Rated 5 out of 5 stars

Love the way this works, but getting one serious problem - *massive* RAM usage when translating some pages. I'm using Firefox 21.0 on Ubuntu 13.04 (64 bit). For example, if I try and translate the whole page at http://www.hs.fi/ from Finnish to English, Firefox RAM usage goes up from 350MB to 2.9GB (and CPU to 26%), and grinds my (quad-core, 4GB RAM) system to a standstill. Still giving it 5 stars - just hope the issue with RAM usage can be fixed!
