I'm guessing that Xactimate is dynamically generating a PDF document rather than a plain web page. But maybe this will help confirm what kind of file it is:

• If you rename the downloaded file with a .pdf extension, will it open properly in Adobe Reader/Adobe Acrobat (or your preferred PDF software)?

• If you rename the downloaded file with a .html extension, will it open and lay out normally in Firefox?

Note: by default, windows may hide some of these file extensions when you are viewing file names. You can disable the hiding using the steps in this article: http://windows.microsoft.com/en-us/windows/show-hide-file-name-extensions

Thank you for the info but what I would like to do is have the browser perform as before. It use to open a preview of the document I was creating on the browser in a new tab or window. It doesnt open the preview anymore.

The weird thing is I went ahead and downloaded chrome and it works. But FireFox and Explorer do not.

It is a pdf file. I downloaded addobie reader and can now download and print but still no preview as before.

You would have to disable the built-in PDF Viewer to make Firefox use a plugin like the Adobe Reader.

It is also possible that the server sends the file with an unsupported MIME (content) type.

You would have to check that with an extension like Live Http Headers.

If you change your setting for PDF files in the Options dialog, Applications panel (see the article cor-el posted the link to), can you get Firefox to preview the document? If not, the server might be sending disposition=attachment to force a download. There is an extension to work around this that you could try: https://addons.mozilla.org/firefox/addon/inlinedisposition/

Thank you for the reply. I didn't want to disable the built in PDF viewer. It disabled itself. I added adobe reader only after it quit working. I also noticed that it wont open PDF files for other sites like banking. It will however preview gmail. But gmail doesn't open a new window like the other sites.

I added the plugin (linedisposition) you spoke of and it didn't help.

What is your current selection for PDF files? Is it set back to Preview in Firefox or one of the other "in Firefox" options?

"If you change your setting for PDF files in the Options dialog, Applications panel (see the article cor-el posted the link to), can you get Firefox to preview the document? "

Thank you. This solved my problem. I still don't under stand how it was changed in the first place. I'm not computer savy enough to have changed this myself the first time. But with your info I now changed it back. Thank you very much.
