I have been seeing the words localized string not found in the right click menus in all of the web browsers. Also if I open a image in a new tab, the title of that tab is always "Localized string not found." Here are a few pictures to show what I mean:
The first one is right clicking on a link in safari
The second one is an image in its own tab in safari
The third one is from the upload files window in safari
