Capturing pdf from ftp produces an error

[i3v]

Capturing a pdf file (either drag&drop the tab or via the main menu) from an ftp server e.g. this: ftp://iristor.vub.ac.be/patio/SURF/pub/DATAtransit%20SURF-INTERNVUB/oscars/Oxford/X-MaxN%20SEM%20DataSheet.pdf produces issues (Waterfox 56.2.8 (64-bit)):

1. If I try to open the saved item I get urn:scrapbook-download-error:ftp://iristor.vub.ac.be/patio/SURF/pub/DATAtransit%20SURF-INTERNVUB/oscars/Oxford/X-MaxN%20SEM%20DataSheet.pdf url and the following error message from Waterfox:

The address wasn’t understood

Waterfox doesn’t know how to open this address, because one of the following protocols (urn) isn’t associated with any program or is not allowed in this context.`

2. If I try to search through my collection, the search hangs on this item:

This is somehow a regression compared with ScrapBook by Gomita as we added further support for HTTP header handling. We are unlikely to fix this since it involves massive code reworking and the use of FTP in the browser is rather narrow and discouraged. You can download the file via FTP, drag it to the tree, and modify the source URL afterwards instead.

@danny0838 ,
Thanks for your reply! Yep, I can leave without ftp support. But, IMHO, the most scary part of the issue is that a fake (misleading) & broken item is created (which, in turn, breaks the search thing)... No easy way to fix this either?

Legacy ScrapBook does not implement a verification and thus saving any invalid page, such as the about:addon page, creates a "fake" item without noticeable warning, too. It is undoubtedly a bad behavior and technically fixable but by no means a small job. We might consider working on it someday.
