Project Updates
Add-ons / Web Extensions
Somebody will be present to read this out loud if you’re lucky, otherwise enjoy a short list of some highlights:
- Tomislav fixed cookies being unavailable in the downloads API as well as a swath of tests that were “fixed” by another patch. Please do not disable default functionality (e.g. via pref modifications to fix a test) without review from the extension team.
- The topSites API received some updates (1568617 and 1570492) and was moved out of toolkit into browser (due to the set of browser dependencies required, and the fact it didn’t work on mobile anyway). Thanks Drew.
- Ryan Alderete fixed a discrepancy between Chrome and Firefox for setting some WebRTC settings (which should fix uBlock “Prevent WebRTC leaking” option in Firefox).
- Rob Wu fixed the use of chrome/resource urls for search icons (which broke browser.search.get) in some distributions. He also fixed a theme issue and a tabs.create problem.
- Mandy Cheang landed a patch delaying our reading of extension settings on startup \o/
- Shane mostly stared at other people's code and moved a couple patches closer to landing. Because staring at other people’s code is such a high, and admittedly because of the first bullet, he’s also now watching all patches touching extension code.
- nobody@mozilla.org closed some old meta bugs :-)

Developer Tools
Debugger integrated tighter with platform to improve how it gets sources for files
With HTML parser to fix a set of long-standing issues around breakpoints in inline scripts
Improved integration with BFCache to load the right sources after navigating
- Async step over is now done with JavaScript engine support, making it more reliable
- Sources are now correctly showing their blackboxed state in the sources tree, thanks to :chujunlu
- Console’s new multiline editor mode, which lets you iterate on longer scripts with ease, is now enabled by default on Nightly (screenshot)

Multiline editor mode in Console input for quickly switching between modes. - In an effort to make Responsive Design Mode (RDM) work more reliably across web platform features, title tooltips got fixed to work as expected.
- First testable version of full-text Network search landed behind a pref (devtools.netmonitor.features.search) in, done by :lloanalas

New network search panel that breaks down detailed search results - Disabled breakpoints are now correctly registered when DevTools opens
- Inline variable preview for Debugger landed in Nightly behind a pref (devtools.debugger.features.inline-preview), amazing work by :dhyey35.

Fission
- New chart of frontend fission work to be done.
- Various issues found with Responsive Design Mode, such as 1569570 for select elements. Abdoulaye and MikeR worked on some fixes. More to come.

- Some back end tools to help with how we manage story delivery.
- Working on promo content for 70 (paid and non paid)
- Did some changes to re-scope for 70.
Did some more performance recordings on newtab startup, and have some potential performance gains
Possible 200ms startup improvement by rendering below the fold html lazily: https://docs.google.com/document/d/1VsvhJ3eLcRhpOYLb7AR9S58QIjD7jK3ZvpPOH5nOzoQ/edit
Possible 10-50ms startup improvement with lazy load some jsms

Screenshot of about:logins showing favicons, the FxA username and photo, sort by breached websites, breached login icons, and a banner on the selected login explaining that it was breached (link)Security review and testing complete
Add 'sign in to sync' button and message at the top of about:logins
Master password prompt before copying/revealing passwords in about:logins
Improved filtering performance
Many a11y and visual polish fixes
-
Security review complete
Many save doorhanger improvements
Edits to generated password fields will now propagate to storage and other fields it is filled into.
Other polish/tweaks
Main remaining bug to land is to merge an old login and an auto-saved one in the save doorhanger
Performance
- (A bit of PTO these last few weeks, so less progress than usual, but dthayer is back from parental leave now!)
aswan has a patch up to make Monitor a standard browser component rather than a System Add-on. This is part of a test to see how much our System Add-ons infrastructure impacts start times.
aswan is also looking to do the same thing with Firefox Screenshots
- mcheang made it so that we get the country code from nsISystemInfo lazily and off of the main thread
- mcheang made it so that Activity Stream code loads JSMs less eagerly
- mcheang moved reading some WebExtension settings JSON files further out of the start-up path
Performance Tools
- Added tracking for JS allocations. It's still experimental but you can enable it by checking "JS Allocations" in recording panel feature flags(Example profile: https://perfht.ml/301avXy)

(Check the “Javascript Allocations” instead of “Timing” here to see them https://i.imgur.com/uL708vt.png)
- Native allocations tracking is on the way!
- Added PIDs in track context menu. It's now easier to see and enable which process you want to open.
