Mozilla has recently released Firefox 149, introducing several new features for users. The update brings a new Split View functionality, allowing users to display two web pages side-by-side within a single browser window. This method is described as a cleaner approach compared to using separate browser windows, as it consolidates tabs and reduces duplicated window chrome. Additionally, Firefox 149 now includes a free, built-in Virtual Private Network (VPN). The release also features a welcome Linux-specific change aimed at improving integration, though specific details of this enhancement were not provided in the announcement.
