With 8.0 version of Firefox, clicking links to .tif files on a java web app are being downloaded as .ppt, .part.ppt., or .ppt.part. The change of name to PPT causes them to associate with powerpoint. IE opens the files normally as .tif as expected.
When using java based webapp to view a remote directory, clicking .tif files offers the standard "Open" dialog. If you select open, an error is produced saying file is not a valid powerpoint file. Selecting download will download the file as a .ptt, .part.ppt, or .ppt.part file in the temp directory with a seemingly random unique filename as if the system was creating a temp file. Going to the same web app under Internet Explorer works properly and will view or download the file as a .tif image file. This had been working fine previously to the 8.0 update.
