Looks like the solution could be that either they in Microsoft finally find the remnants of their conscience and make Skype For Web support all other browsers, or something gets changed in the browser itself on the level other than UA, so that Skype really-really thinks that it is opened in Chrome 73+ (but ofc not sure if this is something that is possible). Now its only the functionless Edge that I don't have on my Windows 7 anyway, or Chrome the garbage that I will not let anywhere close to my computer. First and foremost, in Opera browser launch the Developer Tools menu or simply press Ctrl + Shift + I on the keyboard.

What can I do with Skype for Web Select your profile picture where you can: Update your status to Active, Away, Do not disturb, or Invisible. Learn more about the supported browsers for Skype for Web.

You’ll need to use Microsoft Edge, Chrome or other supported browsers. Although it will eventually support Chrome-like extensions, this. You can sign in to Skype for Web and start chatting right away. The methods people used before no longer work, neither UA Switcher extensions nor changing the UA via browser launch from command line. Skype for Web erroneously identifies it as Chrome and tries to install the Chrome extension. I supposed to have one today actually, and guess what, what a surprise, I failed to join it, because of all this Microsoft's ****** ******, as Skype audio/video calls support neither Opera nor Vivaldi! I've already abandoned Skype after they killed its desktop version a few weeks ago (still choosing between the alternatives: Wire, Linphone and qTox), but sometimes I have to use at least its web version, as unfortunately it used on my job for meetings. Skype for Web uses the ORTC API (which is related to the webRTC protocol, which means that you can use browsers that support the API and the H.264 video codec for audio and video calls. Time goes by, and they don't think to stop. Microsoft has done enough shit during the last 5-7 years.
