Status: UNCONFIRMED

(Firefox :: Settings UI, enhancement)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151110145223

Steps to reproduce:

In preferences when you select Privacy -> accept cookies -> Keep until


Actual results:

Being presented with selection : 
- Until they expire
(in this case you are agreeing to unlimited tracking, no limits set)
- Until I close firefox
(this sets a way too short lifespan for session cookies)
- ask me any time
(this option makes a lot of visual spam and it is really not a good choice, since most sites now want to set cookies).


Expected results:

To have one more choice - 
- Expire all cookies in <x> days.
So cookies lifetime will be limited for a reasonable limit.
If I set, for example,  this option for 7 days:
- my session cookies will mostly expire in less than this limit.
- Long time tracking and forgotten visited sites that left long lived garbage cookies will be removed after a week.
