Problem

When using Thunderbird i can click on a Link in an email which opens in the wrong Webbrowser. How can i make sure the Link opens into my desired webrowser instead?

Solution

Unfortunately there is not the one and only solution for this. It depends on how old your desktop profile is, how old your thunderbird profile is and how many window framworks you have used in the past. So the best thing is to try any of the following solutions in the given order.

Thunderbird Settings

1. Open yor thunderbird mail client and choose from the menu (Edit -> Preferences -> Attachments)\

2. Choose the Incoming Tab.

3. If there is some content click on the Action Field for the HTTP and HTTPS Content Type and choose your desired browser.

   • 

mimeTypes.rdf

The mimeTypes.rdf file contains information which are used to open external content. Existing entries can be adjusted (see above) but unfortunately, there is no way to add new file-type associations in the preferences window.

To add an entry for a scheme that does not appear in the list (e.g. “http” or “https”), use the following process:

1. Open the configuration editor (about:config) which can be accessed through Edit -> Preferences -> Advanced -> Config Editor....

2. Click on I'll be careful, I promise!.

3. In the search pane enter network.protocol-handler.warn-external

4. Change network.protocol-handler.warn-external.<protocol> to true for each of the protocols that you wish to configure by double-clicking on the preference. (e.g. change network.protocol-handler.warn-external.http to true to configure the program for http URLs).

5. Click on a URL in an email in Thunderbird. Thunderbird will prompt for the application to use to open the link. Select the desired program and check the option to remember the selection.

Regardless of the Desktop you use (KDE, GNOME, etc.) you need to change some Settings in the GConf repository with the GNOME configuration tool gconftool-2. The reason is that Mozilla uses GTK+ which in turn is linked to GNOME.

• Open a Shell as a User.

• Check the http, https Settings in the GConf Repository. They should either contain the gnome-www-browser (as showed below) or maybe a specific Path to an other Webbrowser (sometimes also a link to some specific firefox version).

gconftool-2 -g /desktop/gnome/url-handlers/http/command
gnome-www-browser "%s"

gconftool-2 -g /desktop/gnome/url-handlers/https/command
gnome-www-browser "%s"

gconftool-2 -g /desktop/gnome/url-handlers/http/enabled
true

gconftool-2 -g /desktop/gnome/url-handlers/https/enabled
true

• Make sure to replace these settings (even if one contains a specific firefox version) to use the SEPP firefox wrapper.

gconftool-2 -s /desktop/gnome/url-handlers/http/command '/usr/sepp/bin/firefox "%s"' --type string
gconftool-2 -s /desktop/gnome/url-handlers/https/command '/usr/sepp/bin/firefox "%s"' --type string
gconftool-2 -s /desktop/gnome/url-handlers/http/enabled 'true' --type bool
gconftool-2 -s /desktop/gnome/url-handlers/https/enabled 'true' --type bool

• Recheck the Settings to make sure they have been set to the SEPP firefox wrapper and that these Settings are used.

gconftool-2 -g /desktop/gnome/url-handlers/http/command
/usr/sepp/bin/firefox "%s"

gconftool-2 -g /desktop/gnome/url-handlers/https/command
/usr/sepp/bin/firefox "%s"

gconftool-2 -g /desktop/gnome/url-handlers/http/enabled
true

gconftool-2 -g /desktop/gnome/url-handlers/https/enabled
true

• Even if the settings should be immediately available it is advised to close thunderbird and firefox and then reopen them again.
