Developer

  • Developer Information

  • Firefox for Linux changes shortcut key for "Select All" from Alt-a to Ctrl-a for solving web-compat and avoiding conflict with access keys. If you want to keep using Emacs like key bindings, e.g., you configured your GTK settings to use Ctrl-a as a shortcut key for moving caret to beginning of a line, you need to change ui.key.textcontrol.prefer_native_key_bindings_over_builtin_shortcut_key_definitions and ui.key.use_select_all_in_single_line_editor from about:config. These prefs are currently disabled by default but would be enabled by default in a future release.
