  • Added some notes to the in tree docs

WebExtension APIs

Lint

If you run `./mach lint` in the top-level directory of a repository, with no paths specified, it will now default to `--outgoing --workdir`, rather than doing a full lint.

Messaging System

• Support showing different about:welcome default experiences based on some targeting, e.g., Windows build version, that can still be remotely configured
• Various fixes in preparation for rapid turnaround from 87 release “Pin” experiment during 88 beta: landing strings, mac size regression, icon disappearing

Password Manager

• Bug 1688213 Enable "signon.management.page.fileImport.enabled" for all channels fixed and in 88.
  • Import logins from CSV is in beta! Congrats to :petcuandrei for taking this feature from a UX spec and aspirational bugs to implementing and now shipping a feature that rounds out our whole story around login management.
  • We now import and export logins, allowing you to round-trip from other browsers, other password managers, backed-up profiles or any other exotic scenario for which you can prepare a comma-separated values sheet, with at least password and URL columns for successful import into Firefox.
  • We also have the ability to delete all, so the cost is low to play around with it and file bugs.
• :dimi landed Bug 1166995 - Run login capture code when a form or a formless password field is removed from the document tree. This fixed some long standing issues with prompting to save passwords on sites e.g bigcommerce.com, and no doubt many many others we were never notified about
• Several string, style and context menu changes ahead of MR1/Proton, thanks especially to Prathiksha for jumping in to help
