It would be good to have a "click to unmute" option as the default for how a browser handles audio. Click to play works well for Flash plugins, it might be good for audio as well.
I wish for a time disabled extension. Basically turning the browser into an html/css based image renderer. No more animated ads, autoplay audio/video. Heaven.
I'm sure you're joking, but here's a blast from the past (I'd forgotten about it, anyway): you can set `image.animation_mode` to `none` in Firefox for that.
I wasn't even joking, I'd really love to try purely static (beside the old guard <a> <form> elements) webpages and am delighted there's such an option, this is amazing, thanks.
I'm glad it was helpful! In case you're interested in the other hidden switches that you can toggle if you're willing to void your warranty, there's a reference at http://kb.mozillazine.org/Firefox_:_FAQs_:_About:config_Entr... . (I'm not sure how up to date it is, though.)
