There is now a new version of the bot out there wich is .exe based and not browser based, and it also comes with a program to manage all your profiles/users.
A little info about the YAEB Binary Manager:
The Binary Manager is a single program you can use to keep track of and launch all your bots you run. From this Manager you can create & load profiles for each bot, start them one or more at a time, restart or stop them one or more at a time. The cpu usage and memory usage of each bot running is displayed beside each profile name. To upgrade to use a newer bot version for each account, it's as simple as clicking a button and pointing it at a new YAEB build. Here's what it looks like (with names omitted to protect the guilty):
