Really like this addon, very handy and easy to use.

Would love to give it 5 stars, except Context Menu option not working properly.
ON options page;

Translator Button Type:
Injected Button
Context Menu

When you choose context menu option, then click save changes, it works perfect, until you restart browser, then it disappears from the context menu.

When you do the same with the Injected Button option, it continues to work perfectly.

Please fix, so i can give it 5 stars
