As designers make their site layouts, they sometimes want to know what the site would look like with text. You have two choices: Start typing in War and Peace or use Dummy Lipsum to generate the content for you.
If your still reading this and not looking for War and Peace through Google, Dummy Lipsum creates fake content for you site, so you can sit back, check out the site, see if it flows properly, and make modifications while using dummy content.
The extension asks you the how many paragraphs, words, bytes, or lists do you want to generate. There is also an option to show the HTML that the extension generated. The Copy To Clipboard button does exactly that: copies the generated text to the clipboard for later pasting.
The Dummy Lipsum Firefox extension installs flawlessly and no disasters happened. Designers, definitely pick this up, unless you like to type.
