funny thing is.... all these add-ons were to make my job a lot simpler and also to save my time lol. It's kinda ironic.
FireGestures -

You use mouse gestures to perform a specific function that you program yourself. For example - see the pix above? green line is where your mouse is going. Place your mouse pointer on the link and then hold down right-button and then perform a specific mouse math (from the pix - down and right). I did program it to open a new window. This is lot better than clicking on right button and then click on "OPEN IT IN NEW WINDOW"
I also programmed my mouse gesture to close window when moving it left and right. Also - when my mouse pointer is on unclickable link area, I move down-right to open new window and down-right to open new tab. My clockwise movement is to reload the page. BOX-shape gesture (down-right-up-left) is to open its OPTION window to configure/tweak it.
It's truly amazing and a huge time-saving program!!! It probably saved my time by like 40%! I beg you to try it! You can program the mouse gesture as according to your sign language gesture to perform a specific function.
