It finally works, and works perfectly up to now, when previous versions of this extensions were all, here, more than problematic. TrashMail is IMO the best DEA (Disposable Email Address, not Drug Enforcement Agency!) service I know. Very handy and the site's staff is truly dedicated. I switched to TrashMail.net when my previous DEA provider, Emailias, closed its business, and I dare say TrashMail.net is IMO even better. So having a dedicated extension is really appreciated (Emailias only had a bookmarklet). Think DEA, and peace will smile.
