Here is a screenshot of my Yahoo! Messenger (I'm using v10). I don't see an option for starting a chat in the menu. Where is it?

You can have Firefox check right now if it is the default browser:
Tools > Options > Advanced > System Defaults
Then click Check Now.
You will see a prompt which will tell you if it is or isn't. If it isn't, simply click Yes and it will set itself as the go to browser for your computer.
On top of that, you may also need to check the following box:
☑ Always check to see if Firefox is the default browser on startup
When you re-installed YIM, it might have reset your default browser to Internet Explorer.
If that still doesn't work, Firefox might be only thinking that it's set as the default. In which case, go to the Control panel for Programs:
Start > Control Panel > Add or Remove Programs > Set Program Access and Defaults
Then open up the Custom configuration and set Mozilla Firefox as your default browser.
Click OK and YIM should now open up any links in the default browser, which has been set in this case as Firefox.
I believe with the latest version of Yahoo! Messenger, (I think that's 11.) Yahoo! now stores your conversation history online. You can access it from the Yahoo! Mail interface.
Best Answer
The question isn't quite clear about what functionality you are trying to find.
Are you trying to send a message to a single user? If so, that can be done through the "Send an Instant Message" option in the "Actions" menu.
Are you trying to open up a room in order to chat with multiple people? You can do that by using the "Invite to Conference" option in the "Actions" menu.
EDIT
Aha! Well, I have the option, and a quick web search shows me that chat rooms are not available depending on country.
The consensus on the web seems to be that you need to uninstall your current version and download the US version. Not sure if this helps you or not.
