How to enable/disable cookies on a page in the Firefox

1. open the page
2. click on the Tools → Page info menu of the Firefox
3. click on the Permissions tab
4. scroll to the Set cookies entry
5. to enable cookie support:
   1. uncheck the Use Default checkbox
   2. select the Allow radio button in the same row
6. to disable cookie support:
   1. uncheck the Use Default checkbox
   2. select the Block radio button in the same row
7. close the Page info window to save changes

P.S. Checking the Use Default checkbox is always blocking cookies for me.
