In my role I give a lot of presentations which involve demoing multiple sites in a browser.
To have all the URLs preloaded when I start the presentation, I’ve experimented with a number of tools:
What I need is a painfully simple and reliable way of opening multiple tabs on any PC.
Step forward URLOpener. You simply paste in a list of URLs, click submit and it will open them as new tabs. Done.
Put any better ideas you may have in the comments section below.

Control T; Control V in Firefox and IE7? Too manual maybe…
Then I have multiple windows. Still no.s 1 or 4 for me so far!
If it’s simple you want, email them to yourself in Outlook then click on them one by one to open them.
