I have the settings in Firefox accordingly. The thing is that Cookie seems to be working sometimes, it displays the cookies from Firefox, but stops refreshing this after a while.
I now had it running and showing updates for new cookies, but after a while it stops and is not refreshing. I can see in the Cookie window from time to time a spinner animation so it seems that Cookie is trying to get new data from Firefox, but it is not showing this new data.

I have been away from Firefox for a while and using Safari as the cookie handling was not working as I thought it would. I now checked again and I still have the problem that Cookie (non-app-store-version) does not see and delete the cookies in Firefox. After clearing the cookies from FF, I visited a couple of sites, there are cookies for these sites stored in the browser as can be seen in the attached screenshot (google, amazon, swettpproductions).
The second screenshot shows the Cookie window: no actual cookies displayed.

Even closing the browser and/or Cookie does not seem to be able to work with removing the cookies - if at least the removing would work and only the display were broken, but even after clicking 'remove' in Cookies, they are still in Firefox.

image upload not working

@SweetP after letting both browser and Cookie running for a couple of hours, Cookie stops displaying the non-favorite cookies, it just shows a handful of favorites.
But there are a lot of cookies showing in the browser. So I do not get the info about these in Cookie and I cannot delete them.

@SweetP no profiles, all in the standard locations. I had the Cookie5 app (App Store version) still in the trash and the Cookie5.dmg in Downloads, I cleaned that up.
Now it looks better, I am seing more cookies and databases now. So it seem to be working after that cleanup.

I have the settings just this way. I deleted the cookies from within FF, shut it down, restarted it and logged in to different sites. No cookies show up in Cookie.
Restarting Cookie doesn't help either.

BTW, every time I start Cookie it tells me I should enable Full Disk Access, which I have done. I am running Cookie 5.9.2 and FF 63.0

not working for me, Cookie 5.9.2 and Firefox 63.0. Cookie displays only favorite cookies, the other ones are not shown. Firefox has a lot of them, but Cookie does not show or delete them. After diabling favorites and reenabling them, no cookies from Firefox are shown at all.

thanks for the info; I just checked when I bought Cookie in the App-Store, that was 4 years ago. After using the software for so long now I think it's fair to support you further, so I just bought the non App-Store version.

Hi,

the App Store show version 5.8.7 as latest, while on your website you list 5.9.1 which has Mojave support. When will this version be available as App Store update?
