With Firefox, how can I get a cache entry as a file using its entry info
I use Firefox 58 on GNU/Linux Mint 18.3
If I visit about:cache?storage=disk&context=, I get a listing of cache entries; and if I click one, I see some meta-data, and then this sort of an octal dump of the contents:
00000000: 1f 8b 08 00 00 00 00 00 04 00 ec bd 69 73 db 48 ............is.H
00000010: b2 28 fa f1 45 dc 5f 41 c1 1a 19 10 c1 55 3b 29 .(..E._A.....U;)
00000020: 90 d7 6d bb a7 1d e3 de 2c f7 f4 99 21 69 0f 08 ..m.....,...!i..

and so on. But - I want the actually cached document/sequence-of-octets, as a file. Can I get that somehow? Through the browser UI or from the command-line based on the cache entry details?

Restore file with HEX data
First, remove the line numbers at the front and the characters at the end.
To do so you could copy the dump data to an editor using one of these:
- a multi-line cursor
search and replace: search with the regular expression:([0-9a-f]{8}:ss)|(.{16}($|n))and replace it to nothing.
Second, insert the pure hex-data you now have into an hex editor like e.g. https://hexed.it/, export / save the file and make sure you give the file the right file-ending, depending on the content-type.

Well, it is but not as a readable file. If you have a look at about:cache?storage=disk&context= you will see a property named: Storage disk location

that regex is incorrect, the line numbers are reported as hex so you need([0-9a-f]{8}:ss)|(.{16}($|n))
