FireFox is soooo much better than IE!!
Just an FYI - we've gone away from using IE as our browser for ARM. The "heavy" users complained that IE was too slow, froze up too often and often required restarting a new browser window when nothing appeared to be happening. With Firefox, no complaints!
If \ when you do use Firefox for ARM, you’ll need to install the add-in Remote XUL Manager and add the server where you have Workspace installed. The downside is that using Firefox with EPMA is a bit quirky when drilling down into the metadata.
