Drag Images Into Gmail With Firefox

Recently it became possible to drag images right into your Gmail message if you were using Chrome, but I just found out today that I could drag an image into an e-mail using Firefox as well. Maybe the rest of the world knows this, but if you haven’t tried it yet it’s a nice little […]

Multitouch on Firefox

Mouse dominance won’t go away overnight, but soon it won’t be the only way, and after that my bet is that all things user interface are going to change quickly.

Screengrabs Of Whole Pages

From that master of life-hackery Tim Ferriss of all people, here’s a small tip for making a screengrab of an entire page (or any part of a page that you need). I shoulda known there was a Firefox extension. I have found out over time that I have a need for this functionality more often […]

When you specify this preference, a new directory, “Cache” will be created at the path you have set. These other two […]
