@wicknix, or anyone else:
storage 😕
In the
Preferences/Advanced/Network tab,
Offline Web Content and User Data is set to “Always ask” and has been so for ever. I've never, ever been “asked”, not that I ever use the browser offline, and Application cache here always shows 0 bytes used. Ages ago in Firefox, my webmail provider had once abandoned a few Mbs in there (without asking), but then they went away again.
In AF's Profile there's a directory called “
storage”. Inside of it two subdirectories, “
permanent” and “
temporary”, always empty, and a third one named “
default”, which gets filled with more subdirectories in a “
https+++www.abcdefg.xyz” format. These in turn contain more code-like subdirectories, as well as a single 524kb sqlite file. These web addresses directories correspond to sites (often news sites) which have been visited, but should definitely not be leaving anything behind. Of course I never get “asked” either.
I've never figured out what these “
+++site” directories were all about, but I've been deleting them as part of routine maintenance. However… while there came only 4 or 5 of them per month in Firefox, I get about 3-4 times as many in AF.
There's a “
storage” directory in a basic NewMoon profile too, but not in a basic ArcticFox profile. Meaning it could safely be deleted?
