By far the best translate addon.
it has all features that i need.
1. when selecting text, the translate icon appears instantly and don't need to click on the toolbar icon.
2. the option to choose two languages.
because we can select english as first and our own native language second.
this option wasn't working in old days but now that it works it become perfect.
Thank you very much
To those friends that say it can read all texts in page, it is opensource so you can check its source and use the source as a temp addon. :)
Although i think such a talented developer that know what user needs (this show he is also a user of his own addon) won't do malicious things :)
