Remove or Block Cookies Easily in Firefox

Do you want an easy way to deal with all the cookies in your browser? See how quick and simple it can be with the CookieKiller extension for Firefox.

Accessing CookieKiller

Once you have installed the extension there are two ways to access CookieKiller. The first is through the “Status Bar Icon”…here you can see the small “Right Click Menu”…

If you left click on the “Status Bar Icon” you will see a current list of the cookies for your browser. Clicking on any particular cookie listing will remove that cookie from your browser. Notice the three commands at the top…

The second way to access CookieKiller is through the “Context Menu”. As with the “Status Bar Icon” you are presented with an identical current cookie list.

CookieKiller in Action

For our example we decided to use the “Status Bar Icon” to delete cookies. By clicking on the “google.com.sg” listing we were also able to delete the “sub-cookie” (indented listing).

Reopening the list shows both entries are gone.

Doing a refresh of our example page added the cookies back for our next test. This time we decided to eliminate all the cookies at once by clicking on the “Kill All Cookies” listing…

If you have the “Cookie Block Feature” enabled you will see a “dotted square outline” around the “Status Bar Icon”.

    nothing’s easier than just setting FF to block 3rd party cookies. It pre-much gets rid of most bad cookies

    216, I disagree. I couldn’t even find an option in v3.6 to block third-party cookies. I had a slew of tracking cookies Firefox refused to delete. Nor in 3.55. I dropped back to 2.2, which I am using now; it does a decent job of allowing cookie control. But w/ this add-on (thanks, Geek!!) I may be able to go back to the beta, which was a nice browser but for the cookie problem

    Correction, bad memory. There is that option in 3.6.It just doesn’t work.Re-installed 3.6 & same exact problem: 20 or so tracking cookies Firefox can’t or won’t delete (they immediately pop back), & this add-on is completely ineffective; does nothing. Back to version 2.2, & Iron.

    Why am I not surprised that, once again, Firefox has broken something that once worked as it was intended? It’s become common practice with the crap Mozilla is kicking out the door these days.

    As to Cookie Killer, if it would work, it would be a nice add on. Since I’m already sick and tired of Firefox’s habit of crashing for no damn reason I’ve started using Iron, I echo the statement of Mike J, “Back to…Iron”.

    I agree that Firefox team work is not so great these days. Includig it starts to be slow to start for unknown reasons and the team don’t even bother to react to thousands of complain on their own site. I had difficulties to understand how to block cookies in version 3.6. I just don’t want to switch to another browser because I don’t trust MS or Google for developping a fair application in this area.

    Finally reagarding blocking cookies, there is an option for that in FF : under Tools-Options and then selecting “Use custom settings for History”. The related Firefox help page can be found by searching “Disabling+third+party+cookies” in Google.

    There is a good stand-alone Firefox cookie manager called “Cookie Monster.” The latest version is 3.47. What’s nice about it is that you can segregate cookies you need to keep, (i.e., for websites that need to identify you) while deleting those that are unnecessary. “Cookie Monster” has a command that allows it to run without opening the program so that you can delete unwanted cookies anytime — a separate icon is created for this when it installs. You can put this special icon in the Windows startup folder so that every time Windows starts unnecessary cookies are deleted. It can also be put in the Quick Launch area so that you can delete cookies manually anytime you want.

    Highly recommended.
