Hello
I use a dictionary while visiting this website very often. Even tough I always (or almost always) understand the whole plot - I would like to learn more more and more vocabulary, which is the most important, of course.
I use
http://dict.pl - some polish-english dictionary but it is not very comfortable to switch the windows during writing or reading this page, checking the world and switching the window again. What Im looking for is a plugin which lets me to translate an unknown word very simply. If you have Firefox (or maybe IE as well, I dont know), you can see a Google/ebay/wikipedia/whatever plugin which lets you to search anything very fast (top right corner). Is there any dictionary which can be situated similar to this google gap? And what is very important for me - it should search without changing my current website - just connecting, checking, showing ...
Sorry for writing such a long essay but it was hard to explain what I am looking for

Thanks in advance,
Greets.
