DevTools

DevTools Toolbox

• Abhijeet Chawla updated some of our code to avoid using deprecated React lifecycle methods (#1810462, #1810437)

• Jeff Muizelaar added profiler markers for debugger log points (#1928514)

• Alexandre Poirot added the ability to record console API calls and DOM Mutations when tracing to the profiler (#1929007, #1929004)

• Alexandre Poirot made it possible to search for traces by function call argument values (#1921020)

• Alexandre Poirot improved webextension debugging by automatically switching to the expected document on hover when inspecting webextension UI (e.g. sidebar, popup, …) (#1754452)
• Nicolas Chevobbe is still working on adding support for High Contrast Mode in the most used panels (#1916391, #1926878, #1917782, #1926794), #1926851, #1926852, #1916698, #1920711, #1927063, #1926983, #1916650, #1916656, #1921758, #1916682, #1916693, #1916721, #1928108, #1916722, #1916660, #1929200, #1929594, #1916669, #1929508, #1930099)
• Hubert Boma Manilla fixed the “Go to line” palette + Cmd/Ctrl+B to add a breakpoint on the line the user jumped to (#1925974)

Lint, Docs and Workflow

• A change to the mozilla/reject-addtask-only has just landed on Autoland.
  • This makes it so that when the rule is raising an issue with .only() in tests, only the .only() is highlighted, not the whole test:

• This should make it easier to develop tests whilst using .only().
• The ESLint curly rule has now been re-enabled, after it was accidentally disabled.

Migration Improvements

• mconley landed a patch that makes it so that automatic backups don’t get regenerated if a cookie expires “naturally”
• mconley also landed some probes to get a sense of how the backup service is performing in the wild, and what errors it is hitting

New Tab Page

• The team is working on some new section layout and organization variations – specifically, we’re testing whether or not recommended stories should be grouped into various configurable topic sections. Stay tuned!

Picture-in-Picture

• Thanks to contributor kern25 for:
  • Updating our Dailymotion site-specific wrapper (bug), which also happens to fix broken PiP captions (bug).
  • Updating our videojs site-specific wrapper (bug) to recognize multiple cue elements. This fixes PiP captions rendering incorrectly on Windows for some sites.

Search and Navigation

• Scotch Bonnet
  • daisuke changed shift-tab so that after focusing the address bar (e.g. ctrl-L), the dedicated search button is focused.
  • jteow fixed an issue where search mode was transferred to other tabs.
• Address Bar
  • Yazan fixed a regression where favicons could take a while to appear on the address bar.
• Search
  • Moritz has been working on re-enabling support for the search form to OpenSearch engines & adding it to the search configuration. This is accessed by shift-clicking on one of the engines under the dedicated search button, or on the engines in the separate search bar.
  • Moritz has also been working towards improving search engine support for differently sized icons.
  • Standard8 fixed some no-shadow ESLint warnings and test manifest ordering warnings in search code.
