That’s fine… and to be expected, the first command was only to back up Firefox 3 for people who’d installed it, and WILL fail if FF3 was never installed… I included it as a precaution.
Just carry on with the instructions.
thanks
now this may be a stupid question, but the next command line to download firefox 4 does nothing as I press enter, presumably because I cant download it as I now have no browser, so how do i get around that?
do i need to recover Firefox 2 first?
Enter this:
thunar ~
and tell me if there is a file called firefox-4.0.1.tar.bz2 there.
no, scrolled down the list - it is not there
OK, let’s try again:
in the terminal enter:
cd ~
then:
wget -O firefox-4.0.1.tar.bz2 "http://download.mozilla.org/?product=firefox-4.0.1&os=linux&lang=en-GB"
Remember Linux commands ARE case sensitive, so be sure to enter them exactly as shown.
It would be much better if you could copy and paste the commands into the terminal 
ok I have typed in those commands
and did it download ?
enter:
thunar ~
and see if there is a file called firefox-4.0.1.tar.bz2 there ?
Mark - it did not download and the file is not in Thunar
unfortunately my memory stick died so cant copy and paste commands - will try to get another this evening
Go to chat… top of page.
If it would make things easier… use the search bar to search for firefox then run the firefox executable (probably in the /usr/lib/firefox directory, but may be elsewhere)… that should start firefox 2
OK, I’ve just explored the Recovery DVD’s drive image, and it seems like the firefox 2 executable is located at /usr/lib/firefox-2.0.0.14/firefox
So open a terminal, and enter:
cd /usr/lib/firefox-2.0.0.14
then
./firefox
to run firefox 2.
If that works, let me know and well download the firefox 4 archive using firefox 2
another command that should start Firefox 2 is:
bash /usr/lib/firefox-2.0.0.14/firefox
If those commands dont work… open thunar with this command:
thunar /usr/lib
look for a folder called firefox-... and adjust the above command(s) accordingly.
Like I said let me know how you get on, and we’ll either install FF4, or fix the FF2 shortcut.
Mark that worked first time, so got into Firefox 2 ok. Maybe i can contact you tomorrow and have a go at installing v4 again with your guidance or at least restore shortcuts to v2 :). thanks again have a good evening
No problem… gimme a shout tomorrow then, I’m on here pretty much all the time … I’ll keep an eye out for you.
Hi Mark
managed to download Firefox4 into Thunar so can now see the file firefox-4.0.1.tar.bz2
have also copied commands into a document file so can paste them in, however the next command for extracting the downloaded still giving ‘connection refused response’ - any suggestions?
OK, problem solved in Chat…
For some unknown reason any command that started with sudo was throwing up a “connection refused” error and not completing.
Solution -
For every command that needed root privileges (ie. started with sudo) we first entered:
sudo su
and hit enter, this changed the command prompt to a root prompt, THEN entered the command WITHOUT the “sudo” prefix.
Commands that start without “sudo”, enter:
exit
to get back to a normal prompt, THEN enter the command.
if your prompt lline ends with $
it is a normal (regular user) prompt
if your prompt lline ends with #
you have root privileges.
In Summary -
If the command starts with sudo, change to a # prompt, and drop the “sudo” from the beginning of the command.
If the command DOESN’T start with sudo, make sure you are at a $ prompt.
Well I had no chance whatsoever of installing this successfully without Mark’s genius and his generous guidance, what with that ‘sudo’ bug that was throwing up all the ‘connection refused’ errors. 
Thankfully i now have Firefox 4.0.1 up and running and can now access websites that could not tolerate the vintage Firefox 2.
Thank you very much indeed.
I made installation as in instructions in first page. Two questions:
- How I know that installation is ok or that I really are using FF4, and
- Firefox icon disappeared from menu, there reads only browser, the other icons are still in their place
I’m grateful for any answer, thanks
If the Firefox menu bar ISN’t showing, right click somehere to the right of the tabs, and select “Menu Bar”
Then go to Help > About Firefox … The version will be displayed, like this -
http://linuxforums.org.uk/MGalleryItem.php?id=1211
If you are running FF4… run this command again to change the icon:
sudo sed '/Icon/ s/acs_//' -i /usr/share/applications/linpus-web.desktop
then reboot for the change to take effect.
Hi Mark
I’ll apologise immediately for my total lack of linux knowledge, the instructions you left are brilliant and very easy to use.
Just a bit of background…
My friend was having problems with their AA1 and I tried to take a look.
Having researched the problem & finding your instructions i’ve given it a go.
All files downloaded fine, all commands were entered and no errors found.
I had restarted the unit & thought i’d disable the google toolbar (opening FF in -safe-mode which again worked with no issues) & then restarted.
Hey presto eveything seemed to be working now that firefox actually opens.
wanting to test the general websites I think she uses it for, I opened facebook, bbc news etc & then youtube which promptly told me the browser was out of date.
I then looked at the version and it still shows ver 2.0.0.14
Have you any ideas of what exactly has gone wrong with the update as I seem to have the files and folders in the right place but just not the actual correct version running when selecting the browser.
I knew from the instructions that FF2 still exists as it’s still required but figured that the redirects to the new data would be using the new version.
Open a terminal, and enter these 2 commands, and tell me what happens:
cd /opt/firefox
then
./firefox
If Firefox opens… check it’s version 4 in the Help > About Firefox menu item… see my previous posting.
And don’t apologise… we all had to start at the beginning
[EDIT]
Can you also post the output from:
ls -l /opt
delta5215’s problem was sorted in chat…
We ended up backing up then deleting all the firefox profiles, creating a new one called default and re-running the:
sudo ln -fs /opt/firefox/firefox /usr/bin/firefox
command.
I’m not convinced that deleting the profiles was necessary… I’m pretty sure it was the symlink that was going wrong somewhere along the line.
