install multiple versions of firefox in linux

[COKEDUDE]

Since apt-get and yum won't let you install multiple versions of firefox I will explain how to here.

1. Go to this page and decide which version of firefox you want.
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/
I used this one.
ftp://ftp.mozilla.org/pub/mozilla.or...-9.0.1.tar.bz2

2. Unzip the archive

tar -zxvf firefox-9.0.1.tar.bz2

-z means filter the archive through gzip
-x extract
-v verbose
-f file name

3. Put firefox in its own directory.

mv firefox firefox-9.0.1

4. Make a backup of your profile direcory

cp -r /home/bob/.mozilla /home/bob/.mozilla3

If you use seamonkey or thunderbird there profile info will also be there.

4. Create a new profile so you don't corrupt your old profile.

firefox -CreateProfile "firefox-9.0.1 /home/bob/.mozilla/firefox/firefox-9.0.1"

This is my profile name firefox-9.0.1 and this is my profile directory /home/bob/.mozilla/firefox/firefox-9.0.1

5. Run firefox 9.0.1 from the directory I put it in.

/home/bob/firefox-9.0.1/firefox -no-remote -P firefox-9.0.1

/home/bob/firefox-9.0.1/firefox is my install directory
-no-remote allows to use firefox 9.0.1 and my old version of firefox
-P is the profile option
firefox-9.0.1 is the name of my profile

These 2 links go into more depth if you are interested.

Don't do this like one of the links say to do.

firefox -no-remote -CreateProfile firefox-3.6

That creates a profile called firefox-3.6 like you would expect but it puts profile in the firefox directory instead of creating its own separate directory. So in this case it would be in /home/bob/.mozilla/firefox/ instead of /home/bob/.mozilla/firefox/firefox-3.6 like you would expect.

I've been using this technique for several iterations of Ubuntu.

Lately, however, I notice that whenever I start any profile that isn't default, even when I've specified the profile in the command line (using the -P option), I still get the "Choose User Profile" dialogue window (and even when I've checked off the "Don't Ask at Startup" option). Is this annoyance a bug?
