What's new in Firefox 129
Firefox Desktop
Reader View with enhanced Text and layout menu
|
Description:
|
The look and feel of the menus in Desktop Reader View have been updated. New functionality has been added, including the ability to add custom color schemes and additional text formatting options. We want to increase the comfort (and accessibility) of using the reader by making the type controls support all the options in the WCAG success criteria for text spacing, allowing users to pick their preferred fonts and allowing custom colors.

Extending linux install SUMO page with AppArmor profile info for non packaged installations
|
Description:
|
Our sandbox code makes use of unprivileged user namespaces when creating new processes for enforcing more security. This feature can in some context be considered a security risk, thus some distribution started to restrict its usage and only allow it to selected binaries via AppArmor profiles.
