Paywall Label for Facebook, Twitter & Google is a Chrome add-on developed by dejan-tools. This free tool allows users to add a paywall label to Google's search results, as well as to posts and links on Facebook and Twitter feeds.

To use the add-on, simply bring up the context menu on the search result or links from Twitter or Facebook feeds that you wish to label. Then, select "Label as paywall". Once labeled, a small lock icon will appear next to pages from that domain in the future.

If you want to remove a label from a domain, you can follow the same process and select "Unlabel". Alternatively, you can click on the extension icon to view a list of labeled domains and remove the label by clicking on the "x" next to the domain in the list.

With Paywall Label for Facebook, Twitter & Google, users can easily identify search results and posts that require payment to access. This add-on provides a convenient way to stay informed about paywalls while browsing the web.
