what is "storage" folder's purpose?

[T]

Hi All,

ff 50.0.2 x64
w7-sp1 pro x64

I was trying to backup up w7 machine's mozilla
directory on appdata/remote to an ftp site.

Whilst trying to rotate the backups, I notices
that the "storage" directory on the backup
would no delete.

It transpired that several of the subdirectories
had names with three plus signs in it ("+++").
Windows burped. (I had to use Linux to delete them.)

I deleted the "storage" directory and problem solved.
What was the purpose of the "storage" directory anyway?

Many thanks,
-T

If you look in those directories you may find some 'idb'
directories. They contain data stored locally by
websites:

I have loads of stuff in there. If you don't you've perhaps
disabled or cleared it.

So-called supercookies.

No, that's stored in webappstore.sqlitein the profile. That's

'Supercookies' often referred to 'Flash LSOs' (local stored
objects) which was an earlier method of storing local
data.

Is there a difference? Supercookies are DOM Storage.
That seems to be the same thing you're calling HTML5
Storage. The link above refers to "web storage" but
shows samples of DOM, using properties of the window
object.

Flash local storage is a different thing, stored by Flash in
the Macromedia folder. This sounds like it might be a matter
of terminology. I'm thinking of supercookies as any local
storage usable by websites. Flash storage is a hack but
amounts to the same thing.

I've learned something from
this, though. I don't have a Storage folder and don't have
any content in webappsstore.sqlite. I thought I was blocking
any storage by setting cache to 0. But I just came across
an option in about:config. dom.storage.enabled
There's also a setting for how much storage to allow.
While I've never had any local storage I had dom.storage.enabled
set to True without knowing it.
