Cookies or metadata saved across sessions
I have FF 49b7. I have noticed that whenever I start FF a folder shows up in my profile called "Storage". I have also noticed that when I go to www.theguardian.com that cookies or some kind of metadata gets deposited in this folder. This is in spite of the fact that I explicitly block this site from setting cookies in the options / privacy / exceptions setting and I set the option to delete all settings upon close of FF. I discovered this by running CCleaner and noticing that FF still showed cookies or at least something present. I opened probably another 100 sites and monitored what they did - no issues. Not sure what is going on but I'm bothered that FF does not clear or delete this folder. I have deleted this folder and reopened FF and the folder is recreated - empty to start with. Until I visit this one web site. I have attached a log from CCleaner below.

Re: Cookies or metadata saved across sessions
it's "dom-storage".. you can disable "dom-storage" but doing that could cause problems with some websites, so disabling it is not recommended..
i had problems with "google-drive" when "dom-storage" was disabled so i leave it enabled..
"twitter.com" uses dom-storage.. i don't know if disabling dom-storage would cause problems with using the "twitter.com" website or not..
in FF's "about:config", the setting for dom-storage is "dom.storage.enabled"..
i went to the "theguardian.com" website, just now, and i am not seeing that it is using any dom-storage..not on my computer..

Re: Cookies or metadata saved across sessions
Ccleaner is not a recommended option on these forums. It has often been reported to cause problems by deleting elements of Firefox that are necessary for proper operation.

Re: Cookies or metadata saved across sessions
Nope, it's IndexedDB. localStorage goes inside the "webappsstore.sqlite" file.redwolfe_98 wrote:it's "dom-storage"
You can disable by setting about:config > dom.indexedDB.enabled to false
It's not as widely used as localStorage, so I'd say if this really concerns you then you can try disabling it, but make sure to remember you disabled IndexedDB in case of site breakage.

i don't really follow that.. i just saw that the "storage" folder was being used so i thought it was "dom-storage".. (i have always thought of the content in the "storage" folder as "dom-storage" )..barbaz wrote:Nope, it's IndexedDB. localStorage goes inside the "webappsstore.sqlite" file

in my experience, setting "dom.indexedDB.enabled" to "false" caused problems with the "intel.com" and "c-span.org" websites (so i don't disable it)..

Re: Cookies or metadata saved across sessions
The phrase "DOM storage" is confusing, to me.. why Mozilla put IndexedDB in a folder called "storage" I don't know, so if you need help following that, maybe ask them?redwolfe_98 wrote:i don't really follow that.. i just saw that the "storage" folder was being used so i thought it was "dom-storage"..

Don't misquote me ever again. I choose my wording carefully and wrote the statement the way I wrote it for a reason.redwolfe_98 wrote:barbaz wrote:in FF's "about:config", you can disable "dom.indexedDB.enabled" by setting it to "false"
You can disable by setting about:config > dom.indexedDB.enabled to false
Please fix it in your post, thanks.

Re: Cookies or metadata saved across sessions
I disabled it. The storage folder is still created but nothing is stored. Haven't done a lot of browsing to see if I am impacted. Interesting. Thanks.

Re: Cookies or metadata saved across sessions
Rats. I spoke too quickly. The situation is still there. Out of all the web sites I visit this is the only one that exhibits this behavior. Why would they do this and what does it do?

Re: Cookies or metadata saved across sessions
For whatever it is worth I went into umatrix and blocked scripts from assets.guim.co.uk

Re: Cookies or metadata saved across sessions
go back and check your settings for cookies.. maybe you have the "theguardian.com" cookies set to "allow" rather than having them set to "block".. if you have them set to "allow", that could be the difference..share666 wrote:The situation is still there
the only time that i see the same thing that you are seeing, in the "storage" folder, is after having visited "twitter.com", and i have cookies for "twitter.com" set to "allow"..
incidentally, to block the "theguardian.com" cookies, you need to use "https://www.theguardian.com" in the cookie-settings, not "http://www.theguardian.com".. note that one is for a secure-connection while the other isn't.. at least i assume that is the way that it works since you have to use similar settings for "allow-ed" cookies..
however, it might be best to not have any custom-settings for the "theguardian.com" cookies: it is possible that blocking cookies there could cause problems with the website..
on my computer, i have FF set to allow first-party cookies and to block third-party cookies, and i use some custom-settings for a few cookies that i want to be saved, setting them to "allow"..
i already said that i ran into some problems with some websites after disabling "dom.indexedDB.enabled".. my advice is to not disable it.. if you leave it disabled and then find that you have problems with some websites, you will need to restore the default setting for it, which is "true", or else create a new FF-profile, to resolve the problem, if you can't figure out which tweaked settings are causing problems..
here is a webpage with information about how to "refresh" FF (to create a new FF profile), in case you can't remember to re-enable "dom.indexedDB.enabled" after finding that FF doesn't function properly on some websites when it is disabled:
https://support.mozilla.org/en-US/kb/re ... sh-firefox
imo, you should unblock scripting for "assets.guim.co.uk" if you want the "theguardian.com" website to function properly.. "assets.guim.co.uk" is a legitimate domain that belongs to "guardian news" and is used for delivering some of the content for the "theguardian.com" webpages..share666 wrote:I went into umatrix and blocked scripts from assets.guim.co.uk
again, if you find that the "theguardian.com" website is not functioning properly, try unblocking scripting for "assets.guim.co.uk".. you might need to re-enable "dom.indexedDB.enabled", too..
if you can't get anything to work, refer back to the link, above, for "refreshing" firefox, which will restore the default settings..

Re: Cookies or metadata saved across sessions
No need to use a jackhammer to put a push-pin. Creating a new profile for troubleshooting purposes is best done while leaving the old profile in place, by starting Firefox with the -profilemanager command-line flag.redwolfe_98 wrote:here is a webpage with information about how to "refresh" FF (to create a new FF profile), in case you can't remember to re-enable "dom.indexedDB.enabled" after finding that FF doesn't function properly on some websites when it is disabled:

Re: Cookies or metadata saved across sessions
I have been using a clean profile. And I reset dom.indexedDB.enabled. My experience with the website after blocking "assets.guim.co.uk" has been fine. I am still able to read content. I still don't know why or what information is being stored on my PC. Until I have a better handle on it I intend to keep it blocked. I've asked the Guardian but I have not received a reply and probably won't. I wonder if they do the same thing in the EU. This is more idle curiosity than any paranoia. I have free time after retiring and I like to go down rabbit trails just the see where they lead.
