Mobile Stability

Fenix

Feature Status Review

• No challenged or at risk features for either Beta Fx85 or Nightly Fx68
  • Waiting on a few landings in Nightly around; newtab update, download token, backwards compat of the infobar, and moving WebGL drawing to the GPU process.

SUMO Report

• No major updates. Currently busy reviewing deplatforming post plus VPN 2.0 launch
• Any concerns that SUMO should be tracking mentions on?
  • Tracking Print UI mentions

Pre-release channels activities

• Windows download link on https://beta.mozilla.org was changed from the stub installer to the full installer (the stub installer replaces Firefox Release with no option to install beta alongside Release)
• Firefox Beta notes now incitates people to report bugs to bugzilla
• Link to Firefox Beta twitter account added to beta release notes and beta download page (replaces a dead "feedback" link which was just a blank page)

Roundtable & Special Topics

• 86 features list is light, the 2 items added at the moment were not in Trello, the AVIF change probably should
  • AV1F is in the "Web Platform" trello board. For security reviews I have to look at both.

Post-Mortem (Tues 2wks from GA Release)

• 84 PM next Tuesday
