User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8

Downloading large files, particularly PDFs, do not complete. The download stops part way, not always at the same point. In ALL cases, IE8 had no problem downloading the files.

Reproducible: Sometimes

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic+Troubleshooting#Make_a_new_profile

Safe Mode and creating a new profile do not seem to make any difference.

I believe that the problem is related to an ongoing bandwidth issue with my ISP's DSL service. They (Frontier) claim to be working on it but so far have not improved the service any.

IE8 seems to work though the delays better than Firefox does for some reason. It is bad enough now that I am also having problems opening web pages also. The short term fix is for me to do all large downloads in the morning before their service slows down to a crawl.

Please post back once the ISP issue is resolved and let us know if you are still having an issue.

Any update?

Comment 5

[RICHARD OESTREICH]

There is no improvement in the ISP's service in spite of many promises.
I tried installing Firefox 4.0 but had so many problems with it that I went back to 3.6.16. I will try Firefox 4 again when I have the time to spend working out the issues.

Reporter, Firefox 4.0.1 has been released, and it features significant improvements over previous releases. Can you please update to Firefox 4.0.1 or later, and retest your bug? Please also create a fresh profile (
http://support.mozilla.com/kb/Managing+profiles), update your plugins (Flash, Java, Quicktime, Reader, etc) and update your graphics driver and Operating system to the latest versions available. 

If you still continue to see this issue, please comment. If you do not, please close this bug as RESOLVED > WORKSFORME

I was able to get version 4.0.1 working yesterday. I had to remove the Nitro PDF download add-on which I was using in previous versions. So far this seems to improve the download issue.

[Tyler Downer [He/Him]]

Please report to the developers of that addon.

Comment 9

RESOLVED is stretching it a bit.
It is definitely better with 4.0 but still there.
The Nitro PDF download issue ONLY applies to version 4 of Firefox.

Resolved Invalid is used when an extension causes the issue. Are you saying that the issue persists with Firefox 4.0.1 and no extensions?

Yes, but it is not as bad as in previous versions.
I am not entirely familiar with how IP protocol works, but it appears to me that some prompts for data going from Firefox to the internet are being dropped. This symptom also appears when loading web pages. A page will fail to connect but clicking on it a second time will cause it to load normally. If this happens in the middle of a download, then the download would stop???
