I have some pages where i can never open PDFs. Its not only on microship sites. I see only a blank pdf page and the acrobat progress bar, which shows the download status 340kb from 345kb loaded. 

In my windows tmp folder i can see the downloaded .tmp file. I have the locked file unlocked and copied. The size of the File is exactly 2000kb. The original size of the file is 345KB. I can open the corrupted 2000kb file in fx manually and also in acrobat reader without problems.

I have asked some people on mozillazine daily build thread to test the link and some of them have also problems. 

You can it read here:

Reproducible: Always

Steps to Reproduce:
2.With my main profile it opens never.
3.With a clean new createt profile it opens sometimes. But mostly not.
Actual Results:  
Blank PDF Page
Adobe reader Progressbar shows 340KB of 344KB
After some seconds, reports adobe a error. By reading of the document is a problem occurred(14). (translate from german)

Expected Results:  
Complete downloaded and opened PDF.

- tested with clean Profile without extensions
- tested with disabled OOPP
- IE has no Problems with this PDF
Version: unspecified → Trunk
>IE has no Problems with this PDF
But IE doesn't use the same plugin.

The acrobat Reader NPAPI Plugin is using http range requests and a buggy server can break the pdf in such cases.
Have you already tried to disable the plugin and open an external Acrobat Reader window instead ?
I have disabled the pdf plugin in addon manager. Download works and acrobat open it. The file size in the tmp folder is also correct. Plugin Version is

IE and Fx use the same nppdf32.dll as pdf plugin. Fx use the npapi plugin 	additionally? Maybe there is the problem. Then i see a lot of buggy servers. I see it not only at microchip sites.
Its not only on trunk also with new Namaroka 3.6.4pre i have the same problem.

My last Namaroka build was 20100217 and working fine.
Namaroka has the pdf problem since 20100408, 20100704 working fine. 

>IE and Fx use the same nppdf32.dll as pdf plugin.
No, IE doesn't use npapi Plugins since IE5 or IE6. IE needs ActiveX Plugins.
The np in NPpdf32.dll stand for Netscape Plugin.

TheRave, can you perhaps narrow down to a one-day range when the problem appeared?

If you can, I'd be interested in the changeset ID (the http:// url) from about:buildconfig for the last working build and the first broken build.
The branch range is the Lorentz landing.

The trunk range has a likely culprit, given that Acroread uses the cache-as-file stuff: bug 548217.

Yeah, probably. I'll look at this first-thing Monday. What exact version of Acrobat Reader are you using? Beltzner, this needs to block.

Verified fixed for 1.9.2 by passing mochitests. I cannot get the site mentioned in comment 0 to fail to give me a pdf on a clean machine.
Keywords: verified1.9.2
The pdf viewing works now. Thanks for the fix.
Shouldn't this not be marked as verified as a whole since no one has checked it on trunk?
TheRave seems to have verified it. I checked using an hourly build, I think, also.
Yes. I have it tested on trunk & namaroka.
