Today

• Firefox Translations!
  • Metabug to file bugs against
  • Training pipeline
• Back to WindowsJumpList!
  • A lot of the complexity that we're dealing with architecturally is because we're trying to maintain the old backend while adding the new capability with a new backend, but the two backends share some infrastructure.
  • What I want to do is determine if we can do a better job of separating out the jumplist backend by reading a pref at runtime and choosing the right implementation.
  • Rename nsIJumpListBuilder to nsILegacyJumpListBuilder
  • Add createLegacyJumpListBuilder to nsIWinTaskBar to use the old mechanism
  • Create a new nsIJumpListBuilder and implement it using the code we've got
  • Have createJumpListBuilder in nsIWinTaskBar use that
  • Update WindowsJumpLists to choose the right builder based on the pref and treat them correctly based on that pref.
• Let's work to retire the old migration wizard

Glossary

• BHR - “Background Hang Reporter”, a thing that records information about when Firefox performs poorly and sends it over Telemetry
• e10s ("ee ten ESS") - short for Electrolysis, which is the multi-process Firefox project
• CPOW ("ka-POW" or sometimes "SEE-pow") = Cross-Process Object Wrapper. See this blog post.
• Deserialize - "turn a serialized object back into the complex object”
• Serialize - "turn a complex object into something that can be represented as primitives, like strings, integers, etc
• Regression - something that made behaviour worse rather than better. Regress means to “go backward”, more or less.
• l10n - localization
• a11y - accessibility
• i18n - internationalization
• k8s - kubernetes
