All new Firefox 3.5 RC2 is released by mozilla team. Though it is still not recommended to install the latest release candidate from Firefox, this update is for those who can't wait to test the much hyped Firefox 3.5. Take a look
Update: Firefox 3.5 is released! Install Firefox 3.5 in Ubuntu the easiest way.

Upgrade to Firefox 3.5RC2
Update: There has been a slight misunderstanding. If you have already installed Firefox 3.5 beta, simply do the following upgradation.
- sudo apt-get update
- sudo apt-get upgrade
Install Firefox 3.5RC2
Update: If you dont have an installed verion of firefox 3.5, you need to install it altogether. Upgradation of existing stable version of Firefox wont work. If you don't want that, wait for the official release of Firefox 3.5. Otherwise, do
- sudo apt-get update
- sudo apt-get install firefox-3.5
I still strongly recommend to wait until the official firefox 3.5 release. This is strictly for adventurers ;-)

Worked great. I uninstalled 2.0 and 3.0 from my system, installed 3.5 without a problem. The glitch was I was expecting the firefox symbol on APPLICATIONS->INTERNET but saw the MINEFIELD 3.5 WEB BROWSER and ran it. It runs much faster. Thanks for the instructions on keeping up to date with Firefox.
Thanks anyways for the comment. This is the installation steps for release candidate release of Firefox 3.5. Please check the follwing link on How to install Firefox 3.5 in Ubuntu. Hope it helps. :-)
Followed instructions, now have fully functioning web browser (very fast!)
In the Applications menu it displays as " Minefield 3.5 Web Browser".
When I click on "Help", a box "about Shiretoko" displays - version 3.5.1pre
Mozilla Firefox for Ubuntu canonical -1.0
thanks
I'm using ubuntu Hardy 64 bit,I'm can error when run : * sudo apt-get update * sudo apt-get install firefox-3.5 The following packages have unmet dependencies: firefox-3.5: Depends: libpango1.0-0 (>= 1.20.5) but 1.20.1-1 is to be installed Depends: xulrunner-1.9.1 (>= 1.9.1) but it is not going to be installed E: Broken packages Any idea for my problem...?
Followed these instructions and it didn't work (firefox shortcut still launched old version). So I removed 3.0, removed 3.5, and reinstalled 3.5. Still, when I launch it from the applications menu it launches 3.0. Any idea how to COMPLETELY remove the old version?
Hi,
The new 3.5 web browser you installed is release candidate version and it will not bring any changes to the original firefox 3.0 ore installed in your system. For that you have to wait until the official release of firefox 3.5.
Now if you have installed firefox 3.5 as per above intructions, you will find a new web browser with the name Shiretoko Web Browser. You can find it in Applications > Internet. It is the Firefox 3.5 RC you just installed.
Hope you have your problem solved. Any issues, please ask. :-)
Thanks for the information.
On Hardy (8.04) I get the following error (though firefox-3.6 installs without a problem):
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help resolve the situation:
The following packages have unmet dependencies:
firefox-3.5: Depends: xulrunner-1.9.1 (>= 1.9.1~rc2) but 1.9.1~hg20090620r26001+nobinonly-0ubuntu1~umd1~hardy is to be installed
doesn't work for me.... what am I doing wrong...
There has been a slight misunderstanding. I have updated the post accordingly. Please check it. Cheers :-)
