Action items

Feature Status Review

• Firefox 96 Beta
  • More From Mozilla about:preferences experiment Phase 2 wasn't able to be tested in Nightly. It's possible we could be looking at uplifts once the feature testing is complete.
  • Improve storage limits and estimations has an uplift request inbound
  • Web Locks seems to be intended to ride the trains with Fx96 but I don't believe it's been enabled on Beta. Working with Jens to confirm.
    • Enabled by default in bug 1740044
• Firefox 97 Nightly
  • Culling the feature list but overall seems like it could be a busy cycle

    • Support pdf default work
    • Segment user base per resolution and DPI scaling
