However, it is already possible to obtain cookies and to generate HTTP requests from a Chrome extension by using content scripts, so these new APIs don’t expose any new vulnerabilities.

As a necessary part of web browsing, HTTP cookies help web developers give you more personal, convenient website visits. Cookies let websites remember you, your website logins, shopping carts and more. … While most cookies are perfectly safe, some can be used to track you without your consent.
Cookies are files created by websites you visit. They make your online experience easier by saving browsing information. With cookies, sites can keep you signed in, remember your site preferences, and give you locally relevant content.
If you are using Chrome you can goto the “Application” tab (within Developer Tools) and find the item “Cookies” in the left sidebar. From there select the domain you are checking the set cookie for and it will give you a list of cookies associated with that domain, along with their expiration date.
Chrome doesn’t support syncing cookies via Chrome Sync. As for extensions, it looks like it should be possible, but can’t find anything on the Web Store or otherwise to do it.
Cookies can be shared with other data storage, through browser extensions. Maybe in Flash or Google Gears you can maintain shared DB between browsers, but it needs to be installed on both of them, of course.
