Tab groups have become one of Firefox’s most loved ways to stay organized — over 18 million people have used the feature since it launched earlier this year. Since then, we’ve been listening closely to feedback from the Mozilla Connect community to make this long-awaited feature even more helpful.


Who asked for that? Give us a way to block sites from playing unwanted sounds before bothering with stuff like tab groups.
I can’t remember when I last heard any unwanted sound from a homepage. I guess you have a problem with your settings.
And a LOT of people asked for better tab management. That’s why they made it. Want names, or are you just annoyed that a lot of people wanted something you didn’t? Here’s a tip - you don’t have to use the tab groups!
Some websites that present cookie banners or other modal dialogs like to piggy-back starting an audible video to the click that dismisses the dialog. Most videos get ad-blocked anyway, so this rarely bothers me, but last week one news article with accompanying (non-ad) video hit me with sudden audio.
I didn’t know that someone using Firefox, wasn’t smart enough to install uBlock or likewise addon…
You greatly overestimate the capabilities of Firefox’s average user.
Me. And I’m pretty sure websites are already blocked from posting unwanted sounds by default, you should check your settings
There is no setting for that and there are old open bugs about it. You can block “auto play” where the sound starts as soon as you open the page. But once there’s any user input, it’s no longer “auto” and the site can start playing sound. It can’t be blocked. Bah.
I set media.autoplay.blocking_policy=2 and media.autoplay.default=5. That seems to prevent anything from auto playing for me.
Hmm I will look into those settings. But I’d like to control it site by site rather than thru a global config.
My fix for those sites is to never visit them again. Horrible.
Ah I see. Haven’t encountered that anywhere, that sucks!
You can disable autoplay video, wouldn’t that do what your want?
I want to disable all audio from a site, not just autoplay audio. . Like muting the tab except automatically for that site.
What websites are you going to that have sounds in them like that?
lichess.org/training try playing a few moves. I want to get rid of the sounds.
