Use the chat feature on Facebook? One thing that it really lacks is a way to keep a history of who you talked to and what was said. Thankfully though, this add-on – Facebook Chat History Manager – will give you a way to simply browse through your previous Facebook chats.
All the content you wish to browse through is saved locally, and you can browse through your Facebook chat history anytime online or offline. How about your message security? Here is what the developer has to say.
Your messages are securely stored and only person passed the security check can view saved messages.Note that all messages are stored in your client, this application won’t store your chat history on server.
The only downside I see to this, is when you are installing – the add-on looks for your Facebook ID number, rather than your user name. That might confuse some users. Other than that, it is a great start to a very interesting extension.
You can pick up the Facebook Chat History Manager from the Firefox Add-ons website.
