Worked on the SeleniumHQ/selenium repository to expand archive handling for Firefox Nightly builds on Linux by adding support for XZ-compressed files. Refactored the existing BZ2 uncompressor into a generic tar uncompressor and implemented a new XZ uncompressor using the xz2 crate, enabling selenium-manager to process XZ-compressed archives. This approach reduced code duplication and established a scalable decompression path, laying groundwork for future archive formats. The work focused on compression and decompression, dependency management, and file handling in Rust, improving the CI testing surface for Linux builds and enhancing automation for handling new Firefox Nightly archive formats.
