is the safelist working in the newest beta,i installed restarted pc,ran safelist database and then opened firefox.hips popped up asking to allow/deny ff and at bottom of box where it says suggestion it was not found in comodo safelist database?surely ff has got to be in there?

The safe list is working.

Remember that it analyzes a program and attempts to match it to a database. There can be a number of reason why it didn’t find firefox, from md5sum mismatches caused by extensions to version changes. It takes some time for new versions to be included and it would be doubtful if they ever include other keys for applications that are modified by extensions, modules, or plugins.
