Most web browsers are configured to accept first and third party cookies by default. They will also honor the expiration dates set by the servers and websites that set the cookies in first place which means that cookies may very well be available on the system for days, weeks and sometimes even longer than that.
While you can take care of cookies manually, either by configuring browsers like Chrome to delete cookies on exit, by removing cookies manually, or by running third party software like CCleaner to do just that, you may prefer more control and automation over the process.
Tab Cookies for Chrome
And that is exactly what Tab Cookies for the Google Chrome web browser brings to the table. To sum it up in a single sentence: it keeps cookies alive for as long as you are on the site that set the cookie. Once you close the tab, all cookies set by websites that you opened in it are removed from the browser.
This does not happen when you keep the tab open, even if you navigate away from the site to another unrelated website.
While that functionality proves useful to remove cookies automatically from your system, it may cause problems on websites and services that you need to sign in to. Cookies are often used for authorization, and removing that cookie means that you will have to sign in again next time you visit the site or service.
There is a solution for that as well. The Chrome extension displays an icon in Chrome's address bar next to the bookmarks icon there. All cookies that the website or service sets are protected when you left-click on it, so that session cookies are kept even if the tab gets closed.
Just left-click again at any time to revert that so that cookies will get deleted once again when you close the tab in the browser.
If you want more control over cookies, automated control that is, then Tab Cookies may provide you with just that. If there is something to criticize, it is the all or nothing approach that gives you no control over sites that set multiple cookies on your system.
Blocking third party cookies is probably sufficient for most computer users as it takes care of the majority of tracking cookies on your system. If you need more control, give Tab Cookies a try if you are using Google Chrome.
