My TB3 insists on opening all URLs in Firefox. I've moved on to Chrome as default browser and would like all my links to open there.

Have done/checked:

1.
Chrome is set as my default web browser (Prefs->Preferred Apps)

2.
The Gnome config seems indeed to be set to use Chrome.
anlag@casper:~$ gconftool-2 -g /desktop/gnome/url-handlers/http/command
/opt/google/chrome/google-chrome %s

(same with https)

3.
Went into TB's about:config and looked for relevant settings, found nothing but another thread on here suggests network.protocol-handler.app.http should decide which browser to use. This didn't exist; I tried creating it and using both the full output of gconftool-2 above, and simply "google-chrome" but neither makes a difference.

4.
Went into TB's Preferences->Attachments and looked for settings for http/https, also going on another suggestion on here. I have neither entry in that list (only JPEG) and see no way to add anything.


What can I do? Thanks in advance.
