Firefox is a fast, full-featured Web browser. It offers great security, privacy, and protection against viruses, spyware, malware, and it can also easily block pop-up windows. The key features that have made Firefox so popular are the simple and effective UI, browser speed and strong security capabilities.

Firefox has complete features for browsing the Internet. It is very reliable and flexible due to its implemented security features, along with customization options. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.

Firefox v123.0 Changelog

Although not an exhaustive list for the final release of v123.0, the following changelog highlights key updates and fixes from the beta version, offering a glimpse into the most significant improvements in the stable release of Firefox 123.0.

Fixed

When translating web pages, we are now also translating text in tooltips (i.e. titles) and text displayed in form controls (i.e. placeholder).

Changed

Address bar settings can now be found in the Firefox Settings' Search section.

Developer

Samsung Galaxy S25 renders: the smallest Snapdragon 8 Gen 4 phone

The Network Monitor now supports saving a response body to disk through the Save Response As context menu item. This replaces the Save Image context menu item, which only supported saving images.

Web Platform

We now implement linearRGB interpolation for SVG gradients, as well as the existing sRGB interpolation. You can choose which to use via the color-interpolation property.
Previously, SVG feImage elements that pointed to SVG content required the SVG document to have a root element that had non-percentage width and height values. Such content will now fall back to use the default replaced element values of 300px width and 150px height and the feImage will no longer fail to render.
By enabling Preload and Modulepreload support, Early Hints are now fully supported.
Audio echo cancellation can now be applied to microphone inputs when the audio output is redirected to another device with setSinkId().
Firefox now supports declarative ShadowDOM, providing developers greater flexibility and improved ergonomics when working with ShadowDOMs directly within HTML.

Known problems

Some machines with older AMD CPUs may see image thumbnails incorrectly render as all black in file dialogs. If this is the case, updating the graphics driver should address this issue.
