Over the years the Internet has changed a whole lot naturally so have the web browsers. Some may argue that it is the web browsers that define what the Internet looks like today. For instance, if it wasn’t for the web browsers websites would not be able to provide you live notifications right at your desktop. Luckily, as these browsers give websites more power, they also make sure the control is always in the hands of the users.
This is why they let you manage what a particular website can do via Permissions and Cookies. Cookies are small packets of information websites store on your PC. These can be aggravating, compromising your privacy and filling up your storage. Optimizing your browser’s settings is a critical step in using the Internet securely and privately. So here’s how you can check permissions and cookies stored by websites on web browsers like Chrome and Firefox.
Google Chrome
Things couldn’t get any simpler on Chrome when it comes to checking a website’s permissions and the cookies it is using. Any time you have a website opened in Chrome, you will notice a small 
To change the global settings, click on the three-dot menu button in Chrome and select Settings. Click on the hamburger menu icon in the top left and then click on Advanced settings to expand it. Here, select Privacy and security. Or you can simply scroll down to the bottom, and click Advanced. Under the Privacy and security settings, click on Content settings.
Here you can set the global settings for every permission and for cookies as well as view individual websites that have been allowed or disallowed the said permission. You can also add or remove websites from the Blocked or Allowed lists.
Firefox
Firefox too has the same icon on the very left of its address bar as Chrome. Although, when you click on it you can only see the permissions you have granted the currently opened website. Well, not at first. But you can click on the small arrow next to the website’s name and then click More information. Alternatively, you can right-click on a website, anywhere that does not include a hyperlink, and click View page info.
In the new window that opens up, select the Permissions tab if it is not already selected. Here, you can see and manage the permissions for the said website. By default, Firefox too uses the global settings unless you change that for an individual website. You’ll have to uncheck the Use default option to be able to change permissions.
Firefox also lets you see which permissions you’ve configured for different websites and change them all in one place. Firefox’s settings for Cookies and permissions are separate but can both be found in the same section place. To manage cookies and permissions, you’ll need to click on the Firefox menu icon 
and select Options. On the left you’ll find a section named Privacy and security, click on it.
Under History, at the bottom of the subsection, you will find links to clear your recent history or remove individual cookies. Click on remove individual cookies. A pop-up window will appear listing all the stored cookies by different websites. You can select and remove them individually or remove them all at once.
Permission settings are placed a bit lower on the very same page. Scroll down until you find the Permissions subsection. You’ll find a Settings button next to each permission.
Clicking on it will let you add or remove websites from the memory. A drop-down menu next to each website lets you Allow or Block the said permission for the website.
