   1 # List of Fenix Threads

   3 To profile background threads using the Firefox Profiler, you need to specify their names. It uses a case-insensitive substring match, e.g. specifying `default` will match all threads in the kotlin default dispatcher which have a name like, `DefaultDispatcher-worker-*`. This document is a list of the threads in fenix (via `ThreadGroup.list()` as of Mar 2022) to make using this functionality easier:
