This extension adds a new "Translate" option on the right-click menu when you have selected some texts on the page.
Click on the new option will simply opens Google Translate page in a window pop-up, with the selected content automatically loaded in Google Translate page.
The window will by default appear on top left side of your screen, you can move or resize it for your preferences. The extension will translate next item on the same window if you do not close it.
The extension simplifies the process to translate some text during view websites, as opening a new tab and copy-paste it is time wasting and interruptive.
