For enterprise users, there's a new beta version of Firefox Quantum. This version offers certain administrative controls that will empower users to deploy pre-configured installation tools on Firefox for Windows, Mac, and Linux.
Firefox 59 brings several performance improvements such as faster loading of content by loading it from networked cache or cache sourced directly from the user's hard drive. Also, Off-Main-Thread Painting (OMTP) comes to Firefox for Mac which will offer better graphic rendering.
Firefox Screenshots gets annotation and cropping tools that would allow the user to draw, highlight, or re-size the screenshots.
Other features coming to the Firefox browser for Desktop
With the Firefox version 59 update, one gets improved Real-Time Communication (RTC) capabilities, support for W3C specs, and the ability to block unknown websites from sending notifications. Importantly, to prevent cross-tracking, Firefox Private Browsing mode will now remove path information from HTTP referrers.
Firefox 59 on Android brings support to use the browser as an assist app, allowing quick searching by pressing the home button on smartphones. Notably, Firefox for Android also gets the same Firefox Private Browsing upgrades as previously mentioned for desktop.
Also, the app now supports HTTP Live Streaming video playback and comes with the ability to lock full screen video in landscape mode.
