At TPAC 2025, the author learned about the Chromium Issue Tracker (CRBUG), a platform for reporting bugs and proposing new features for Chromium-based browsers. Chromium, which powers major browsers like Google Chrome and Microsoft Edge, lacks sustainability tools in its developer options, unlike Firefox, which has included "Power Profiles" since version 104. These profiles allow developers to analyze the energy consumption of their websites, providing critical data for improving both performance and sustainability. The author discovered a closed CRBUG issue from 2014, where Google and Intel had begun work on integrating power profiling into Chromium's DevTools. Although code was committed, it was rolled back after an internal discussion. The ability to capture power profiles would not only equip developers with valuable insights into how their code affects energy use on real devices but could also highlight performance differences across browsers. This data-driven approach could strengthen the case for enhancing web sustainability, moving beyond theoretical models. The author expresses hope for reintroducing power profiling in Chromium, given its previous development. A feature request has been created on CRBUG to rekindle this initiative, inviting support from the community to push for its implementation. The potential impact on the frontend web sustainability community could be significant if these tools were made available in the most widely used browsers.
