Close to the end of the release (eg 1 week before code freeze)

• [x] Update MDN data for the Compatibility panel follow devtools/shared/compatibility/README.md

• [x] smoke test for remote debugging against version 144 (doc)
• [x] smoke test for remote debugging against the same version (version 145) (same doc)
• [x] check xpcshell debugging (doc)

Marionette and BiDi:

• [ ] close to the end of release (~1 week), based on the list of bugs fixed during the release, update Marionette release notes on MDN for 144: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/144#webdriver_conformance_marionette.
• [ ] right after the release of Firefox 144, send a mail to the dev-webdriver mailing list.

For reference: full list of Marionette and BiDi bugs fixed during the release.

Template suggestion for the Marionette email (adjust wording if relevant):

Firefox 144 has just been released, containing updates for our WebDriver (BiDi, Marionette) support.

As discussed with Julian it's too early to run the smoketests. Given that I'm out next week someone else needs to take care of it. Julian, can you please coordinate? Thanks.

Backward compat testing done. Spotted Bug 1992769 during the testing but this is unrelated to backward compatibility issues. So all good on that front.
