Resolved an issue affecting YouTube video playback for some users.
Like all other modern browsers, the Firefox browser updates itself in the background, requiring no action from the user. If you need to force a Firefox update to version 104.0.1, open the “About Mozilla Firefox” window (open the main menu, go to Help > About Firefox) and wait for the browser to download and apply the available updates.
Mozilla released Firefox 104 a week ago. The update improves energy consumption by hibernating browser tabs when minimized or not in focus. Firefox has historically lagged behind its competitors when it comes to energy efficiency, so improvements in this area are welcome.
