<< Why it doesn't use stored credentials just like Sync does? >>

If you sign into Pocket with your Firefox Sync account, this is the behavior.

It should only prompt you to re-login if you've cleared cookies. Even then, you can re-login via FF Sync without entering the password in again.

If you're logging in with a service other than FF Sync (ex: Google), I'm not sure how you expect FF to know what your credentials are to log you in.

Looks like Cookie AutoDelete extension somehow affects Pocket but not Sync. Thank you for hint!

Yes, I had to whitelist '*.getpocket.com' to avoid auto deletion of Pocket cookies.
