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('http://www.google.com') I get
[info] Executing: |open('http://www.google.com') | | | [error] Unknown command: 'open('http://www.google.com')'
