Could Not Run Firefox From Terminal

I downloaded the firefox and extracted it using tar xjvf
And then when I try to open from a terminal
I get above error
Error : no display specified

It also default firefox 4.0b12. It opens when I click on the firefox icon and but not via terminal.

I want to open extracted latest firefox via terminal.

Any solutions available for the same.

Hi all ,
i tried to update firefox 24 to firefox 35. Found a tutorial how to install it and did
#chown -R root:root /tmp/firefox && mv /tmp/firefox /opt/firefox-latest
#ln -s /opt/firefox-latest/firefox /usr/local/bin/firefox-latest
and now run it with firefox-latest.
I had actually the both versions of firefox and with pkgtool tried to remove firefox 35 but it cant, so i uninstalled firefox 24. Now i have troubles with flashplayer. how can remove firefox 35 ?

When i doble click on some html file it gives me that error

KDEInit could not launch '/usr/lib64/firefox-24.2.0/firefox.

I can open it with right click and use "open with" option, but than i have 4 positions of firefox in context menu. How can solve this ? I currently use firefox 34.1 , installed it slackpkg.

I use Firefox 16 for my automation and it uses gconfd internally.
Is there a way to disable firefox from using gconfd. It writes a lot of data into saved_state which is leading to crashing total usage of CPU.

I have found –disable-gconf
but not sure how to compile firefox with that command


Is there a way to disable log messages from gconf?

What are the recommended best security practices for using Firefox on a new Linux system (Centos 7 in my case)? I only access the web using Firefox using my regular, non-root, account. Other than that, what Firefox and/or system settings should I enable/disable in order to safeguard my system from malware scripts, viruses, etc? Also, are there similar Thunderbird settings that should be enabled/disabled?

Thanks in advance from a new Linux user

I'm trying to move a new version of Linux into the opt file through sudo but by putting "sudo mv Firefox /opt/firefox34" AND without the 34 at the end but all its saying is "sudo: unable to resolve host name --minty fresh-- mv: cannot stay 'firefox': No such file or directory" but I'm sure I downloaded the new version of Firefox! Now I can't use the Internet!

My Firefox browser says it needs to be updated so I downloaded the file but when I open it I can't see how to update it as there are just lots of files and folders. Is there another way to update programmes I am missing?

I've just installed Arch, and Installed and configured openbox and gnome terminal. Openbox starts, firefox works, but when I try to start gnome terminal, I curser spins for a moment and then it doesnt load.

I've tried to find a resolution to this but I'm not seeing much relevant to this specific scenerio. Also, this is my first time ever installing Arch, or any distro without a graphic installer or a kickstart script. My experience is pretty basic. I've used ubuntu/mint/centos for quite a while but figured this will be a good way to get me learning.

After I post this I am going to reboot to get back to command line and look at the installation and maybe install another terminal and see if this makes much a difference.

Hello, I have just started using linux and I installed linux mint with the i3 window manager on my laptop. I am wondering how can I "theme" it so that it looks good. Right now everyhting in the terminal when I open something such as MOC is ugly and old looking... SO is firefox. How can I chnage the theme to make it more modern looking?? terminal and everything?

When someone send me a link on viber and click on it , pops up that dialog
"Service '/usr/bin/firefox' is malformatted"
How can fix this ?
I use slackware 14
