Why does a sign in pop up on a bookmarklet not let me sign in?
When I click the Ziplist bookmarklet I installed, it displays a sign in to Ziplist. I sign in; it asks to sign in again, and again, and again. Why? Ziplist bookmark works on Safari. When I contacted Zip list help, they said if it works on Safari, it must be a Firefox problem. They also said their zip bookmark worked on their Firefox. Not sure why it is not working on mine. I operate a Mac 10.8.5

After looking at your screen shot, I think the problem is blocking "third party" cookies. In order to stay logged in with the ZipList site across a number of other sites, the bookmarklet needs to be able to access the ZipList cookie, and this is a third party cookie.
You can change your setting to allow third party cookies in the Preferences dialog.

Do you have this problem on every website or only on some websites?
I don't know whether this is relevant to the sites you are trying to use the bookmarklet on:
When Firefox added a security feature allowing sites to block scripts from other sites, bookmarklets were also blocked on those sites. Hopefully this will get fixed, but for now, you may find that bookmarklets do not work on some sites in Firefox. Background: Bookmarklets don't work on https:// sites.
This can also be a CSP (Content-Security-Policy) issue.

This zip bookmarklet has a sign in pop up every website. I have tried to uninstall/reinstall bookmarklet; I have tried signing in without using autofill. Again it works fine with Safari.
Zip tech support says the bookmarklet works on their Firefox using a Mac. Just can't figure out why it doesn't work on mine : (
I uploaded an image; not sure how much it might help.
