  • Alex improved the JSTracer in the DevTools console by adding setInterval/setTimeout/requestAnimationFrame callbacks and DOM events in the traces (bug)
    • A trace being displayed inside of the Firefox DevTools console. Several frames in the trace are highlighted as having been entered via requestAnimationFrame.
    • You can test the JSTracer by setting devtools.debugger.features.javascript-tracing to true in about:config, and clicking the tracer icon in the debugger pane.
  • Alex and Hubert are working hard to make the Firefox Debugger much faster
    • Alex optimised our parser worker computations, bringing nice wins (e.g. 5% to 10% faster to open a large file) (bug)
    • Alex updated babel do benefit from performance improvement made in the library lately, which were validated by DAMP results (e.g. debugger is than 10% faster to open a large file) (bug)

    hey, the URLs sanitizer that strips the tracking is really cool, could potentially replace many Add-Ons. How does it work? Is it customizable?

    I think I’ve found a bit of documentation on the Mercurial repository at this link: https://hg.mozilla.org/integration/autoland/file/28009d65937bef7bb0d043dbbb1e61ff13a263a7/toolkit/components/antitracking/docs/query-stripping/index.md
