Former FireFox developer on the switch to their continuous update cycle.
Oh no, Chrome is doing such-and-such; we’d better do something equivalent or we’ll fall behind! We thought we needed a rapid update process like Chrome. We were jealous of their rapid update capability, which let them deploy improvements to users continuously. We had to “catch up” with Chrome’s updating capability.
Dealing with servicing on IE for years had led me to some of the same thoughts when I heard FireFox was switching to continuous updates.
