Multiple Homepages in Mozilla Firefox
With all of the websites I frequent at work, I'm always opening the same tabs over and over when I get on the clock. Annoying to say the least. You can imagine my joy when I figured out how to have multiple homepages in Firefox.

Or open the tabs you want as starting pages and press “Use Current Pages” in the Options.
Or use Opera. It has support for 9 sites on speed dial (little thumbnails of the site for your homepage).
I’ve never been high on Opera. The UI has always been a major turnoff for me. And I now depend on my Firefox plugins for development.
To open a blank tab, add a pipe after the last url.
