As you may know, since Firefox changed it's version to 5 (right now I have Firefox 10), Google Toolbar is not compatible with firefox anymore.
I used the google toolbar quite often to translate words in internet quickly without opening a new tab to let the word translate via extra website. It was quite useful for me just to point at the word which I want to translate and just a little popup came and showed the word in my language.
Since I'm even not able to install the google toolbar (also not able with compability reporter anymore), I'm searching for a firefox addon which fullfills the same functionality (translating single words with simply pointing at them). I used quick translator long time but it seems it's also not compatible anymore. Anyone an idea?
