Feature Status Review

Firefox81

• [challenged] PDF Form Fill - high impact defect found recently. Patch expected today.
• [challenged] Move Search TopSites into Remote Settings - Working to resolve a few issues identified by QA. This is high priority work that leadership is looking to have in Fx81. Engineering expects to have resolution on these outstanding issues very soon.

Firefox82

• [challenged] Modernized print UI - Slipped from Fx81 (to Fx82) due to outstanding work. This was a known risk. Keeping as challenged as the work hasn't yet landed and we are heading into Fx82 Beta.
• [challenged] Improve QB (V2) Search Discovery : Search Shortcuts - Several bugs (20?) identified during dogfooding. Work through thriage of these issues. Still targeting Fx82 but may slip to Fx83.
• [challenged] Login Capture Doorhanger V2 - Planned work for Fx82 is challenged as it is not yet complete and the assigned engineer was shifted to other projects. Expected to slip from Fx82. Expect decision during a planning meeting later today.
