Introduction

This project is to support events and related interfaces for handling hardware pointer input from various devices including a mouse, pen, touchscreen, etc. There's implementation prefed-off on Nightly due to lack of stability. We will start from enabling the feature for Desktop again on Nightly then on Fennec.

Archive & History

Milestone 2 To enable PE on Windows on Nightly 53
Target schedule Riding Firefox 53 Nightly (on track) (Due to Chinese new year, we are considering pref-on right after the holidays, i.e. 54)
Status DONE
Details
  1. Enabled on Nightly 54
Issue Description Status Comments/Corresponding Action
Ship to Windows only first QA suggested we could consider to ship only to Windows first if PE is going to be better than the current touch events Closed
  • Wait for QA P1 & P2 report first, then ask Reviewer to see if any concerns
  • If suggestion accepted, we will merge two phases into one.
  • [Reviewers' feedback] It's not suggested we ship this feature to a single OS first. We should ship it to Desktop on all OSes together, then Fennec.
Milestone 3 To enable PE on Linux on Nightly 55
Target schedule Riding Firefox 55 Nightly (on track) - turn out to be enabled on 56 Nightly due to Quantum resource allocation and Fingerprinting sec review
Status DONE
Details
  1. SV delivered 55 mid-nightly report (YELLOW) and pre-beta report (GREEN, recommend to ship)
Issue Description Status Comments/Corresponding Action
Linux testing support on SV side Need to confirm SV's resource and testing equipment Closed
  • SV will keep testing this feature for a sign off report.
  • SV doesn't plan to buy a specific linux device, we will send one to them once Taipei QA finishes the 1st round testing for us.
Pending review on https://bugzilla.mozilla.org/show_bug.cgi?id=1324956 Reviewer doesn't think we should do this now, and it's not in his priority Closed
  • After discussion and QA testing, we agreed that it's not within the scope of MVP as current firefox doesn't support linux touch by default.
Fingerprinting Need to have security peers feedback on fingerprinting exposure Closed

Get conclusion on [Bug 1363508 - Consider how to do Anti-fingerprinting for Pointer Events]. Bug 1363508 isn't a blocker to ship PE but we need to get it fixed in FF 59 considering the plan for the anti-fingerprinting project.


Milestone 4 To enable PE on MAC on Nightly 55
Target schedule Riding Firefox 55 Nightly (on track) - turn out to be enabled on 56 Nightly due to Quantum resource allocation and Fingerprinting sec review
