These Weeks in Firefox: Issue 90

Highlights

  • The password manager now supports importing logins in CSV format. Import logins from CSV is in beta! Thank you to Andrei Petcu for contributing this great new feature. 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.

Developer Tools

Fission

  • Decided not to fix the disabled WebPayments UI for Fission.
  • Closed the frontend fission metabug!

Installer & Updater

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

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

PDFs & Printing

  • Bug 1682162 – Print margin unit should be localized. This landed in 88, so now margin units are displayed according to the unit indicated by your printer.

Performance

  • dthayer is also working on various improvements and bug-fixes for the Pre-XUL Skeleton UI
  • florian added some very handy profiler markers for CSS animations and transitions
  • The Pre-XUL Skeleton UI experiment will be wrapping up next week, and we hope to have some data on how it impacts new and existing user behaviour
  • The Process Priority Manager was originally going to be disabled for Fission, however we’ve found it’s still useful on low end hardware. Now we are working on adapting it to work on subframes.
  • mconley spoke with k88hudson about using Nimbus / ExperimentsAPI to run an about:home startup cache experiment
    • Originally, we had a Normandy experiment set up for about:home startup cache, but it turns out Normandy sets its prefs too late. Nimbus seems to do it earlier, which is good for us.
  • barret fixed an AsyncShutdown bug for IOUtils, which should be the final blocker to remove the remainder of the OSFile uses in the tree! \o/

Before and after the CPU utilization changes in the graph. You can notice that there are no activities in some areas in the new graph.

Picture-in-Picture

  • Molly [mhowell] and Micah [mtigley] are working on setting up a foundation for site-specific video wrappers (Bug 1670108)
  • Oliver [popeoliv]
    • Landed some documentation for the Picture-in-Picture addon (Bug 1695266)
    • Started investigating how we can allow the Picture-in-Picture player window to continue playing even after the parent tab closes (Bug 1561301)
  • Swapnik [katkoor2] submitted a patch where we prevent showing the Picture-in-Picture toggle button for videos with an invalid duration (Bug 1697616)

Search and Navigation

  • If a search engine that is set as default is removed, we will now revert to the region/locale default if it is not hidden, or we will try revert to a general search engine.
  • Fixed an issue where updating an add-on which defined a search engine, and changing the search engine name could cause issues.
  • nsISearchService.addEngineWithDetails has now been removed. This had become a test-only function, but conflicted with future work. Please prefer SearchTestUtils.installSearchExtension instead.
  • Cleaned up the Search Telemetry in tree documentation – Bug 1698847
  • Improved Address Bar handling of pasted strings containing white spaces – Bug 1327589
  • Fixed a problem with editing the case of the url ref fragment – Bug 1693320
  • Fixed a problem causing Tab to Search results to appear at the wrong index – Bug 1697517
