What is Mozilla Firefox?
Firefox is Mozilla's free, open-source web browser for everyday browsing and organizing work across tabs. Built-in tracker blocking is enabled by default, while tab groups, Firefox View and a customizable sidebar help keep pages and tools accessible. Reader mode simplifies articles, and picture-in-picture keeps a video visible while you use other tabs. Extensions and themes let you adjust the browser to your workflow.
The linked publisher download is the English (US) Windows x64 EXE installer, not the ARM64 build, MSI package or Microsoft Store edition. The publisher endpoint resolved to Firefox 159.0 during the recorded HEAD check; it can point to a different release later. Mozilla lists Windows 10 or later for this release. Services such as cross-device sync require a Mozilla account, but the account requirement is for those services rather than ordinary browsing.
The gallery contains older Windows Firefox interface images supplied on Softonic's product page. They show the welcome and private-window screens, not a verified capture of version 159.0. Their promotional captions are part of the original images, not independent safety or performance findings.
