Toolbox usage over time
Firefox Developer Tools
What is this?
This graph shows Firefox Developer Tools toolbox usage over time, totaled into weekly counts and based on the Telemetry measure 'DEVTOOLS_TOOLBOX_TIME_ACTIVE_SECONDS'. For simplicity, Aurora and Nightly build counts have been combined. This measure gives us 'How long has the toolbox been active (seconds)' for a given session. These counts are then totaled up and divided into two ranges:
- Number of sessions with more than 5 minutes of use.
- Number of sessions with more than 30 minutes of use.
What this tells us:
We should see an indicator for overall devtools usage over time, hopefully (and apparently) increasing over time.
- The tuning of these numbers (time open per session) to the two ranges is based on some assumptions:
- If the toolbox is opened for more than 5 minutes, it likely wasn't opened accidentally.
- If the toolbox is opened for more than 30 minutes, the user is a web developer using our tools for serious work.
- The number of sessions does not directly correlate to the number of users.
- As Telemetry data collection is only on by default for the Aurora and Nightly channels, only Aurora and Nightly data is included and totaled here.
- Beta and Release data is not used because it a) can involve very large numbers of reports, and b) is very inconsistent, for example compare Release data with Aurora data for the same measure.
- I've noticed that Telemetry data hosted on S3 is sometimes sketchy, so here is a screenshot of what this graph typically looks like.
