Can I make FF store only on cookie?

[Advice Pro]

I plan to deselect Accept third party cookies because this clogs up my computer, but I just want to keep Gmail's cookie.

Hi to all

1) Go to the Tool menu bar or by pressing "ctrl+shift+delete"
2)then click on clear private data
3) after that you can find a new window to delete cookies.
4) just do right mark in front of cookies and click ok
