To change the user agent string manually so that your browser is identified as 'Firefox' instead of 'Iceweasel'. Do the following.
 * In your address bar, type {{{about:config}}}.
 * Click the "I'll be careful, I promise!" button.
 * Find the Preference Name "general.useragent.extra.firefox".
 * Right click the current value that's set for this preference and click "Modify".
 * Change "Iceweasel" to "Firefox", leaving the rest of the text alone, and click OK.
 * Check that your browser is now identified as "Firefox" by going to {{{about:}}} in your browser. The Build Identifier should resemble something like this:
  ''Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.6) Gecko/2009020409 Firefox/3.0.6 (Debian-3.0.6-1)''

What is iceweasel?

Iceweasel is a fork [from Firefox] with the following purpose :

  1. backporting of security fixes to declared Debian stable version.

  2. no inclusion of trademarked Mozilla artwork (because of #1 above)

Beyond that, they will be basically identical. (quoting Roberto C. Sanchez post in debian-devel mailing list)

How to install Iceweasel (Firefox)

Iceweasel can be installed from the Debian repository with

  • aptitude install iceweasel   #(it provides mozilla-firefox)

and native language versions such as iceweasel-l10n-fr are also available.

Nevertheless a newer backport from the Debian Mozilla team is usually preferable. The Wikipedia explains some of the terminology.

Plugin

The plugin directory is

  •  /usr/lib/mozilla/plugins

while Debian-based xul-ext plugins can be found at

  •  /usr/lib/mozilla/extensions

for more info on iceweasel plugins, refer to the plugins section of the Mozilla page.

User Agent String

IceWeasel's user agent strings (at the time of writing... ) is :

  • Mozilla/5.0 (X11; Linux i686; rv:10.0.7) Gecko/20100101 Firefox/10.0.7 Iceweasel/10.0.7 DebianWheezy (as of 2012-09-20)

  • Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.16) Gecko/20110323 Iceweasel/3.5.16) DebianSqueeze

  • Mozilla/5.0 (X11; U; Linux i686; fr; rv:1.9.0.11) Gecko/2009061212 Iceweasel/3.0.6 (Debian-3.0.6-1) DebianLenny

Some application are checking the browser's user agent string, which prevent you from accessing the site. You can change the user agent string manually or with the User Agent Switcher plugin.

You can use the User Agent Switcher plugin, then download a UA profile :

Debian-Mozilla site

This is a resource where you can get the latest iceweasel release which would eventually make it way into Debian's experimental, unstable and finally to testing and then stable. Usually the releases make their way to Debian unstable and then go downwards while the beta versions are released to experimental. Most of the aurora releases can be found at the mozilla.debian.net repo.

You can also connect with the Debian-mozilla maintainers via the mailing list as well as on IRC via #debian-mozilla on irc.oftc.net.

SSL / Secure Connection warning

The message

  •   Secure Connection Failed
      XXXX uses an invalid security certificate.
      The certificate is not trusted because it is self signed.
      The certificate is only valid for 00:16:b6:82:73:60
      (Error code: sec_error_untrusted_issuer)

Can be disabled. see : http://changetheworldwithyourpassion.blogspot.com/2008/07/turn-off-secure-connection-failed-in.html

Troubleshooting

  1. My iceweasel is consistently crashing on a website
  2. First run iceweasel without loading any extensions or plugins and see if the problem persists. This can be done by using the -safe-mode option

    MOZILLA_DISABLE_PLUGINS=1 iceweasel -safe-mode
  • If the problem goes away, then it means that one of the installed extensions is the root cause of the problem. If not then read on!
  • Create a new user and try to reproduce the problem on the new user's account.
  • If there is no problem with iceweasel on new user's account, chances are that your ~/.mozilla/firefox/ directory is corrupt.
  • In order to see if the ~/.mozilla/firefox/ is infact corrupt or not, move it to some other directory and start iceweasel again

    mv ~/.mozilla/firefox/ ~/old_firefox
    iceweasel &
  • If the problem goes away, well and good. Otherwise you can ask for help on debian-user mailing list by providing all the relevant information like "the way to reproduce the crash", "the version of iceweasel you are using", and "the distribution you are using" etc., Finally, if you are confident that it is a bug in the iceweasel package please consider filing a bug against iceweasel package.

Unsupported Browser Error

  • In order to browse websites like mlsni.net which allows firefox but not iceweasel, you'll need to change the user agent string of your browser. Look at the section "User Agent String" on how to change the user agent string.
