High Profile Improvements – These Weeks in Firefox: Issue 176

Highlights

• Multiple profiles are now enabled by default in Nightly!
  • Preffed on in Nightly only – upcoming 0.5% rollout in Beta and Release will be done via Nimbus
  • File bugs against Toolkit :: Startup and Profile System
• For WebExtension authors, failed downloads with a NETWORK_FAILED error can now be resumed through the downloads WebExtensions API – Bug 1694049
  • Thanks to kernp25 for contributing a fix for this longstanding bug 🎉
• Alexandre Poirot has enabled Service Worker debugging by default in the Firefox DevTools debugger
• Moritz fixed a bug where users switching between Fx versions using the same profile were unable to search and saw broken context menus. This affected a small number of users in release, and so his patch landed in a dot release.

DevTools

• Alexandre Poirot worked on several fixes for webextensions debugging:
  • Fixed a regression where webextensions creating iframes would lead to blank devtools (#1941006)
  • Fixed a bug where content scripts could appear duplicated in the source tree, and would also result in awkward behavior when pausing / stepping (#1941681)
  • Improved the handling of messages logged from content scripts to avoid duplicated log entries (#1941418)
  • Show manifest error when reloading an addon from DevTools (#1940079)

    • 

      An error message is certainly better than silently failing in this case.

• Nicolas Chevobbe fixed a few accessibility and High Contrast mode issues:
  • Fixed the color of the close button used in sourcemap warnings to be correct in dark mode (#1942227)
  • Updated the netmonitor status codes to be visible in High Contrast mode (#1940749)
• Nicolas Chevobbe also made several improvements to autocompletes in DevTools:
  • The CSS autocomplete will now provide suggestions for variables when used inside calc, for instance in width: calc(var(– (#1444772)
  • The autocomplete in the inspector search is now handling correctly classnames containing numbers and special characters (#1220387)
• Nicolas Chevobbe addressed a long standing issue in the JSON viewer which would always display values after parsing them via JS, which could result in approximate values for big numbers or high precision decimals. The source is now always displayed, and we also show the JS parsed value next to it when relevant. (#1431808)
  • 
• Julian Descottes fixed a bug with the Debugger local script override which might incorrectly show scripts as being overridden if another DevTools Toolbox previously added an override (#1940998)
• Julian Descottes addressed a regression which would lead to blank devtools if any iframe on the page was showing an XML document with an invalid XSLT (#1934520)
• Julian Descottes fixed an issue with the Debugger pretty printing feature, which could fail if the file contained windows-style line-breaks (#1932023)
• Julian Descottes finalized an old patch to show details about the throttling profiles you can select in the network monitor and RDM (#1770932)

  • 

    In case you need a reminder of what 2G speed is like.

• Hubert Boma Manilla fixed a recent regression with the preview popup in the debugger which would not show the value of the hovered token (#1941269)
• Hubert Boma Manilla improved the edit and resend feature in the netmonitor to properly set the security flags for the resent requests and avoid bugs for instance with requests using CORS (#1883380)

WebDriver BiDi

• Spencer Poor (:speneth) fixed all the linter warnings in Actions.sys.mjs.
• Henrik Skupin fixed an issue when another Firefox instance is using the Remote Agent and hasn’t shut down properly, a new test starting Firefox on the same WebSocket port will trigger a 5-second wait for the port to free up. If it remains unavailable, Firefox will shut down.

Lint, Docs and Workflow

• Gijs enabled the eslint-plugin-promise rule for valid-params which checks for functions on Promise being called with the correct amount of arguments.
  • This will protect against cases such as foo.catch() which looks like it should do something, but doesn’t.
• Standard8 added a linter for checking that we don’t include package names in unpublished package.json files.

New Tab Page

• The New Tab layout update has rolled out to 100% of our US population! We’re aiming to do the rest of the world soon.

  • Daisuke landed a patch so that contextual search works with multiple-word searches (1938040)
  • Moritz fixed a bug where the unified search button icon wasn’t being refreshed correctly in private browsing windows (1938567)
