New features and improvements in Firefox 101.0

Return of the classic download prompt

The big new improvement in Firefox 101 is the one not highlighted in the official release notes. Mozilla changed the browser’s download behavior in Firefox version 97, which it released in January 2022.

Firefox displayed a prompt to the user, giving them options to open or save the file. The new download prompt copied the behavior of Chromium-based browsers; this meant that Firefox started downloading immediately.

Although there was an option to change the behavior by enabling “always ask you where to save files” in the preferences, this did not replicate the full functionality of the classic download prompt.

Now with Firefox 101 comes an option to restore the old prompt:

  1. Load about:preferences in the Firefox address bar.
  2. Scroll down to the Applications group on the page.
  3. Switch the default “save files” option to “ask whether to open or save files” on the page.

Other Changes

  • Mozilla notes that Firefox users can assign custom actions to any “unconfigured MIME type” after the download is complete.
  • Firefox supports the use of multiple microphones during video conferences. The browser supports switching between microphones, provided the conferencing service provider supports the feature.
  • Firefox for Android supports using a magnifier for forms on Android 9 and later, which improves the usability of forms in the browser.

Developer Changes

  • Sites can use the prefer-contrast media query to determine if a user has requested higher or lower contrast.
  • Small, large and dynamic window sizes have been introduced
  • Constructable style sheets are now supported.
  • AV1 codec settings are now parsed correctly in media support queries.
  • The WebDriver BiDi protocol is enabled by default in this version of Firefox
  • Several Manifest V3 APIs and changes added:
    • Added scripting API for add-on developers, “which provides functionality to run a script, insert and remove CSS, and manage the registration of content scripts”.
    • Added action API, “which carries over the functionality of the browserAction API in the Manifest V3 extensions”.
    • Added “host_permissions” manifest key, which is available for Manifest V3 extensions.
    • The “background” manifest key property “persistent” can be set to false under preference control: for Manifest V2, the extensions.eventPages.enabled preference and in Manifest V3, the extensions.manifestV3.enabled preference.
    • The content script execution environment has changed for Manifest V3 extensions.
