Microsoft Teams (browser version) is broken by Hover Zoom+

[simonrob]

Description of the problem

Having Hover Zoom+ enabled breaks the browser version of Microsoft Teams. No image hover functionality is involved – simply having the extension enabled breaks the page. I've also tried disabling sites in the extension's preferences (*.microsoft.com, *.office.net, *.skype.com), but this does not help.

Url of the page where the problem occurs (not the image url)

https://teams.microsoft.com/v2/

Steps to reproduce the problem (include image url here)

1. Enable Hover Zoom+
2. Visit https://teams.microsoft.com/v2/
3. See error message: "Oops, app failed to init!"

The following console errors are produced (which don't appear when the extension is disabled):

Hi,

I'm experiencing the same issue with Teams + Hover Zoom+ (1.0.220) on Firefox (130.0)

Edit : Deactivating by domain teams.microsoft.com or deactivating Hover Zoom + via extension settings does not seem to fix it, deactivating the extension does

@simonrob This problem occurs with me, even not using Hover Zoom extension. It's probably a Microsoft's issue.

Using Win 10 and Firefox 130.0.

Maybe you have another extension that is causing the same problem? (Which might actually help in narrowing down the root cause?)

Either way, this is not the case for me - disabling or removing Hover Zoom+ fixes the issue. Note that you have to fully disable the extension on the Firefox extension preferences page - just disabling it in the Hover Zoom+ settings does not resolve the issue.

I suspect it's caused by one of the libraries that hoverzoom includes, most likely jquery-3.2.1.js which is a very old version of jquery. Unfortunately the library can't be removed or disabled because the entire extension relies on it.
