MKVToolNix Forum isn't displaying correctly with Microsoft Edge in Windows 11

I’ve run into a very strange problem when viewing this MKVToolNix forum with Microsoft Edge in Windows 11 25H2. The forum displays in a very vanilla style, almost like it is text only. On the same device, I opened the forum with Google Chrome and Firefox and the forum display without. I tried on three different Windows 11 25H2 devices, each connected to a different network (all on different ISPs) and all had the same problem with Microsoft Edge. I also tried disabling all extensions and running in a private session in Microsoft Edge, but still hit the same issue.

When I open the developer’s tool in Microsoft Edge I see the following errors under Console:

chrome-extension://k…/apps/pageView.js:1 Uncaught (in promise) TypeError: Failed to fetch dynamically imported module: chrome-extension://kiiaghlmeikbpmeabhilfphikfcefljn/notifications/injectors/injectNotificationScript.js
chrome-extension://k…ctors/apps/pie.js:1 Uncaught (in promise) TypeError: Failed to fetch dynamically imported module: chrome-extension://kiiaghlmeikbpmeabhilfphikfcefljn/notifications/injectors/injectNotificationScript.js

I checked the support forums over at the Discourse website and also searched the Internet but I can’t find anything that is causing this problem in Microsoft edge with the forum.

I cannot help you with that, sorry.

Those console messages refer to installed browser extensions. Those have nothing to do with the site.

That’s what I thought at first, so I tested with all extensions disabled, and the issue still occurred. Looking at the debug tools, it looks like its something going on with injectNotificationScript.js that is coming from the site.

At the very least, can anyone else test with Microsoft Edge in Windows 11 and see if the issue occurs? This will help confirm if the issue is with something local or something with the site. As mentioned, I tested on 3 different devices on 3 different networks and it occurred each time, but if others could also test out, it would help determine where the problem is at.

I just tried on my wife’s computer and the site is working fine in Edge. The common thread here is that I do have all the same extensions in Edge across my 3 different devices. Maybe it is extension related but you have to completely uninstall the extension instead of just disabling it. I will do some more testing and report back.

I ended up clearing out all web browser data (cache, cookies, etc.) and it started to work. Very weird though that this was occurring on 3 different devices, and that in private mode, which is supposed to not have any web cached data, also didn’t fix it.
