@wert My guess is that it is not normal, based on the fact that by today’s acceptable business/organisational practice speedy delivery especially in cyberspace is critical.
@dotproto Add-ons as we all know extend and add addtional functionality to Firefox. I can confirm that there some companies and hospitals I know would have only been using say Chrome or an alternative browser to Firefox had it not been that the developer of the add-on they depend on for day-to-day business operations chose Firefox as the vehicle for delivering their software as an extension. Mozilla is likely to lose out completely if this attitude of degrading the developer experience continues.
There are still a lot of developers that prefer Firefox as the deployment platform. Image what happens when they can nolonger get security fixes and new features to users/clients on time because reviews are taking forever, they will simply move onto Chrome/Edge even though their preference to only use Firefox as the their platform. Mozilla is losing!
