Mobile Stability

Fenix

• Nightly was crashy over the weekend due to some Sync/Application Sevices crashes
  • https://github.com/mozilla/application-services/issues/4035
• Beta have not shipped v90 yet
• Release looks fine on early data. One untracked crash in the top 10 https://crash-stats.mozilla.org/signature/?product=Fenix&signature=NS_GetAboutModuleName&version=89.1.1 crashes are all from one user. Not going to file based on the one affected user. Expect it will drop down the list as we get more data.
