Click&Clean is a Firefox extension, which helps you to clear your internet history and protect your privacy in 1-click without any prompts. Advanced security features are also included e.g. the ability to run an external application (for example: CCleaner, WiseDiscCleaner, BleachBit, Computer Janitor, ...) which will perform more deep and secure cleaning.
Using Click&Clean Add-On for Firefox you save your time and enhance your sense of security and privacy.

If you really want to deep clean your computer you should consider using Click&Clean together with the CCleaner (1-click automatic cleaning supported), so we highly recommend you to install a CCleaner (for Windows users) . CCleaner is a FREE and powerful utility which allows you to delete unused and temporary files from your computer.

Next you will need to configure Click&Clean. Select "Tools" from the "Firefox" menu. Click "Add-ons" on the top menu. > "Click&Clean" > clicking the "Options" button will open the "Click&Clean Options" window (Pic. 1).
Clicking the "Clear Now" button will open the "Clear Recent History" dialog box. Then select the items that you want to clear when a running Click&Clean or when Firefox closes (Pic. 2).
Using the external apps (require pre-configuring) will give you more options to deep clean your private data. That means, clicking the TP roll icon will clear your browsing history and then automatically runs the external app (like CCleaner, WiseDiscCleaner, Computer Janitor, ...). The most correct would be to use an external application when you close Firefox (option "run external application when browser closes").
Next, you can close all tabs (except latest active) and to clear browsing history with a single click, by selecting the additional options "Close all windows/tabs before clearing" and "Do not close the last active tab".
At the completion of configuration, the Click&Clean is ready to run the cleaning process in a single click or when you close Firefox.
