I was very much excited about Firefox OS. Even purchased a phone made for Firefox OS with it preloaded. Was quite disappointed in #Mozilla when they discontinued development of that project.
@matthew - retroedge.tech they always make half ass projects then leave them mid way.. many of them had been great idea but they does not have focus on it.. a fork of firefox os was made into this by a hong kong based company its hybrid open source and closed source but its actually successful... if only mozilla had worked hard enough on the idea. https://en.wikipedia.org/wiki/KaiOS
Agreed.
