PerfCompare just deployed (Sept 3, 2026)

Read on mozilla.org

Summary

Mozilla released a new PerfCompare version featuring a Simple View UI with checkbox column selection, expanded rows, and several bug fixes, including filter URL handling and NaN errors in stats.

  • Simple View adds checkboxes to toggle advanced columns and expand row components.
  • Filters now correctly propagate to the URL, fixing a cookie‑only issue.
  • Column widths reduced and subtest pills now link to their pages for easier navigation.
  • Removed silverman/kde warnings and cleaned up unused data in the frontend.

Anyone who uses PerfCompare for performance testing will benefit from the more usable UI and the stability fixes.
