==Plans==
=== Regression Duty ===
Current areas of regression duty:
* Watch b2gperf start up times https://datazilla.mozilla.org/b2g
* Watch fxos-pert alerts. Currently, limited in scope to start up time regressions.
* Map of Gecko revisions reported by datazilla to their correct revision https://people.mozilla.org/~asasaki/vcs2vcs/gecko-dev/gecko-mapfile
* Get access to Jenkins. File a bug like [https://bugzilla.mozilla.org/show_bug.cgi?id=1036477 bug 1036477]
