Data coming from our SW experiment are indicating 7% decrease in user engagement and also, opening the Debugger panel is slower. We decided to disable SW support on all channels for now.

Data report:
https://metrics.mozilla.com/~sguha/mz/ds-455/code.1.html

This should be done in Fx80

The patch should also be uplifted to 79

We ran an experiment to assess the impact of the feature.
We could verify a significant performance impact on the opening times for the debugger.
It also led to a decrease in overall devtools usage and retention.
Therefore we are disabling the feature until we can implement it with better performance.
This should be implemented with https://bugzilla.mozilla.org/show_bug.cgi?id=1651522
