Localized string not found

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

 

This one is right clicking on an image that is also a link in Shiira
