Customize context menu on RSS feed items? Topic is solved

[Navigator]

Operating system: Linux Mint 22.1
Browser version: PM 33.7.2
32-bit or 64-bit browser?: 64-bit

On the context menu (right click) that appears for items in an RSS feed I have four "Open [in]" commands, "Bookmark This Page" and "Copy." I would like to have a command to directly pass the URL to yt-dlp, or if it is easier via Grabit. Is there an easy way to customize this menu like userChrome, or would a new extension be required?

The context menu is a giant list whose items are hidden when they do not apply. To add a new entry you'd need to insert an item in this list, tell it to show itself only when acting on an RSS fees item, then make it act when you click on the item.
Only way to achieve it is with an extension.

There is no need for yt-dlp (so no need for an add-on) if there is a direct link to the video/audio file. For example, the MP4 file "BigBuckBunny.mp4" can be downloaded with "Right-Click + Save Link As..." on the link below:

https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4

If there is no direct link to the video/audio file (see the example above), then that site must be in the list of "supported sites" displayed here:
