Ubuntu releases new version, Firefox continues to be the default browser
Mozilla is based on transparency, choice, and trust. In addition to providing excellent user experience, it also strives to enable Firefox to be cross-platform, multi-device, or multi-operating system. Mozilla and Canonical updated their partnership today, allowing Ubuntu to continue using Firefox as its default browser. Mozilla is honored to have been cooperating with Ubuntu for more than 10 years. Like Mozilla, Canonical is also an open-source and community-assisted organization.
The latest Ubuntu version 16.04 will be imported into the "snap" encapsulation architecture. Using this snap format, Mozilla can continuously optimize Firefox for Ubuntu. Just like the release cycle of Firefox, even if the main release date of the operating system has passed, the snap format allows Linux users to enjoy the latest features at any time, especially important security fixes.
Earlier versions of Firefox were released along with the new version of the operating system. However, users of the old version of the operating system can also enjoy the latest features through the snap format. Within this year, Mozilla will provide Firefox in snap format, so that users can easily push their browsers to users without relying on other media to receive updated documents.
