I would say that it’s also about team output. By getting rid of a productivity tool, you will decrease expenses, but simultaneously productivity and therefore revenue will suffer.
As glassounds mentioned in the comment, Bird Eats Bug is actually covering that use case. Feel free to reach out to me directly if you have more questions: dan@birdeatsbug.com
Co-founder of Bird here. Firefox Replay seems to be focusing purely on developers, while we see usage also from PMs, QA and even customer support. So in the end developers can get more data from essentially anyone in the company.
Over time we will be adding more tools for developers. It will be interesting to see how Firefox will approach this compared to us.
