Translates websites in your browser without using the cloud, a different approach to that of google, should protect privacy better. It doesn't handle mixed pages well unfortunately (so the other languages in my RSS feed are not being detected) and I can't force it to translate the pages but otherwise it seems to do a similar job.
I see both an icon on the right end of the address bar I can click to manually translate pages, and the ability to click on the addon from the extensions list in the toolbar to open a popup to translate arbitrary text.
