These Weeks in Firefox: Issue 116

Highlights

  • ESMification is a project to move away from our custom JS module system (JSMs) to the standard ES Module system most are familiar with when writing JavaScript.

  • A prototype of loading ESM modules has landed in bug 1432901. We are looking for feedback. Please get in touch with yulia (@yulia on matrix, yulia@mozilla.com) if you would like to discuss any of the above.

  • Picture-in-Picture subtitles support has been added for SonyLiv and Dailymotion

  • Picture-in-Picture now supports forward/backward seeking with the left/right arrow keys on Netflix

  • The address bar used to not convert negative temperatures. Now it does! If you type in -30C to F, it converts it to -22 F. This feature is only available with browser.urlbar.unitConversion.enabled set to true.

Search and Navigation

  • [daisuke] fixed Bug 1457149 on Win64 where Ctrl-L Delete / CTRL-L Backspace does not  clear the address bar when done extremely fast.

  • James [:jteow] fixed a  Bug 1560676  where autofill was broken for URLs such as localhost:8888/foo.

  • [daisuke] and Drew [:adw] have been working on autofill so that it fills urls not only origins. Bug 1597791

  • [daisuke] fixed Bug 1633924 where adaptive results were case sensitive. This was changed so it’s case insensitive. If you typed FIRE or fire the url https://www.reddit.com/r/firefox/ will be shown in results

  • Mandy [:mcheang] Fixed Bug 1673868 where DDG Ads on Search Result Pages was reported inconsistently.

  • Mandy [:mcheang] Did some work for Bug 1759207 to show an infobar for when an application default search engine is removed from configuration.

  • [daisuke] fixed Bug 1761154  where the address bar does not convert negative temperatures. Now it does. If you type in -30C to F, it converts it to -22 F. This feature is only available with browser.urlbar.unitConversion.enabled set to true.

  • Drew [:adw] on Bug 1765595 added a Nimbus variable to load Fx Suggest suggestions with a different type on Remote settings.

  • Mark [:standard8] removed osfile.jsm usage from search because of new linting rules for Bug 1769047 .

Screenshots

  • [niklas] I landed the initial patch for the draggable overlay. Set `screenshots.browser.component.enabled` to true to test out the new screenshots component!

 

ESMification status

  • ESMification is a project to move away from our custom JS module system (JSMs) to the standard ES Module system most are familiar with when writing JavaScript.

  • A prototype of loading ESM modules has landed in bug 1432901, it is now possible to load modules synchronously for system code (in progress example for a content/system component).

  • The team is working on a lazy module API similar to defineLazyModuleGetters & co.

  • There are a couple of questions around the API and naming that are currently being explored.

  • We are looking at a migration in H2.

  • We are looking for feedback. Please get in touch with yulia (@yulia on matrix, yulia@mozilla.com) if you would like to discuss any of the above.
