Forum der Gemeinschaft Firefox

I've searched the community for support to add bookmarks inside my PDF files using Firefox, but all I get are articles and community posts from two or three years ago.

I currently see no features or buttons to edit the outline of a PDF using Firefox (153.0.4). Are there any Firefox extensions or other Firefox methods that I can use to do this in the meanwhile, or do I have to resort to using third-party software and solutions?

Where can I suggest to add this feature if it doesn't exist?

Thank you for reading.
