So I spent more than a week to completely re-design extension and add a lot of new features. And now I would like to announce stable & beautiful release that was very welcomed by users.

Also I want to announce that now JSEN is 100% open-source and does not contains any AD or statistics collectiion. That means JSEN published extension source-code 100% equals to https://github.com/barbushin/javascript-errors-notifier
Feedbacks are very welcome. Cheers.
