[gentoo-user] Catastrophic bug in the firefox 'ProfileManager' function

[walt <w41ter@gmail.com>]

I suspect most people don't even know firefox has a ProfileManager, but
I'm here to warn you not to use it.  It just cost me years of bookmarks
and saved passwords.

For testing purposes I invoked firefox-bin with the -ProfileManager
flag (don't do this, it's broken!) and created a fresh firefox profile
with the name "temp" as I've been doing for years.

I ran the "temp" profile while doing my testing, quit firefox and then
re-invoked firefox with the -ProfileManager flag and used it to delete
the "temp" profile because I didn't need it any more.

Unfortunately, deleting "temp" also deleted the "default" profile I've
been using for years, which had all of my bookmarks and saved passwords
and maybe other stuff I haven't even thought about yet.

I'm copying an old firefox profile from another machine that's four
years out of date.  Maybe I can rescue an ort here or there.

What a fscking disaster.

Lesson learned:  if you need to start firefox with a fresh profile,
just move your ~/.mozilla directory out of the way and let firefox
create a new one from scratch.
