Easily Cache Cleaner

"Easily Cache Cleaner" is a browser extension that lets you clean your custom browsing data via the toolbar pop-up. Currently, there are fourteen options to remove (depending on your browser):

Cookies, Form Data, Downloads, WebSQL, Passwords, Plugin Data, App Cache, File Systems, Indexed DB...

To use this add-on, go to the toolbar popup UI, select the item you want, and then click on the Clean option at the top left corner. While the add-on is cleaning your chosen items, a toolbar icon will flash. Furthermore, when the cleanup process is completed, a desktop alert will inform you what data has been deleted.

It turns out that some disabled items might be found in the toolbar pop-up. This is due to a bug in your browser that prevents it from properly displaying such things using the clear-browsing-data API. These items may become available automatically when the API update occurs in the future.
