Firefox Security Best Practices

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 ?

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?

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'm little bit confused about how the upgrading or updating works. let's say im currently using ubuntu and one opened app which is firefox and im updating the system. after the upgrating is done im still using older version of ubuntu and firefox without any trouble. how is this possible. am i currently working on the programs which have loaded to the RAM?as far as i know if we run a program the whole thing is not loaded to the RAM therefor i think it's not possible to work that fine on the RAM without loading from the hard disk. im glad if any one can explane me this.

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.

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?

After install linux and configured a user to what I want (e.g.
Desktop settings, Firefox settings etc.) - how can I copy this entire setup to a newly create user?

Appreciate any advise.

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!

When I went to check my email this morning, there was a new (gigantic) ad bar at the top of my gmail page. I tried to see if there was any mention of it on google, and noticed that an even more gigantic ad bar appeared at the top of each search result. The ad bar has "ad by: Media Player" in one corner, but no option to close it. I've restarted my computer, and checked to make sure my system updates were current. I've scanned my home directory with ClamTK, and nothing comes up. I've tried to download a free trial of Bitdefender (I thought this was free, but it isn't showing up in the package repository any more, so maybe not?) but whenever I try to access the Bitdefender home page or the home page of any other antivirus scanner, I get a giant malware-y looking ad page that says "YOUR COMPUTER MAY HAVE A VIRUS" with a phone number to call for help. I have not called the number. I'm very concerned now. I want to do a full system scan, but ClamTK doesn't appear to have that capability, and I don't know how to download another antivirus program safely with the ad blocking my access to the antivirus websites. Can someone help me please?

I'm running Mint 13 Maya/Cinnamon. I'm using Firefox as my browser. I did check to see if there were other reports of this problem with Firefox or Google, but couldn't find anything current.

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?
