If you are a Mozilla Firefox user, you’ll be happy to know that you can now select multiple tabs and take specific actions in bulk. For example, you can select several tabs at a time, then mute, move or close them all at once, without having to do the same action for each tab.

Even though Mozilla Firefox isn’t the most popular Internet browser on the market, it is certainly one of the best browsers available. Especially if you have privacy in mind. Apart from being a privacy-focused browser, it’s also faster than Chrome in a lot of areas and far less resource hungry. Speed wise Firefox and Chrome are neck and neck for most website loading times, apart from YouTube, but that’s an entirely different story.

Although it has taken longer than it should have, Firefox now has the ability to select multiple tabs at the same time, allowing you to quickly and easily select and close, mute or move tabs. Sadly the feature isn’t enabled by default just yet, so you’ll need to use Firefoxes flags menu to enable the option. So follow along as this article shows you how to do so. Just make sure you have Firefox version 63 before continuing.
