Open Multiple Firefox Tabs from Command Line
Now that I work on Firefox Developer Tools, I'm really starting to learn some of the tricks of building, debugging, and launching Firefox. Once I start using Firefox at a developer level each day, the more I become amazed at how configurable and easy to work with Firefox is.

Since a good portion of my day is spent working on the Firefox DevTools debugger inside a browser in what we call "launchpad", I need shortcuts to make launching and setting up Firefox for development quick. The following command allows me to launch Firefox with the multiple tabs I need:

Incorporating a command like this into a setup.shor likewise file to start my debugging makes setting up a development environment so easy. There's nothing worse than creating tabs and typing the same URLs over and over!

![JavaScript Copy to Clipboard]()
"Copy to clipboard" functionality is something we all use dozens of times daily but the client side API around it has always been lacking; some older APIs and browser implementations required a scary "are you sure?"-style dialog before the content would be copied to clipboard -- not great for...
