To test everything, follow all the links both with and without a a TIFF plug-in (such as QuickTime or AlternaTIFF) installed. Note that whether you have any other Mozilla browser windows open when you click the links has an effect on Mozilla's behavior.
There are two sizes of images because Mozilla used to behave differently for small file sizes. I no longer see any difference, however.

1. SMALL (1.5K), no TARGET, image/tiff
2. SMALL (1.5K), TARGET=_self, image/tiff
3. SMALL (1.5K), TARGET=_blank, image/tiff
4. SMALL (1.5K), TARGET=foo, image/tiff
5. LARGE (80K), no TARGET, image/tiff
6. LARGE (80K), TARGET=_self, image/tiff
7. LARGE (80K), TARGET=_blank, image/tiff
8. LARGE (80K), TARGET=bar, image/tiff
The problems seem to be specific to MIME type image/tiff. The following tests are identical to the first set, except that the files have MIME type "image/x-tiff" instead of "image/tiff". Note that some TIFF plug-ins may not handle type image/x-tiff.
9. SMALL (1.5K), no TARGET, image/x-tiff
10. SMALL (1.5K), TARGET=_self, image/x-tiff
11. SMALL (1.5K), TARGET=_blank, image/x-tiff
12. SMALL (1.5K), TARGET=foo2, image/x-tiff
13. LARGE (80K), no TARGET, image/x-tiff
14. LARGE (80K), TARGET=_self, image/x-tiff
15. LARGE (80K), TARGET=_blank, image/x-tiff
16. LARGE (80K), TARGET=bar2, image/x-tiff
