I have been using the latest version of Firefox with the standard add-ons viz Ublock Origin, Adblock Plus, NoScript and so on. I can put up the exact list if required but every time i close a tab a cookie from ec2-35-169-248-108.compute-1.amazonaws.com get deleted even though there is nothing related to that host name anywhere installed on my computer specially in firefox or its addons.

and being a privacy conscious individual i had already disabled all third party cookies and other enabled all other privacy settings.

Is someone building a profile of each website and webpage that i visit ? how do i resolve this problem ?

Please find images of the specific hosts' cookies being auto deleted by in the right hand button corner highlighted in Red color by "Cookie AutoDelete" which is one of the security addon downloaded from https://addons.mozilla.org

the previous version of firefox was 67.0.3 but then I updated to the latest version of Firefox ie 68.0.1 which has the user agent on Windows 7

"Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0"

also updated all the plugins viz flash to the latest version ie NPSWF64_32_0_0_223.dll

along with the latest version of all the Addons which can be seen in the attached Picture "Addons.jpg"

even with that I can still see notices of the tell me cookies from host name ec2-35-169-248-108.compute-1.amazonaws.com are getting deleted at the closure of every tab.

what is going on ? any help will be appreciated.

thank you in advance.

hi, can you try to press ctrl+shift+j in order to open the browser console, then enable logging of "requests" and "xhr" and see if you can tell this way which exact url on amazonaws.com the browser is connecting to when opening a new tab. also if you could copy the contents of your about:support page, put it into a site like pastebin.com and share it here might be of help...
