Rated 5 out of 5 stars

Works fantastic and makes downloading from Mega so much easier. Thank you!
However, I have an issue with FF 25 Beta - add on does not work anymore (worked well with 24 Betas and Official Release). Would it be possible for you to check it? Error message I got was 'this im is undefined'.

This review is for a previous version of the add-on (0.5.22.1-signed.1-signed). 

Thanks for reporting the issue, version 0.11.6 has been released fixing it.
