Quick guide for updating release notes for Marionette on MDN

  1. Check the bugs fixed in release RELEASE:

  2. In this bug list, find the bugs which are relevant for WebDriver users.

  3. If needed, clone the mdn/content repository (

  4. Create a branch for the release, e.g. for Release 91 you might name the branch marionette91.

Bug 1687954 - Pause on JS exceptions doesn't work properly in Fission (8)
Bug 1687963 - Debugger should properly break on debugger; keyword in remote frame (8)
Bug 1665020 - DevTools Toolbox broken when navigating cross origin (20)
Bug 1568880 - Make the inspector's search field work with remote targets (8)
Bug 1681698 - Bootstrap thread actor as soon as we start registering breakpoints via the Watcher actor (20)
Total: 64 points
Why did I prioritize this way:
I did not include the storage bugs, because this is already broken today, and not Fission related.
Also did not include most of the server-side resource support. Unless there is a huge feature broken with fission because of that I don't think it will have any user impact.

First, let's look at all the call sites that don't reassign/rename anything.

StyleRuleFront::get href()

Could be replaced be returning parentStylesheet.href in the actor's form.

StyleRuleFront::get nodeHref()

Same comment as for href().


Wep Platform Tests

Update metadata

./mach wpt-update /Users/jdescottes/Development/wpt-update/

After downloading the relevant wpt-report.json files from try. Always try to take a variety of platforms (eg 1 linux 1 android, or more generally one which fails for specific conditions and a successful one).
