Firefox 103 Available with Better 120 Hz+ Monitors Support, WebGL Fix for Linux

One month has passed. A new release of Mozilla Firefox browser is available to download. Let’s see the new features of Firefox 103.

First, the new Firefox release improved responsiveness on macOS during periods of high CPU load, by switching to a modern lock API. It also improved the performance on high-refresh rate monitors (120Hz+).

For those prefer the pop-out video feature: “Picture-in-Picture”. It continues adding more video sites support for displaying subtitles in PiP window. They are Funimation, Dailymotion, Tubi, Hotstar, and SonyLIV. In addition, it’s possible to change subtitles font size directly in this mode.

This release also features new tool-bar navigation function. By pressing Ctrl + L to move to the address bar, user can now use Tab and Shift + Tab to switch between tool-bar buttons. And, finally hit Enter or Spacebar to activate desired button. Press the F6 key allows to quickly return to the web page from the toolbar.

For those prefer the previous behavior, that use Tab key to move between the URL bar and Search bar. It’s possible to disable the new function by disabling the “browser.toolbars.keyboard_navigation” key under about:config tab.
