(Toolkit :: Downloads API, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.15) Gecko/20080623 Firefox/2.0.0.15

If you have a new version of a file and are downloading it from a website(to verify the submittal for example), firefox sometimes will retrieve an older version.  I believe the problem is that when you click "open" in the download manager, it retrieves the earliest version of the file found in the cache.  Reasons I think so:

1.The version of the file that opens up when I click "open" doesn't exist on my hard drive.
2.After doing this repeatedly, copies are put into the cache.  Eventually, the version that is outdated is booted out and replaced with one of the new versions.  Therefore, after repeating this process 10 times or so, I found that the download manager retrieves the newer version.

Reproducible: Always

Steps to Reproduce:
Let's say we have a file, call it fileX
1.Put fileX into the browser cache.
2.Edit fileX and upload it.
3.Download fileX.
4.Click "open" in download manager
Actual Results:  
download manager retrieves the older version.

Expected Results:  
download manager should retrieve the version I uploaded in step 2.
