The option of browsing incognito over the Internet, introduced by the Google Chrome browser, allows the user to enter any website without leaving a trace of their data, so that their security and privacy is protected. Stealther is an extension for Firefox that does a similar function, with the advantage that now you can navigate incognito not in a window that you have open (as it happens with Google Chrome) without with all the windows, thus increasing your privacy.
Stealther allows you to deactivate history, cookies, history of downloaded files, cache memory, data sent by form, and so on. Never a program of just 15 kb gave so much privacy in the world of computing. And it is also completely free.
You can free download Stealther 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
