Both the download and cookie exception dialogs are empty. I know there are entries there but I can't see them. This has been a problem since release 5.0 on Mac OSX.
They're empty, no entries. When I download a file I can see the download progress but once the download is finished the entry disappears.
The Cookie Exceptions list is always empty. But I know the list contains entries because I have Firefox configured to ask me about allowing cookies. So there should be many entries with sites either allowed, allowed for session, or denied.

The file "permissions.sqlite" stores 'allow' and 'block' exceptions for cookies, images, pop-up windows, and extensions (software) installation.
You can try to delete that file in case there is a problem with it.
You can also try:
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

Remember Download History - that worked.
Had to delete my "permissions.sqlite" file.
I had the same issue: Exception list empty, but exceptions still present. I've inspected my permissions.sqlite file and found an entry with permission set to -1. After changing this to 1, all exceptions were visible again.
Interesting. Can you give an example so I can find an example. Sometimes the files are completely blank.
