Error : No Display Specified. Firefox On Opensuse

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 boot with Kubuntu Live CD,
I launched terminal,
go to the folder where I unpack the Firefox TAR ball,
and run ./firefox
it says Permission denied

How to solve this?

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 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!

Firefox26 is the default browser.. but it is out of date and not supported by my Google Mail.. It also will not auto update.. and I keep getting warnings about Adobe Flash version being unsafe..

I have a lot of Bookmarks which I would like to save.. before doing anything radical.

Downloading the latest Firefox 34 for Linux from Mozilla [firefox-34.0.5(1).tar.bz2] does not help it only unpacks all the files but does not begin to install anything. Trying to execute [run-mozilla.sh] the only script file.. opens it in an editor?

How to save my bookmarks and update my browser..?

Whenever I log into Hotmail (and usually when I log into Gmail) as I begin writing everything is marked as mispelled, and when I click on Language, I find it has defaulted to French.

I do occasionally work in French, and I am used to the system fefulting to whichever language I have used more recently, but since the last upgrade to 34.0, it always defaults to French. If I have started with Hotmail, it almost always taks two or three tries to change the default; with Gmail it usually catches on the first try.

I am relatively sure this is a Firefox bug, as it does not occur if I open with Opera.

Any ideas? Or should I just be passing a bug report to Mozilla?

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.
