it's best script control addon

They are collecting "certain personally identifiable information" and moreover:
"We may employ third party companies and individuals to facilitate our Service, to provide the Service on our behalf, to perform Service-related services or to assist us in analyzing how our Service is used."

This kind of behaviour is unacceptable for any privacy conscious person. If you want to collect any user data you should make it opt-in. Most Firefox users care about their privacy - that's the prime reason they use it.

Such a shame the privacy policies of this otherwise great addon. But it´s a nice lesson of how open source doesnt mean private. This addon collects personal information and I´m not happy about it as you can guess by my rating.

2.9.8 completely broken, even Dashboard doesn't open, no scripts show as installed or are used. Have Waterfox 64-bit, but seems it affects Firefox users too.

New version 2.8.8 doesn't work!
UPDATE: version 2.9.9 works fine again, amazing add-on

v 2.9.8 doesn't work anymore
* update 2.9.9 work again :)
