Status: RESOLVED WORKSFORME

(Toolkit :: Add-ons Manager, defect)

[Peter Kroll]

User-Agent:       
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

when i visit the site above or the regular mozdev extensions page then i click
to install an xpi extension I'm prompted with a "download manager" which lets me
click OK or Cancel. I click Cancel. Everything is fine.
However, when I click on a different xpi to install it will attempt to install
both extensions sometimes causing Firefox to crash or forcing me to install the
extension I had previously cancelled.

Reproducible: Always
Steps to Reproduce:
1. Install Firefox
2. Visit a site with multiple extensions available.
3. Click "Extension A"
4. When prompted Cancel the installation
5. Click "Extension B"
6. When prompted click Ok to accept the installation

Actual Results:  
Firefox either installs the first Cancelled extension or it will install both
the cancelled extension and the authorized extension.

Expected Results:  
Only the second extension should be installed.

Presumably this is part of the problem from Bug 229600, not sure if it's close
enough to be a duplicate though.

I wasn't sure either. Seems to be a similar problem. But this issue deals with
cancelling the first install, so I filed it seperately.

In my testing, the second extension was installed, then the first, and then a
crash occurred.

Probably related to bug 229600, yet different enough to warrant a separate bug.
