Feature Status Review
Fx80 is looking good
- Pioneer UI still challenged for 80
- P1 bug list for uplift in Beta identified. Expected to land by weeks end. GO/no-go meeting set for Friday
Pulling together the feature list for Fx81 and confirming tracking status. So far things are looking good.
- macOS attribution has been moved out of Fx81 while the SBX team determines scope and priority
- Pioneer v2 (81) UI enhancements is light on the plans/details for Fx81. This could be due to the challenged status for the UI work in Fx80. Waiting to confirm details.
SUMO Report
- [roland] nothing to report. I heard from twitter and Romain Testard there is an issue with CCleaner wiping out add-on data but I don't see any reports of this
on SUMO from July 31-August 3rd ; I will check today's questions. Is there a bugzilla bug? roland will file a 3rd party software bug
- https://mobile.twitter.com/ma1/status/1289572818078691330
- https://community.ccleaner.com/topic/58613-problem-with-firefox-79/?tab=comments#comment-321277ner
- workaround from CCleaner staff: quick update: while we work on getting a fix out, Firefox users can use this temporary workaround:
- If cleaning with Custom Clean: ensure the Internet Cache Firefox cleaning rule is unchecked before running a Custom Clean.
- If cleaning with Health Check: uncheck the Temporary Internet Files category in the 'Privacy' section after analyzing when you run Health Check.
