Quick Sorted Download од Juho Heikkinen

This extension adds a "Quick Sorted Download" item to context menu for links and media files. Clicking it saves the file to a folder which is automatically chosen based on configurable rules, always bypassing the save as dialog.

Rules
A rule consists of a regular expression ("Pattern") that's matched against the object URL, and a folder name. The folder must reside inside your Downloads directory. For example, if your downloads directory is Downloads/, and you want to save files whose URL contains the word 'example' to Downloads/example/, you could add a rule with pattern "example" and subfolder "example/".

If the URL matches none of the rules, the file is saved to the root of your downloads directory.

Limitations

• Files can only be saved inside Firefox's default downloads directory (including subfolders). This is because of WebExtensions API limitations.
  
• Only works for files to which there's a direct link (href or src) to download them with a GET request.
