If you are on a site that normally sets cookies but the cookie dialog is blank, you may be in a private browsing window.

Starting in Firefox 19, the cookie dialogs stopped showing private session cookies. (Old thread: Cannot see session cookies in Private Browsing mode - see only normal cookies.)

I can't recall whether anyone found another way to view them, other than the arduous method of using the Web Console. (Arduous because you have to open the Web Console before loading the page, or reload the page after opening the console, and then click the URLs requested to see what cookies were sent to each of the different servers that contribute content to the page.)

Use the private window rarely. The cookie dialogue box has been completely empty for about two weeks now. As I mentioned, the apparent lack of cookie setting has not affected browsers ability to browse at all. It,s just been a puzzle to me to where the cookies are going. But, thanks much.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookies files like cookies.sqlite-journal in the Firefox profile folder in case the file cookies.sqlite got corrupted.

You can inspect and manage the permissions for all domains on the about:permissions page or for the domain in the currently selected tab via these steps:

• Click the "Site Identity Button" (globe/padlock) on the location bar
• Click "More Information" to open Page Info
• Go to the Permissions tab
• Tools > Page Info > Permissions

Hi cor-el

Problem solved w/safe mode start up. Two extension disabled, themes set to default mode. Normal start-up cookie dialogue box now has one cookie only visible w/scroll up/down buttons which don't move anything. I believe that coookie is probably the last one set. The last theme default update was Dec. 12 which was about the time the problem started. I'll keep trying. Thanks vm for tips/suggestions.
