The Mozilla Foundation today launched a new version of Firefox that may prevent some websites from asking to send notifications to their device, as reported by Ars Technica. In addition, this version of Firefox, launch number 59, also prevents some sites from unexpectedly accessing the camera, microphone and the location of your device.
The new feature prevents your notification center from filling up with lots of news from various sites. When turned on, all websites by default will have those requests blocked, but you can tell Firefox to accept notifications from trusted websites.
To manage your notification permissions in Firefox 59, go to options in Windows or preferences in Mac. Then click on "Privacy and security" and look for the marked permissions section. From here, you can individually manage your location, camera, microphone and notifications.
Other elements mentioned in the Firefox 59 release notes include annotations on screenshots in the browser, different ways to customize your tabs and windows, and the following performance updates:
Faster load times for content on the Firefox home page
Faster page load times loading from the network cache or from the cache on the user's hard drive (Race Cache With Network)
Improved graphic representation using Off-Main-Thread Painting (OMTP) for Mac users (OMTP for Windows was released in Firefox 58)
Firefox 59 is now available for all platforms.
