Firefox was the first browser to introduce syncing but had the problem in that few people could figure out how to configure it correctly.
Firefox Sync Reboot
Creating an account system for future Firefox connected services.
The original Sync authentication method (JPAKE) was not gaining traction with users.
The problem and how it was solved
Along with my design engineer, I was tasked with designing a conventional account system that integrated into Firefox on every platform.
What came next?
With a successful launch under our belt, we invested further into the feature.
All of these initiatives were coupled with remote user testing.
Impact
Within 10% of the time, the new Sync had attracted 10x the number of users eventually reaching 20M MAU.
