Where did Synergy+ go?

Synergy+ and Synergy have now merged! We'll still be using the old synergy-plus source code repository and mailing lists (there's no reason to migrate away). A bit of history for the newcomers... Chris Schoeneman created the original version of Synergy, but temporarily stopped development in 2006. Since the demand for updates was so massive, Synergy+ was started by Sorin Sbârnea and Nick Bolton in 2009 to provide support and bug fixes. While maintaining version 1, we are also working on version 2, which will see more stable support for newer operating system versions.

Upgrade Firefox in Ubuntu 10 to Firefox 4

Source: http://ubuntuforums.org/showthread.php?t=1712247

sudo add-apt-repository ppa:mozillateam/firefox-stable
sudo apt-get update
sudo apt-get upgrade or sudo apt-get install firefox ubufox

This repository provides the current mozilla release of firefox, in this case Firefox 4.0.

Bonus: I have seen others complain, and so have I, that the ubuntu language packs get stuck on firefox, are not compatible with 4.0, and are just useless.

To remove these you can remove the langpack directories (using root privileges) from
/usr/lib/firefox-addons/extensions

cd /usr/lib/firefox-addons/extensions
sudo rm -rf *langpack*

Please keep in mind this may be removing more than just the old 3.6 language packs. Please be careful and understand what you are doing before doing this.
