GOOD QUESTIONS

Let’s clear
a few things up.

Still curious about something?

We’re here to help
What is EditThisCookie v3?

A Chrome cookie manager for viewing and changing website cookies, with editing, search, import, export, protection and blocking tools.

How do I install the extension?

Open the official Chrome Web Store listing in desktop Chrome, choose Add to Chrome and review the permissions. Pin it from Chrome’s Extensions menu.

Are these screenshots of the real extension?

Yes. They were captured from the supplied v3.0.5 extension running in Chromium with sample cookies on cookie-demo.test. The website itself does not read or edit your browser’s cookies.

Can I import and export cookies?

Yes. The reviewed build imports and exports JSON, Netscape HTTP Cookie File, semicolon-separated name=value pairs and Perl::LWP. Import detects the format from pasted text or a selected JSON/TXT file. For exports, choose Download or Copy to clipboard in Options. Keep files private: they can contain session information. See the import and export guide.

Can I use a dark theme?

Yes. In the extension, open Options → Theme and choose Light, Dark or Follow system. Follow system is the default in the reviewed build. Reopen the popup after changing the setting. See the appearance guide.

What permissions and data use should I review?

The extension requests cookie and tab access across websites. The reviewed v3.0.5 build also reports browsing activity, including page URLs and a generated identifier, to an analytics endpoint. Read the extension data-use details and the store disclosures before installing.

Why does a deleted cookie come back?

The site may set it again on its next request, or an extension protection rule may restore it. A cookie with the same name can also exist under another domain or path. Check its scope and the Protected cookies list.

Will deleting cookies sign me out?

It can. Removing a session cookie may sign you out; removing a preference cookie may reset settings. Change one cookie at a time when troubleshooting.
