I've used the SeleniumIDE extensively on Linux (Ubuntu) a while ago, now I'm trying to get it working on a Mac (OSX v10.9) in the Firefox browser. I have it installed but it doesn't seem to be interacting with the browser. When I try and record scripts, nothing happens. If I manually add a test case for open('') I get

[info] Executing: |open('') | | |
[error] Unknown command: 'open('')' 

See this screenshot for more background:

Are you using some combination of the supported browsers / OS / IDE listed here? Adding a little more detail that documents your precise setup might go a long way to getting a quality answer instead of guesswork. – bmike Dec 3 '13 at 18:13
Added more info, the browser, the OS version and a screenshot showing the issue – Michael Durrant Dec 3 '13 at 18:17

The answer was that you put the Base URL up top, e.g. and then you put the rest of the url, e.g. /images in the 'Target' field.

If you only want to go to the base page of the site (e.g. "") you just use that for the BaseURL and then use in the 'Command' line use 'open' with no parameters) but keep the Target field blank.
