Jump to navigation Jump to search

This is for triage of the very latest bugs. Welcome to the firehose! This is an exciting group of bugs to look at. You really get your finger on the pulse of the Mozilla community.

The lists point to bugs filed in the last 24 hours. Usually this is around 50-100 UNCONFIRMED bugs on weekdays, and more that are NEW or quickly move to other statuses, but the number fluctuates over the course of the day. Many of them will really be support questions, or duplicate bugs. Incoming bugs that are untriaged are a good focus point: IncoUNCO bugs!
