Status: RESOLVED DUPLICATE of bug 262854

(Toolkit :: Add-ons Manager, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

It has taken me quite a while to work out the cause this problem. On all my
machines I keep the disk cache size set to 0kb for various reasons. When the
disk cache is set to 0kb, extenions will fail to install directly, unless I
first save them to my desktop and then drag them to the Firefox window.

On setting the cache to 512kb, installation starts to work correctly again.

Reproducible: Always

Steps to Reproduce:
1. Set browser cache size to 0kb and clear your cache (clearing might be optional)
2. Go to http://toolbar.google.com/firefox/extensions/suggest/install.html
3. Click 'Agree and install'.
4. Click 'install'.
5. Observe output in the attached screenshot.
Actual Results:  
"Because: download error" message appears.

Expected Results:  
Extension should be installed correctly, or alternatively an error indicating
that the extension installer cannot function unless disk cache is enabled should
be displayed.
