firefox version will soon become more limited due to changes in its programming environment.
