Hi forum members,

polonus
It’s not working here too 
Hi Tech,
Had to reinstall it, to make it working again.
It could have been as some suggest at a mozilla forum, that it is an incompatibility with another add-on or plug-in.
I have not been aware of that. At least it is functioning normally now. I personally think it had to do with a particular update.
Have you heard news about the hick-up so far? Are there others
with problems?

I have version 21, build 3532 of site advisor. It’s been working and still is working fine here Polonus. 
There are several known issues with it.
The most reported problem is:
If you use FF with plugins/add-ons it can give problems and even corrupt the user in FF.
Sometimes creating a new user profile solves it, other times a complete remove/reinstall is needed.
Although there are several problems reported by many people, McACrap is still denying that there is anything wrong with it and that is what bothers me the most. There definatly is a problem. They could at least mention somewhere on their website that it can give problems if you use FF with certain add-ons/plugins.
