Oh, I solved it: xdg-mime default okular.desktop image/vnd.djvu I wonder where this information is stored, since I already had it in my local mimeapps.list. So in order to set a default program for sime filetype, one has to find it's mime type first -- which can be done by looking at /etc/gnome/defaults.list for example (and at /etc/mime.types in case ...

The problem is caused by this bug: https://bugs.launchpad.net/unity/+bug/968533 Some workarounds from the thread somewhat in order of drasticness: type about:config into the firefox address bar, set setting ui.use_unity_menubar = false Disable firefox unity plugins Install compiz config settings manager and disable the alt HUD entirely as described in How ...

I don't think so. In fact, the GPU helps to have a better video RAM memory and allows RAM to be used in other processes, instead of the integrated video processors in most of the motherboards, which spend some of RAM memory for video. Note that if you have opened a heavy adobe flash app, if would affect the performance of CPU (strongly, if you have opened ...

Updating the intel drivers using the graphics installer from the Intel Open Source Technology Centre seems to have helped with this problem. Get it here: https://01.org/linuxgraphics/downloads/2014/intelr-graphics-installer-1.0.4-linux and run in the terminal (ctrl+alt+t) with: intel-linux-graphics-installer Dashes still appear on occasion, but seem to ...

I second the Bleachbit program. It's a good alternative, but don't do what I did and accidentally check the "wipe free disk space" option. :P

Bleachbit is a good alternative for linux and will allow you to clean program clutter and system clutter to tidy up things like logs, caches and thumbnail libraries grown too huge... It can be found in the Software Centre...

Actually it worked for me several times. Hope it works for you too.

I am not sure if that is the solution. But I got this working (presumably lasts). Following my theory that everything was caused by the security update and that the "update flash plugin" was related to it I came to do the following: -Youtube finally stop working and I desperately needed some music to work. I tried to download the plugin but I couldn't so I ...

To be able to open Firefox (or even install apps) while doing the installer the first part is to select the Try Ubuntu option found as the first option in the installer: The difference between both is that Install Ubuntu will automatically start the Ubuntu installer process. The Try Ubuntu will load the Desktop and you can play around with Ubuntu, ...

You only need to type: sudo apt-get purge firefox and then type y for "Yes", and Enter That took care of everything. Firefox is now off of my computer and Google Chrome is doing a great job.

Found a reference to this bug in which comments suggests blacklisting the driver like this: echo "blacklist ar9170usb" | sudo tee /etc/modprobe.d/blacklist-ar9170.conf After reboot, it should work better. If not, remove the /etc/modprobe.d/blacklist-ar9170.conf file.

One of the features of the CCK Wizard Firefox add-on is importing CA certs. I use this add-on to create a custom add-on that includes a company CA Cert. I then package the custom xpi in a .deb on the internal repository that all the workstations get updates from. CCK Wizard EDIT: In order to package the xpi for Ubuntu, you need to create a package that ...

WinKey+Alt+Click works for me most of the times, although I'm not on Ubuntu, but on another Linux distro. WinKey is that key branded with the Redmond company logo.

I found a great solution here: http://www.trishtech.com/2012/04/disable-html5-media-in-mozilla-firefox/ Essentially you are telling Firefox to not use the HTML5 media components.

I think, but cannot prove anything, that the Europol virus on my PC came from a nosy neighbor. After re-installing Firefox, I have reasons to believe that there still was a link between my PC and his. I do not know how, I am too much of a lay man. A check with RKhunter, top and htop did not not come across anything suspicious. I ended up using the shred ...

I've found virtually all errors of this type to be solveable by running MOZ_DISABLE_IMAGE_OPTIMIZE=1 firefox in a terminal, to test if it works. If it does, I just add MOZ_DISABLE_IMAGE_OPTIMIZE=1 to /etc/environment (you would then have to log out and log back in for this to take effect from your desktop environment I think, although from a newly opened ...

Not sure if this helps, but I had a failed GPU fan, and so my computer would hang whenever I did anything which was GPU intensive (the temperature would reach 90-100 degrees and auto poweroff). Flash can be GPU intensive, are you sure your GPU is working ok?

Here is my analyze to the 4 possibible ways to record Firefox passwords listed in your question, plus a new solution (#5): Their are some notes to security in the README. It seems that it is not more or less secure then the original implementation. But for GNOME Keyring you have some options like auto-lock your keyring after a certain (idle) time. Source ...

I use Ubuntu at work, OSX at home. I can use most addons on both systems. You can download the live-cd, run that from dvd/cd or usb, startup firefox, install all addons you want, and see what works and what not.

I'm going to say both via the Software Center or the webbrowser,it depends on the add on. If you want to keep on the outside of the envelope, use the built-in add on manager. Add ons installed this way will be updated frequently, and you will get major version updates. If you prefer a bit of stability, use the ones from the repositories. They are (mostly) ...

Network traffic capturing is possible but messy. There are many applications running on my computer that communicate over HTML and they would fill a log up with their automated API handling and wouldn't reflect what I was visiting. And as you correctly say, it won't show you HTTPS. The URL is an encrypted part of the request. I would target the browser ...

For a solution that worked for me: https://support.mozilla.org/en-US/questions/965921 "Click on the help menu and select "Restart with Add-ons Disabled" and then select the reset option in the dialog box." Follow the on-screen prompts. Then restart Firefox. When you click on a magnet link the usual "Choose a program" type of dialog box appears. Browse ...
