Hi there I installed Ubuntu a few minutes ago (i'm very new on Ubuntu) and whenever I want to open Firefox I get an error which starts with "could not initialize application security ...".
Also when I try to restart Ubuntu it stops and I have to shut-down manually with the power button. During the shutdown there is a message
Killing all remaining processes --> fail
I will be glad if you can help me and thanks anyway
It sounds like you have a corrupted Firefox profile to deal with this problem you will need to run Firefox profile manager to do this open a terminal open the dash and type terminal
and enter this command at the prompt firefox -profilemanager like this
and hit the Enter key
you should then see a dialogue like this
you need to first delete the default profile then create a new profile
Hope this helps
This error message can be from one of 3 problems:
1) You are out of hard drive space.
2) Incorrect permissions in your mozilla / firefox directory ~/.mozilla
3) A corrupt database, cert8.db
So while many people advise you simply delete your firefox profile, that does not really address the problems and you will loose your customizations (bookmarks).
So, first , check to make sure your home or root partitions are not full. If they are, make more space.
Second, make sure your permissions are correct (this will fix any permissions problem in your home directory, firefox or otherwise).
sudo chown -R your_user:your_user /home/your_user
Last, if that fails, delete cert8.db
rm -f ~/.mozilla/firefox/*.default/cert8.db
For details see http://kb.mozillazine.org/Could_not_initialize_the_browser_security_component
One of those 3 steps should fix the issue without deleting your customizations.
Try this
sudo chown -R $USER:$USER ~/.mozilla
Firefox and its profile does a little bit more than most people think i found out today if you care to look.
The android version of Firefox without any plugins is listening in to DLNA broacast messages from devices like XBoxes and Samsung Smart TVs and then making a UPNP request to the devices to recive XML data back from these devices.
In my case this not only includes the make and model of the TV but also the serial number and its not like my simple android device can stream to the TV or play XBox games.
Shown below is both the request and reply I captured with some of the data replaced using XXX and I also had to tweak the HTML tags in the XML so it would post.
