I have installed Firefox 4 in my Debian Testing installation from Launchpad PPA. It is quite stable and I have decided to use it instead of Firefox 3. Most of the addons I used is compatible with Firefox 4 by now. However, the version of Greasemonkey available in Mozilla Firefox Addons Site is not compatible with Mozilla Firefox v4 latest build. To install the latest nightly build of Greasemonkey, I went to Greasemonkey Nightly Download and installed it. However Greasefire is not available, we can install userscripts directly from Userscripts website for now.
[SOLVED] Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop.
I was trying to run Oracle Virtualbox in my Debian testing installation in which I have just installed Ubuntu Natty Kernel from Ubuntu repositories. I got an error followed by a dialog prompting me to run: /etc/init.d/vboxdrv setup as root.
