By default, Debian Wheezy installs Iceweasel (Firefox) 10.x. This can break a lot of extensions so, for those who would rather stick with version 3.x, this is how I reverted to the older version. Note that there may be alternative, ” official” method, but this is the quick-and-dirty that I came up with.
Disclaimer: this worked for me, your mileage may vary. Use these instructions at your own risk. (If you do come across any issues, please get in touch – especially if you find solutions – so I can amend this article.)
Get The Packages
At the time of writing, the current, stable, version of Debian is Squeeze – which installs Iceweasel 3.x by default. We will, therefore, make use of Squeeze packages:
Download packages appropriate for your architecture, install using
dpkg -i, in the order given above. I think this is the correct sequence to solve all dependencies. Other dependencies may be unmet due to different software configurations. Simply note what’s missing from the messages given by dpkg and find the packages through packages.debian.org.
Due to the rather onerous process of creating XUL-based extensions (and for other reasons) I am in the process of migrating to the Chromium browser. I went through this exercise because I can’t commit the time to either writing the Chromium extension or fixing the Firefox/Iceweasel one. With Chris Pederick’s Web Developer Toolbar now being available for Chrome/Chromium, my one little extension is the only remaining reason to be using Firefox/Iceweasel as my main browser.
