How to display entire stored site data?
Hi there,
Options -> Privacy&Security -> SiteData -> Settings tells me that some sites have several MB of storage on disk. For example, www.facebook.com shows up with a whopping 3.7 MB.
So, I want to check the contents of that storage.
I navigate to www.facebook.com and check WebDeveloper -> StorageInspector. Here I find a meager 1 line session cookie of at most 2 KB, nothing else. No cache, no localStorage, no IndexedDB, no nothing. (I do not use Facebook).
What explains this tremendous difference in "SiteData" and data reported by StorageInspector ?
How can I have a look at the "SiteData" of Facebook ?
Yes, I tried several times, tried a reload of the Options > ... > Settings, restarted Firefox after deleting all the data I see in StorageInspector etc. I still get a difference of some several MB in data which is shown under SiteData and not shown under StorageInspector !
I am a bit paranoid here, since it looks to me that the browser knows something but refuses to show me...

Good question. Not enough info on this in ver 57+ as have my own questions also. If I had the info would provide. If never go to Facebook then it was added by a website that you visit that has facebook in their code. Since do not have send information to Mozilla turned on within Firefox I do not know what Extensions you are using . Can use adblocker to stop some of these cookies like Ublock Origin
- https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/ and scripts in pages with that can do that.

Please let us know if this solved your issue or if need further assistance.
I'm baffled by this dialog. It shows my own website, which stores a couple dozen bytes in local storage, is using 3.6MB. (Screenshot attached.) I can't figure out what that represents, and I should know!
@Pkshadow: No, it does not solve my problem. I do not want to block cookies, but I want to understand, why the browser is giving me (what to me seems like) inconsistent information. Either the routine adding up the amount of side data is wrong or the storage inspector is hiding something from me (or my understanding of addition is different than than the understanding of the browser).
@jscher2000: EXACTLY. Something is not as it used to be - and since it is connected with locally stored data, we should be worried. If the browser reports incorrectly here this means we cannot do proper site forensics. One guess could be that it is the (sqlite ?) overhead of the localStorage implementation ?!?
Maybe it builds up if you keep saving new data and aren't removing old data or the storage key is no longer valid.
If you open the website in a tab then you should be able to use the Storage Inspector.
I figured out what causes my own site to use 3.6MB, it's the sql.js library used in this page:
https://www.jeffersonscher.com/res/stylishextract.html
That library ends up here:
[profile folder]\storage\temporary\https+++www.jeffersonscher.com\asmjs
Apparently this kind of storage is not shown in the Storage Inspector.
Possibly this "information gap" affects other asm.js scripts, but I haven't looked into it.

Yes, same thing that happens to me. You can "Remove Selected" in the dialog and click Save Changes to flush my site data.
Alternately, you can open your profile folder, double-click into storage, then double-click into temporary, then right-click > Delete the https+++www.jeffersonscher.com folder. When you reload the Options page and check again, the data usage will be greatly reduced after that.

That was the first thing I did after I took the screenshot .......
