installing firefox 3.5

You can get the "ordinary" Firefox 3.5.1 by using the script called Ubuntuzilla from
here: http://ubuntuzilla.wiki.sourceforge.net/

Page down to "Installation". I have a 32 bit machine so the operations are - download the .deb, right click it and install, then run the command (in a Terminal):ubuntuzilla.py -a install -p firefox

and answer the questions...

sudo apt-get install firefox-3.5

will install 3.5 side by side with 3.0.11

3.5 is a seperate app to 3.0.11 in Jaunt but is a true upgrade in Karmic. You can uninstall 3.0 without consequence, you will need to run:

sudo mv /usr/bin/firefox /usr/bin/firefox_old; sudo ln -s /usr/bin/firefox-3.5 /usr/bin/firefox

to save issues with apps expecting the /usr/bin/firefox program.

  Hi arochester, actionparsnip - My linux experience has just begun (about a month back) and I have no clue about operating in this environment (and I am making best endeavours...). I am amazed at how quickly my query was answered - thanks to guys like you.
     @arochester - (1) what do mean by "ordinary" firefox?
                             (2)My firefox version has this to say : Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.12) Gecko/2009070811 Ubuntu/9.04 (jaunty) Firefox/3.0.12. Is there any need to upgrade this and is there anyway this could be done?
                             (3) What is your advice/opinion on wheather I should continue with present browser or do any changes?

      @actionparsnip - hey! those commands sure sound greek to me! but hey, what are these commands and how/where can I learn about these commands? for example, when you say run some command, is it to be done on the terminal? Sorry, these might sound very trivial to you but for a beginner like me it is difficult. Thank you!

The commands are to be ran in the terminal. There are guides aout the commands either online or in the manual pages on your own system,

try opening a terminal (ALT+F2, type gnome-terminal, press enter)

man mv

You now can read the manual pages for the move command

Everyone is new once but as you use the system you will see how fun and rewarding it is to use your system and getting stuff running.

FYI.

ln -s makes a symbolic link to a file. (its a lowercase LN and nearly ALL linux commands are lowercase, Linux is also VERY case sensitive) This is like a shortcut but both the file linked to and the link itself are seen as the same thing. They also have other powers if you link a folder but do not concern yourself with that right now, just get familiar with the system

1) The "ordinary" Firefox is just badged "Firefox" and not "Shirotoko"

2) In Ubuntu you cannot normally update from the Browser and have to wait for the Repository. But you can update with Ubuntuzilla by opening from a Terminal with the command :sudo Firefox

do not run sudo firefox
sudo is for command line commands only:
e.g. mv, cp, ln, apt-get
gksudo is how to CORRECTLY run GUI apps:
e.g. firefox, nautilus, dolphin, leafpad

You will ruin file ownerships in your home directory if you use sudo for gui apps as sudo does not setup the environment correctly and is why gksudo exists. Here is exactly what will happen if you use sudo for gui app. I keep this question handy to highlight when I see people advising sudo for GUI apps.
