Worked beautifully... until Firefox 25 Rated 5 out of 5 stars

Returned image functionality to what previous versions of Firefox showed - transparent backgrounds where called for. Unfortunately, with the update to FF25, they're back to having grey backgrounds where transparent ones should be...
Could we get an update to fix this? :)

This review is for a previous version of the add-on (initial.rev24.1.1-signed.1-signed).
