461456 - Adobe Plugin crashes Firefox when using object with URL that doesn't contain ".pdf"

Status: RESOLVED DUPLICATE of bug 434593

(Core Graveyard :: Plug-ins, defect)

Description

[Philippe Laflamme]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008092510 Ubuntu/8.04 (hardy) Firefox/3.0.3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008092510 Ubuntu/8.04 (hardy) Firefox/3.0.3

This may concern the Adobe Acrobat plugin more than Firefox, but still I'm reporting this here because there seems to be other issues related to the plugin.

I'm using an object tag to embed a PDF file into a web page. This PDF is dynamically generated so the URL in the "data" attribute is not simply a reference to the file on a server.

More specifically, the URL contains only a path portion without a file part: http://server/foo/bar/?param=value

URLs of this form crash Firefox on Windows and dont display anything on Ubuntu.

We've created a test case to see what URLs actually crash firefox, and it seems to be any URL that does not contain a file part that as a ".pdf" extension.

We've created a servlet that sends a PDF, whatever request it receives. If the URL is of the form: http://server/foo/bar.pdf?param=value, everything works as expected. Any other URL form that does not contain bar.pdf will crash.

Reproducible: Always

Steps to Reproduce:
1. Use an object tag with data="http://server/foo/bar" type="application/pdf"

Actual Results:  
Ubuntu: firefox displays nothing (the object tag seems to be 1x1 pixel)
Windows: firefox crashes

Expected Results:  
PDF displayed inline

Which content type does the server send for the file ?
For the windows crash see http://developer.mozilla.org/En/How_to_get_a_stacktrace_for_a_bug_report

bp-e94f0b9e-aa1b-11dd-8891-001a4bd43ef6 seems to be bug 444930

After reading the comments in bug 444930, I have disabled the "download embedded 0.5" addon and the problem has gone.

This is a duplicate of 434593 (although the steps are different).
