Also,it is saying when I am putting the full path(and I am pretty sure I have not made any mistakes in there) "No such file or directory."

If you start Firefox from a directory then you need to use ./firefox

I use scripts like this to run multiple versions at once:

#!/bin/sh

cd /usr/local/firefox
./firefox -no-remote -P "default"

• http://kb.mozillazine.org/Using_multiple_profiles_-_Firefox

You can use the -no-remote command line switch to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously, but do not use this with the default profile.

I tried that...still getting this error

bash: ./firefox: No such file or directory.

Are you running this command in the directory where you installed Firefox (ls -l)?

Yes.In the same directory.

So, is there a firefox file in that folder?

What is the output of ls -l?

Did you check the permissions to make sure that you have read access?

Output of ls -l

I tried to make it easier to read.

(edited the previous reply, so this reply is no longer needed - c)

That looks OK to me, so starting Firefox via ./firefox should work AFAICT.

Does this also happen if you create a desktop launcher and browse to this location?

I use an Openbox desktop,so I dont use launchers.But my attempts at opening firefox are always unsuccessful.

Did you make sure that you meet the System Requirements for this Firefox version?

• http://www.mozilla.org/en-US/firefox/21.0/system-requirements/

You appear to have 64-bit Linux as the Linux builds served on mozilla.org are 32-bit.

ftp://ftp.mozilla.org/pub/firefox/releases/21.0/linux-x86_64/

My problem is solved,but could you point me to some rescource explaining the nature of this(32 bit builds giving this sort of error).

I am getting the same error. Can you please let me know how you have fixed it ?

@ubwebpc:/usr/local/firefox$ firefox
