292618 - -profile startup command line option no longer works and Firefox quits silently when used.

Status: RESOLVED DUPLICATE of bug 280199

(Toolkit :: Startup and Profile System, defect)

Description

[Soothsayer]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050502 Firefox/1.0+ (Enf... SVG,MNG)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050502 Firefox/1.0+ (Enf... SVG,MNG)

When starting Firefox using the -profile command line option (e.g. "start
\Firefox\firefox.exe -profile \FFProfile" from within a batch file), Firefox
only briefly appears in the task manager and immediately quits.

This worked fine on the previous build I used (22nd April 2005), but did not
work on either my current build, not a Beast build from approximately 4 hours ago.

Reproducible: Always

Steps to Reproduce:
1. Copy an existing profile (or create a new one) to a new location.
2. Start Firefox using the command "Firefox.exe -profile PathToProfile"
Actual Results:  
Depending on the circumstances one of three errors will occur:

1. Firefox briefly appears in the task list and then disappears.
2. If the stated profile directory does not exist, I get an incorrect error
stating "Firefox is already running, but is not responding. To open a new
window, you must restart Firefox."
3. If Firefox is already open with another profile, it opens a new window using
the open profile, not the requested one.

Expected Results:  
Firefox should opened with the stated profile (or if the profile did not exist,
should have given a correct error message).

I meant to say in my original log that I suspect that the cause of this may be
related to the checkins for bugs 291033 or 74085

I found the problem.

It is not related to the bugs I already mentioned, but rather bug 280199.

Once I deleted the compreg.dat file and restarted Firefox, it recreated this
file and everything worked fine.

I am therefore closing this log as a duplicate of 280199.
