This is an "ellipsis test" for Mozilla-based browsers. This test paragraph might overflow its implicit boundaries (depending on the width of your browser). If it does, you should see an ellipsis appear at the point where the text gets clipped. If it doesn't, try resizing your browser to a smaller width.

This text smaller and generally won't require a title popup unless you have a low res monitor. Note however, that there is an inherit limit to how small Mozilla will go before it starts clipping its own native components.

This text will probably never show a title tip.

This text will always show a title tip.
