Today, I have a tip about cookie, i think it's a useful if you want to know more about your current visiting website, it's faster and easier, another one good thing, you can use this tip on every browser (Google Chrome, IE, Firefox, Safari, etc..), in this post i assume that you known what cookie is, but i'll give you more details if i have time. For now let try a new trick to view your cookie.

Cookies are use to store your data in your computer, it make the web server know you if you used to visit that site, you will can access some website that require user/password without filling out your user and password if you enable to use cookie on browser, due to what is cookie is not important part in this post i don't want to make this post too long and make you bored so i'll give a short details just this.

Every browsers have a way to view or show cookies that store on computer but it depend on what client's browser you use, i mean differ browser differ way to show cookie, most are in their option/preference menu, and you can find it in one of many tabs in option window.

This is not only problem, if you can find where is cookie menu, you have to find yourself or some browser it has filter box to help this hard work, why i say like this cause in real world you not view just one or two websites, right? you view many websites a day, and cookie will show in format one cookie variable per line, Don't Forget one website can has many cookie variables and you have to find which cookie record that relate to the website you are searching.

That all, first you have to open web that you want to view cookies, then just type above command in address box, it will not bring you to new tab or new window, you will not loss your current url address, it will show again after complete javascript command, this is not any hacking, it's javascript command, what is the result of this command? it will show a popup window like picture in this post (picture at top of this post), in picture it show cookie of https://addons.mozilla.org, will appreciate if you leave a comment what you think about this tip.
