How to Install Firefox 4 in Ubuntu 10.10, 10.04 and 9.10

What's that cool bar on the bottom, with menu, quick launch, and notification area ?

thats the tutorial

Firefox Just keeps getting better and better.

Yea, it crashes out of the gate. Can't get the page to load at all. Don't bother, it's obviously not ready for prime time. I run 10.04LTS.

BleedingEdge installs Firefox 4 (Minefield)

excellent...thx for ubuntu and firefox

what's that dock thing called?

I put it on my system and it crashed everything and I had to reinstall my entire system. Thanks a lot.

Moron or troll ... moron or troll ... I'm going troll. For you to crash your system completely doing this is harder than climbing Mt Everest in a single day in the buff.
Like any pen, a poison one can leak and it is your fingers that will be stained.

Another * ... hunted down

Thanks. its works.

Seriously? Alt-F2? For EVERYTHING? You are not really helping by babying. Run a terminal application(it won't bite I promise) , then enter in the commands:

sudo add-apt-repository .......
sudo apt-get update

Awesome.. finally got to install firefox 4 on my ubuntu..
cheers

Just great so far, can't complain, seems fast and efficient, haven't struck any bugs yet. Seems to run well on 10.10

What about my addons that I had working with 3.6.13? Should I assume that the addons will have to catch up wit this?

Yes, most add-ons are begin updated for Firefox 4 as we speak. Check out our up-to-date Firefox extensions section for the latest add-ons:

What about language packages? There are cases when these Firefox uppgrades are successful but only with english versions.

Just followed the exact directions on my Ubuntu 10.10 64bit system. Worked perfectly. It even picked up the persona that I had applied to my 3.6 version of firefox. My FoxyProxy plugin, y-slow, web developer toolbar all worked fin. Firebug did not but that is to be expected on day one of the release.
AS for the postest decrying the use of 'alt-f2', eh - it works and supports the lowest common denominator. If you are familiar with the command line adapting the instructions on the fly is easy, however if you have no idea what a command line is, then that should not stop you from using firefox-4.0.
What makes me laugh is the trolls/MS plants who write comments about how they needed to re-install their entire system afterward. THEY ARE JUST TROLLS. Ignore them. This is a safe process, and unlike windows systems, the browser is in NO WAY connected to the operating system so it simply cannot take down the computer and require a reinstall.
Do not be afraid of the angry jealous man my friends and fellow Ubuntu users, there will always be haters, but they have no bite and can be safely ignored
What will be interesting is seeing how soon this browser makes it into the official Ubuntu 10.10 repositories, and how long it takes firebug to catch up.

Thank you! Thank you very much!!! Imagine this: there are many "how to" installing the latest version of Firefox in Linux, but any of them had told us that Firefox 4 for Linux is called "Minefield"!!!!! Thanks for that, because many hours ago I had installed this browser and I didn't know!

sir, I m vivek..
I understand your steps but this will result in downloading of firefox 4.0b12.tar.bz2....
I want to ask how we can install it if we are having in a disk as I have already downloaded it from windows 7 and burned in a disk..
Plz give your suggestions for installing it from a disk..

Why can't the Linux community issue instructions like this for all software installations?

I'm a Windows 7 user by choice because it is so difficult to install software on Linux!

Having said that, Ubuntu 10.10 with wubi is a dream to install from a windows environment but I do have difficulty installing some software especially if I have to compile the source :o(>

I typed "Y" and it's not there...in my apps.

after upgrading Ubuntu10.10 to Ubuntu11.4
& installing compiz my ubuntu get bug.....

well, in the terminal it tels me thar it's impossible to find the "firefox-4.0" package.. i'll keep trying! thanks!

helpful... thanks!....

worked on ubuntu 10.04 thanks :)

Love the instructions--easy to follow. I was a little surprised to end up with Firefox 8.0x from the Nightly channel rather than FF 4, but it's working a treat, so no problems on that account.
Many thanks.

Thanks for sharing such useful information
Keep it up.!!!!!!

Thank you very much!! totally helpful.. works great!!!

2nd December 2011 .... This actually downloads a 'nightly' build of Mozilla/Firefox, (not minefield) which, while working, has incomplete generic folder icons and html icons in your bookmarks. All bookmarks are migrated from my previous firefox 3.6.8. I was hoping tho get the updated version of Adobe flash player pre-installed with this browser download, but that was not the case.

Have done everything step by step, when entering
sudo apt-get install firefox-4.0 in to the terminal command line, click "run in terminal" , click run, enter password and all I get is "transferring data from s7.addthis.com" and nothing happens after that. Why can't this stuff be programmed to work correctly?
