Mozilla Firefox is getting an audio tab indicator, and it’s already available in Firefox 42 beta

A few days ago, we told you that Mozilla has introduced its new anti-tracking feature in the improved Private Browsing mode, in the latest beta version of its browser, Firefox 42.

However, it appears I did miss one key feature which was also shipped in the version, Audio Tab indicators.

I came across the feature, while I was reading an article at VentureBeat. This may not be useful if you are a casual browser, but power users will find it to be a great boon. This is especially the cause when you visit a good website and an annoying auto-play video begins blaring loudly, with some nonsense you wouldn’t normally care about.

Now if you only have a few tabs open, it may not be a difficult job to find out from which tab the noise may be coming from. But imagine the scenario when a dozen tabs or more are open, it would be one hell of a job to find the noisy tab and mute the video or even close the tab altogether. This is where the Audio Tab comes in to prove its usefulness. Firefox will place a speaker icon on the browser tab with any sound content is being played, thus making it easier to identify the noisy tab.

Another cool feature is that the Audio Tab Indicator also allows you to mute the tab with just one click of the mouse, and that can be done even without switching to the tab. This makes it all the more welcome, and I can’t wait for this feature to arrive in the stable version of the browser.

Speaking of which, Mozilla Firefox 41.0 was released to the stable channel, earlier this week, and you can read our write-up about it for more details.

However, what intrigues me is how Firefox will evolve, when Mozilla begins upgrading the browser with Electrolysis technology, which will improve the way the browser handles the RAM, but also breaks the functionality and compatibility of existing Firefox add-ons. For a list of the add-ons compatible with Electrolysis, do take a look at our previous article. This could well be further hindered by the new WebExtensions API, which requires developers to rewrite the entire code of their add-ons,

Mozilla will also begin to unleash its mandatory add-on signing rule beginning from Firefox 44, which may also end the functionality of more add-ons, especially the ones not available in the official repository.
