I was told that there is a setting called move lock to prevent your avatar in Second Life from being moved. Is there such as a setting in Firefox called move lock ? How do you find the setting ?

My Second Life avatar was grief-ed by being flung into mid air by either a script, a push or a repluser. I personally am convinced that is was a script of some sort. Another avatar di try to aid me by sending a teleport request yet every time my avatar landed in the same area I bounced back to both mid air and the land boundaries of where I was at the time.
