Firefox & Gtk Emoji picker

Summary

After nearly three years of development (it takes time to make up one’s mind) Firefox for Linux users can now enjoy seamless emoji insertion using the native GTK emoji chooser. This long-requested feature, implemented inFirefox 150 (recent Beta), brings a more integrated experience for Linux users who want to add emojis to their web content.

For users who prefer not to use this feature (perhaps due to conflicts with custom keybindings or specific workflows), Firefox provides a preference to disable it. Go to about:config page and set widget.gtk.native-emoji-dialog to false. Why it took too long? The native GTK emoji picker implementation uses the GtkEmojiChooser popover built into GTK3. Unlike other GTK dialogs (file picker, print dialog), it can’t be invoked directly in GTK3 – it must be triggered by a key-binding event or signal on GtkEntry or GtkTextView widgets, and the widget has to be visible from GTK’s perspective. This conflicts with Firefox’s GTK architecture, which doesn’t use GTK widgets directly but instead paints everything itself. But a solution was found. Firefox already has an invisible GtkEntry widget that’s not attached to a...
