LJlogin Firefox Extension
Are you a Firefox user with multiple LiveJournal accounts (whether for roleplaying or other purposes)? Weary of constantly having to go back to the login page to switch accounts, especially if you forget and do something while logged into the wrong one? Well, now you're in luck, because LJlogin will help you by showing you who you're logged in as and -- if you use Firefox's Password Manager -- allowing you to switch between them.
LJlogin is currently at Version 2.2.1, and can be installed by clicking this link. Feature changes across versions can be found at the Roadmap. The other links at the top of the page will take you to other views of LJlogin's evolution over time.
