We measure the cost of updateCurrentBrowser (in FX_TAB_SWITCH_UPDATE_MS) but that's only a part of tab switching. We also try to measure the total switch time in FX_TAB_SWITCH_TOTAL_MS. However, that only seems to be recorded for basic layers, which almost no one uses anymore. -Bill _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
