Mobile Stability
Fennec
- Crash rate is calculated based on usage hours (the time Firefox is actively used).
- Usage hours will be significantly lower on Fennec than on desktop Firefox, so we can't compare mobile rates to desktop rates.
Fenix
- we had an ANR spike earlier this week
QA
Nightly
- feature prioritization is in progress, so far so good
Aurora / Dev Edition
Beta
- Windows Default Browser Agent will be ready in the next Nightly, still targeting March 18, awaiting approval from leadership
Mobile
