There are no OPTIONS in the TOOLS menu!!!??? WTF (using mac OSX / firefox). Useless help.

That is because Firefox developers are gone wild or mad. They update their user interface every month and causes troubles to other developers and general users. Now they don’t offer option to turn off Javascript.
Just wait a few moment to see the updated version with new technique.
