User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: Gecko/2008120122 Firefox/3.0.5

The problem the following when using Windows 7 Beta:

* I try to install any addon to Firefox 3.0.5
* the installation dialog appears. I click the "Install" button after the countdown has concluded
* Firefox waits (I assume trying to download the extension). It times out with the following error:

Firefox could not install the file at 
because: Download error

I also punched this URL (or any other such .xpi extension URL) into Internet Explorer, and it too could not communicate with the site. However, I switched to Linux on the same machine (same hardware, same network card, etc) I have no problem accessing extensions, downloading and installing them. I was skeptical that the problem was specific to Windows 7, and I still am, so I would appreciate somebody trying this and confirming/refuting the observation.

Reproducible: Always

Steps to Reproduce:
1. Choose an extension to install in Firefox 3.0.5
2. Try to install it, or try to access the URL directly in any web browser

Actual Results:  
Error downloading the extension (accessing the site) is reported

Expected Results:  
I expected the extension to be downloaded and installed

I tried to see if the use of a secure HTTP server was the problem, but I had no problem accessing several other secure servers. I see no network access error messages in Windows, and can easily browse other sites even while unable to access the extension URL.

Hi Siddharth,

I checked the cache; it was enabled. I removed AVG anti-virus, which on Windows XP had not blocked Firefox. That seems to have cleared up the problem. So it's AVG's problem. I'll leave it uninstalled so I can enjoy Firefox.
