Very neat little FireFox AddOn: MeasureIt.
- Click the MeasureIt button in the status bar or toolbar to turn it on/off.
- Click and drag out a ruler box.
- Click and hold to move the ruler box.
- Use CTRL + Arrow Keys to nudge ruler by 1 pixel.
- Use CTRL + SHIFT + Arrow Keys to nudge ruler by 5 pixels.
- Click the “X” to close that ruler or click outside of it to begin drawing another ruler.
- Use the ESC key to turn off MeasureIt.
Word! What other FireFox AddOns are you using for your creative endeavors and web adventures?

Love Love Love that tool, I use is almost daily!

I use Web Developer’s Toolbar and Firebug almost every single day.
firebug every minute…
I use and love MeasureIt as well. Other Firefox tools I like are ColorZilla and of course Firebug.
FireBug rocks!!!

i use swatch, a mac app.
Definitely one of my favorite extensions. Simple and does a great job.
Sometimes when I want a quick fix for this on my Mac I’ll use the screenshot keyboard shortcut (Cmd + Shift + 4), which also measures the area which you select.
yes. i use that all the time.
Yup, love this one. Use it almost every day. I’m also a huge fan of Colorzilla (like everyone else).
yes.
