Never heard of metabolt so I googled it. I downloaded it, kinda tricky to find the real metabolt ap, lots of ads. But it worked. It is a text only client. Logged on and then just logged back out. Now firestorm works again. Thanks for the info Kat!
So far none of the solutions have resolved the issue. Reinstalling Firestorm brings me to the same problem. Why is there not a way to accept the terms from Second Life.com?
