- dthayer
- Landed a fix to the background tab process manager to make sure it only impacts web content processes.
- mconley and dthayer are testing enabling the background tab process manager. If all goes well, we might try to enable it just on Nightly to see how it shakes out.
- You can test it yourself on Windows by creating a new pref, dom.ipc.processPriorityManager.enabled, and setting it to true.
- Has patches up to shift more code over to the new batched Places observer API
- Has a patch up to get rid of some hashtable lookups and mallocs when using SVG and CSS filters
- Landed a fix to the background tab process manager to make sure it only impacts web content processes.
- felipe
- Has some try builds up with the beginnings of the Photon tab animations
- Still very much a WIP, but it’s great to see tab animations come off of the main thread!
- Here’s a GIF. Unfortunately, the GIF is running at 30fps and doesn’t do the smoothness justice.
- Has some try builds up with the beginnings of the Photon tab animations
- Gijs
- Made Windows Taskbar preview code do less work when restoring a large session
- Slogging through the work to make our <browser>’s not load useless about:blank pages when we know they’re going to go somewhere else.
- mconley
- Working with dao to find the best way to avoid doing layout flushes when calculating how to display our tabs in the titlebar
- Re-enabled / renewed a bunch of perf-related Telemetry probes that were about to expire
- Working on renewing a bunch of other perf-related Telemetry probes as well.
Policy Engine
- No updates this week.
Privacy/Security
- We released two blog posts that outline our product and platform strategy against trackers and other annoyances:
- Changing Our Approach to Anti-tracking
- Why we need better tracking protection
- Also worth reading: An (unofficial) blog post on the matter by Ehsan: On leveling the playing field and online tracking
- Shipping Shield Studies for FastBlock and Cookie Restrictions
- Vinoth is working on removing all usage of eval() with system privileges.
- Firefox Monitor shipped as a system add-on to 62.0 en_US users. Testing - pref’d on for 0.5% via Normandy.
Address Bar & Search
- Gijs changed url canonization to make it more coherent across browsers and platforms. CTRL+enter is now used to canonize words to urls, it’s no more possible to canonize to .net or .org, but the suffix can be controlled with “browser.fixup.alternate.suffix”. A new pref “browser.urlbar.ctrlCanonizesURLs” allows to use ctrl to open in a new tab instead.
- Fixed a regression where unvisited bookmarks were not autofilled anymore after a Clear History.
- Improved the highlight on Top Sites Search Shortcuts to be applied more consistently
- Fixed a few url overflow and cursor issues after recent changes to the overflow behavior
- Firefox now accepts both "application/json" and "application/x-suggestions+json" as MIME types for OpenSearch Suggestions
- Fixed a regression where locale specific Search Engines could re-appear after being hidden by the user
Places
- Removed some more legacy code
- Fixed a bug where sites with bogus (empty) favicon <link>s would not get a favicon
Test Pilot

- Screenshots: bootstrap removal patch is under review (on github)
- Thanks to :aswan for moving the enable/disable pref observer code to nsBrowserGlue (bug 1488971)

This week I learned
- [mkaply] You can set MOZ_BUILD_DATE in the environment to override the build ID if you want to build something that matches a released build. This is handy because various databases reset based on build ID, so you move profiles from a released build to a debug build
- [mkaply] If you need to know if Firefox is shutting down, use Services.startup.shuttingDown
