Better profile management coming to Firefox
Firefox has long had support for multiple profiles to store personal information such as bookmarks, passwords, and user preferences. However, Firefox did not make profiles particularly discoverable or easy to manage. That is about to change; Mozilla has announced that it is launching a profile-management feature that will make it easier to create and switch between profiles. According to the support page for the feature, it will be rolled out to users gradually beginning on October 14.
[$] Upcoming Rust language features for kernel development
The Rust for Linux project has been good for Rust, Tyler Mandry, one of the co-leads of Rust's language-design team, said. He gave a talk at Kangrejos 2025 covering upcoming Rust language features and thanking the Rust for Linux developers for helping drive them forward. Afterward, Benno Lossin and Xiangfei Ding went into more detail about their work on the three most important language features for kernel development: field projections, in-place initialization, and arbitrary self types.
