(Firefox :: Installer, defect)

Description

[Tony Chung [:tchung]]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008051204 Minefield/3.0pre
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008051204 Minefield/3.0pre

Setting the "Make firefox my default browser" on the windows installer, does not fire up the browser.  It does however launch the firefox.exe process.   

Process then needs to be killed in order to relaunch browser.

Reproducible: Always

Steps to Reproduce:
1. set IE to default browser 
2. install clean RC1 build on windows
3. On installer, check the "make windows my default browser" checkbox and finish installing.
4. without anything applications open, goto Start > Run and type in a URL in the text field.  (eg. http://www.yahoo.com);  You can also try to double click a local .html file saved on your desktop.
5. Verify nothing launches, but taskmgr shows firefox.exe process open
6. At this point, you have to kill the process if you want to relaunch the browser normally.

See screenshot.  This repros on XP and Vista.
Actual Results:  
Firefox.exe launches with the browser opening a url or launching a local .html page

Expected Results:  
no browser open, firefox.exe process opens in the background.

This is a terrible user experience for users that install firefox 3 for the first time on windows.  Especially since we are checking the browser as default value on the installer.  

I suggest we block on this.

Searching for a regression now, but my hunch is it occurs sometime when the default browser installer option landed in the checkin.

Yeah, this is pretty bad. Let's find a regression range.

I did some more research here.  Looks like it only repros if you have -Profilemanager disabled.  (or the "Dont Ask at Startup" unchecked in profile manager window)

By Default, opening an external URL will open just fine when this is checked.  Removing blocker flag.

The bug where we fail when we *do* ask at startup for a profile has been around for quite some time and I believe the bugs are:
Bug 395891 for Windows
Bug 295248 for Mac OS X
