Please report that build failure as a bug with more details! We likely are accidentally intermixing assumptions about #ifdef DEBUG and #ifdef DEBUG_FRAME_DUMP or something Anyway -- as it seems you noticed, our frametree-dumping code is guarded by that exact #define -- DEBUG_FRAME_DUMP -- which means the code is not present in any of the builds that you tested. (Firefox, Nightly, DevEdition.) So, the code is only present in debug builds, or builds with MOZ_DUMP_PAINTING enabled at compile-time. Your best bet is probably to: (1) Build or download a debug version of Firefox. (If you build it yourself, put ac_add_options --enable-debug in your .mozconfig. Or, you can download a debug build from today at http://archive.mozilla.org/pub/firefox/tinderbox-builds/mozilla-central-macosx64-debug/1460109722/ ) (2) Start the layout debugger (Tools|Layout Debugger) -- this menu option is only present in debug builds. (3) Load whatever site you want in the tiny layout-debugger browser that appears (with minimal-UI) (4) Dump the frame tree (to your terminal) using Dump|Frames in the layout debugger window. ~Daniel _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
