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
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.
