Firefox Developer Edition (eo) 138.0 አውርድ

New
- Firefox for Android now supports TLS client authentication certificates. When a TLS server requests authentication from the browser, Firefox can now make use of the client certificates that have been added to your Android device.
- Desktop mode in Firefox for Android is now enabled by default on tablets, but can still be disabled from the Site Settings.
- You can now copy links for background tabs using the tabstrip context menu on MacOS and Linux.
- Firefox on Windows 11 now uses acrylic-style menus for popup windows, which better match the operating system’s aesthetic. Users who wish to customize this behavior can do so via the widget.windows.mica.popups preference.
- Firefox for Android now allows you to share a downloaded file or its original URL from the Downloads screen.

This feature is part of a progressive roll out.
What is a progressive roll out?
Certain new Firefox features are released gradually. This means some users will see the feature before everyone does. This approach helps to get early feedback to catch bugs and improve behavior quickly, meaning more Firefox users overall have a better experience.
- Added support for the import map integrity field. You can now ensure the integrity of dynamically or statically imported modules.
- A new column was added to the Network panel showing the full path of the request URL. This enhancement makes it easier for developers to quickly view and analyze the complete request paths.
Web Platform
- Applications can now set their preferred degradation method to be utilized when encoding the configured frame rate and resolution cannot be maintained. (Learn more)
- Introduced support for Import Attributes, allowing developers to specify additional metadata when importing modules.
- Firefox now enables the cache directive for the Clear-Site-Data header, allowing websites to clear the networking cache. The header gives websites more control over data stored for their users, such as clearing the network cache during logout, mitigating the risk of privacy leaks. (Learn more)
