Puntuado con 4 de 5 estrellas

After using this addon for a couple firefox sessions, I have noticed a couple major bugs:
1) The "Translate this" item in the right click context menu disappears after browser restart. The only remedy is to install the addon again.
2) Translating text sometimes doesn't work.

Please fix these bugs. I am forced to use another, inferior translator addon.

(Response to Developer)
I am using Firefox 7.01, Windows 7 With 75 addons.

Please provide what version of Firefox you are using and what OS. I have never, ever noticed the issues you have described so I need some more information so I can recreate the issue and fix it.
