FaceTime on the web requires Chrome or Edge, no mention of Firefox
It may seem an advantage to use the latest cutting edge features of a single platform, instead of using well established standards which are compatible with every browser. Sure, you are going to leave out some small minority of users, but you gain access to many new features.However, you are helping push the web become an increasingly centralized place, controlled by just a few entities, with interests which are very different from yours.You may think that there is no harm in doing so. Most people use Chrome anyway. And what difference can one more web app make?However, it is exactly this laziness by skilled developers, who are the only that understand the problem, which brought us to the current situation. There is no way to fix this problem, if the people that understand it do not take a stand.Next time that your manager asks you if you can have that sweet feature, instead of saying "sure, we just need to drop support for Firefox", please consider trying to explain what are the consequences in the long term.I know this isn't easy for many people, which do not feel comfortable questioning orders or plans. However, this is our responsibility. Nobody else is going to care, if we do not care.
