Released earlier this week, on February 11th, the Firefox 73 open-source web browser introduces various enhancement to make your browsing experience more enjoyable. Among these improvements, we can mention the ability to add a custom default zoom level that applies to all web content. Firefox comes with a 100% zoom level by default, but now it can be changed to whatever suits your needs thanks to a new ???Default zoom??? dropdown menu implemented in the Zoom section under ???Language and Appearance??? settings.
