I am on FF 139.04. I have been there for Months. Suddenly, I see an icon for TAB GROUPS amongst my tabs. I am not able to find how to get rid of the seemingly automatic grouping.

1. How do I get rid of this icon appearing?

2. What does delete tab group do? That is, does it delete the group OR the group and all the tabs in it?

3. Where is documentation for how to use tab groups?

when i MUTE some tabs (using the native FF tab mute icon on the tab) sound is muted for just that tab. HOWEVER, it also mutes ALL SYSTEM sounds.

This occurs both with my regular profile and using a default profile for my version (which has NO ADDONS).

It seems to depend on the type of delivery of the music. (Or something!)

This occurs for the following URLs:

   https://14223.live.streamtheworld.com/WRTI_CLASSICAL.mp3
   https://areena.yle.fi/podcastit/ohjelmat/57-llL6Y4blL

However, rather interestinly, it DOES NOT OCCUR for the "standard" WRTI radio station:

   https://www.wrti.org/classical-playlist-search

it seems UNREASONABLE THAT A WEB SITE SHOULD BE ABLE TO EXERT ANY CONTROL upon system sounds.   So, I must presume this is a FF bug; however, I have not posted it as such (having no confirmation from others).
