Fleck is an extension for the Mozilla Firefox browser developed in Javascript, which is used to instantly make, maintain and consult annotations and personal comments of each user about the web pages you visit.
Fleck is presented in the form of a toolbar, and allows us to mark and collect data from the websites we visit, as well as access them every time we enter the website in question.
You have options to stop a train: from simply writing down comments, to posting them to blogs, bookmarking them, checking notes history, sending links or sending emails with a specific entry.
You can free download Fleck 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
