Comprehensive Keylogger Add-on for Firefox

Nifty Keylogger is a powerful add-on designed to capture keystrokes within the Firefox browser environment. This tool logs various keys, including ALT, SHIFT, CTRL, arrow keys, and BACKSPACE. Users can access the log by pressing ALT + SHIFT + K or ALT + SHIFT + O, which opens a window displaying the logged keystrokes. The add-on is built to minimize interference with the user experience, ensuring no unsolicited pop-ups disrupt the browsing session while remaining inconspicuous in the Firefox menu without any visible text.

The functionality of Nifty Keylogger extends beyond Firefox, as it is also compatible with Chrome. It operates on all versions of Firefox starting from 3.5 and is effective across various operating systems. Notably, version 1.3 introduced the ability to clear the log file using ALT + SHIFT + D, enhancing user control over logged data. This add-on is categorized under Security & Privacy, specifically focusing on Anti-Spam & Anti-Spy functionalities.
