Mute tab icon changed?

[AccountCreatedF]

The icon for muting a tab that is making noise seems to have changed to have a circle around it and be darker in that circle. Is there any way I could change it back?

Hello

An subject https://www.reddit.com/r/firefox/comments/1gf6uog/another_update_another_bad_uiux_decisions

Of course, this is not the expected answer, nevertheless take a look at https://www.camp-firefox.de/forum/thema/138504-tab-mit-audioinhalt-ist-diese-darstellung-normal-oder...

https://www.userchrome.org

If you want to try, userChrome.css and others https://www.w3schools.com/colors/default.asp

/*Lautsprechersymbol größer und ohne Hintergrund */
.tab-icon-overlay {
  border: none !important;
  background-color: transparent !important;
  transform: scale(1.7) !important;
}

/* Lautsprechersymbol weiß bei Sound */
.tab-icon-overlay[soundplaying] {
  fill: green !important;
}

/* Lautsprechersymbol grau bei stumm */
.tab-icon-overlay[muted] {
  fill: red !important;
}

Restart firefox if you modify userChrome.css

This works really well. Thank you.
p.s. Your suggestion also led me to learn about the page "about:restartrequired" which relaunches with all prior tabs loaded!

I can barely tell the difference between the default icons, which seems like a significant accessibility bug with this feature. 😞
