asdf is a Firefox plugin that provides quick access to the web browser's keyboard shortcuts. It can be easily installed and configured, even by users with no experience in software applications.
Since this is an add-on, asdf does not come with an installation package. It is quickly integrated into Firefox and only requires a simple restart of the web browser.
So, the tool basically creates an extra option in the View menu of Firefox, called "Keyboard shortcuts". Clicking it redirects you to the hotkey section of the web browser help documentation.
In other words, asdf does not come with original features, but merely offers you a quicker way to getting to know what keyboard shortcuts you can use in Mozilla Firefox. This can be very helpful once users get familiarized with the web browser, since it can significantly improve their navigation experience.
The lightweight tool does not put a strain on the computer's overall performance, since it runs on a very low amount of CPU and system memory. It has a good response time and has not caused Mozilla Firefox to hang, crash or pop up error dialogs during our testing; we have not come across any problems.
On the other hand, the add-on has not been updated for a very long time and does not support newer versions of Firefox. Other than that, asdf can be seamlessly handled, regardless of the user's skill level.
