Great, but... Rated 4 out of 5 stars
First, I'd like to say this SHOULD be native in Firefox - if someone doesn't want their images on transparent backgrounds, they should add the BG themselves. Having backgrounds added to every transparent image is retarded.Having said that, this fixes the issue perfectly. My one complaint for this add-on is that I have to disable then re-enable it every time I start firefox, or it doesn't work. Seriously, this is incredibly annoying.This review is for a previous version of the add-on (initial.rev24.1.1-signed.1-signed). This user has a previous review of this add-on.
