Running Iceweasel-5.0 And Iceweasel-4.0 Together On Squeeze

I'm running iceweasel-4.0 installed from http://mozilla.debian.net/.
Related packages are :
iceweasel 4.0.1-1~bpo60+1
xulrunner-5.0 5.0~b2-1~bpo60+1
libmozjs5d 5.0~b2-1~bpo60+1
If you want to try out iceweasel-5.0 and keep iceweasel-4.0 as well do the following :

Add the following line to your sources.list :
deb http://mozilla.debian.net/ squeeze-backports iceweasel-5.0
and run as root apt-get update .
We only need to download the deb package to get iceweasel-5.0, we don't install it ( otherwise iceweasel-4.0 will just be upgraded ). As root run :
apt-get install -d -t squeeze-backports iceweasel
This will download package iceweasel_5.0~b2-1~bpo60+1_amd64.deb in my case. You can find it back inside /var/cache/apt/archives .

As root run the following commands :
mkdir /usr/local/iceweasel5
dpkg-deb -x iceweasel_5.0~b2-1~bpo60+1_amd64.deb /usr/local/iceweasel5/
ln -s /usr/lib/xulrunner-5.0 /usr/local/iceweasel5/usr/lib
ln -s /usr/local/iceweasel5/usr/bin/iceweasel /usr/local/bin/iceweasel5

To verify :
which iceweasel5 gives :
/usr/local/bin/iceweasel5

Run iceweasel5 -P and create a new profile.

Make a shortcut to run iceweasel-5.0 :
iceweasel5 -P "profilename" -no-remote

Multifox Extension : Sign Into Multiple Same-Service Accounts

Multifox is an extension that allows Firefox to connect to websites using different user names.

Once you have installed the Multifox extension there are three ways to access it :
Menu : File > New Identity Profile
Tabs Context Menu : rightclick any tab > Open in a New Identity Profile
Context Menu for your bookmarks : Bookmarks > rightclick any bookmark > Open in a New Identity Profile

Any of the three will cause a new and separate window to open. Counting starts from 2 : notice a blue square with a number at the end of the Address Bar.
Logins made in windows with different numbers are isolated.
Clicking on any of the blue numbered squares will open a drop-down window with basic information about that particular identity profile.

Kernel 2.6.38 in Squeeze Backports

Backports are recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates) in a stable environment so that they will run without new libraries (whenever it is possible) on a Debian stable distribution.
Add this line :
deb http://backports.debian.org/debian-backports squeeze-backports main to your sources.list and run :
apt-get update
To install kernel 2.6.38 I did ( amd64) :
apt-get -t squeeze-backports install linux-image-2.6.38-bpo.2-amd64
I needed the headers as well, but I got the message : The following packages have unmet dependencies:
linux-headers-2.6.38-bpo.2-amd64: Depends: linux-kbuild-2.6.38

Solution : just download linux-kbuild-2.6.38 from http://packages.debian.org/wheezy/linux-kbuild-2.6.38 and install it with dpkg -i . Now you can install the kernel-headers as well from squeeze-backports.

Minor Scrolling Issues Iceweasel-4

I've had some minor scrolling issues with iceweasel-4 which mostly did not draw my attention until I came across this page : http://tech.shantanugoel.com/2009/07/07/virtualbox-high-cpu-usage-problem-solved.html. Scrolling was very choppy.....
Some background : system : Debian squeeze amd64 gnome, nvidia 270.41.19 ( nvidia.com ).
apt-cache policy iceweasel
iceweasel:
Installed: 4.0.1-1~bpo60+1
Candidate: 4.0.1-1~bpo60+1
........
I've tried different gtk-styles, different window-managers, disabled all plugins and extensions, created a new profile.....no improvement....
Some others things I've noticed : running iceweasel-4 in virtualbox ( minimal gnome installation Sid ) did not have these scrolling issues.....( so is nvidia to be blamed ? ).
Out of curiosity I uninstalled the nvidiadriver and used nouveau : scrolling issues were gone...
( that was an one-time experiment ).

I tried just one more step : Added deb http://hadret.rootnode.net/debian/ unstable main to sources.list and upgraded libcairo2 from version 1.10.2-1.1~bpo60+1 ( squeeze-backports ) to version 1.10.2-6.1. ( http://hadret.rootnode.net/ )
Problem was mostly solved, but I still have some trouble on certain pages. An example this page : http://www.groupon.nl/.
Scrolling gets sticky past the middle of the page....

Next tweak I found out ( scrolling issues disappear ) was to start iceweasel with MOZ_ACCELERATED=1 /usr/bin/iceweasel
Or you can go to the about:config page and set layers.acceleration.force-enabled to true.
If you go to Help > Troubleshooting Information you will see at the bottom of the page :
GPU Accelerated Windows 1/1 OpenGL

With certain themes this tweak will make the tab animation choppy, but you can switch it off by going to the about:config page and set browser.tabs.animate to false.
