Rated 5 out of 5 stars

Upgrading to 5 stars because it now has per-site exceptions. It'd be even better if there were a GUI widget for doing this quickly, but I don't mind. (I still would like to disable u and d permanently, but it's not a big deal.) Overall, I think this is an almost-essential extension if you use a Lenovo laptop with a pointer stick or otherwise don't have a scrolling mouse.

Handy Rated 5 out of 5 stars

Vinkey works neatly. I like it a lot to be able to use keystrokes for some tasks.
When you are not addicted to your mouse, try vinkeys.

This review is for a previous version of the add-on (0.1). 

Thank you for your review, could you tell your firefox version and what OS you use?
Or you can wait for version 0.2 checked by AMO, i've submitted it.
Version 0.2 have follow changes:
chang gg to g to scroll to top
add one key bindings.
ESC - exit edit mode to make the keybindings efficient
Maybe the first change make you get things done.
Thanks.
