Rated 5 out of 5 stars

I'm using the add-on as an alternative to the official flash player since the add-on doesn't require admin permissions to install.

The only thing is that it lags behind the official version. I hope it will be updated soon to flash 25

This review is for a previous version of the add-on (24.0.0.221).

New version was uploaded here some days ago. On every release users have to wait for Mozilla review team to "check" my files. You can download addon manually: see link in developer's comments below.
