I've found that running: $ sh -x iceweasel -install-global-extension /root/dom_inspector-2.0.0-fx +tb+sb+sm.xpi
the script iceweasel ends executing: exec /usr/lib/iceweasel/firefox-bin -a firefox -install-global-extension file:///root/dom_inspector-2.0.0-fx+tb+sb+sm.xpi that does not install anything on /usr/lib/iceweasel/extensions/ but if I run: $ /usr/lib/iceweasel/firefox-bin -a firefox -install-global-extension /root/dom_inspector-2.0.0-fx+tb+sb+sm.xpi the extension is installed, note that I have only removed file:// from the path to the extension. some info on my system: $ cat /etc/debian_version lenny/sid $ uname -a Linux browser 2.6.26-1-686-bigmem #1 SMP Thu Aug 28 12:47:07 UTC 2008 i686 GNU/Linux $ dpkg --status iceweasel Package: iceweasel Status: install ok installed Priority: optional Section: web Installed-Size: 3656 Maintainer: Eric Dorland <[EMAIL PROTECTED]> Architecture: i386 Version: 3.0.1-1 Replaces: firefox (<< 2.0+dfsg-1), iceweasel-gnome-support (<= 3.0~b5-2), mozilla-firefox Provides: www-browser Depends: fontconfig, psmisc, procps, debianutils (>= 1.16), libc6 (>= 2.7-1), libgcc1 (>= 1:4.1.1), libglib2.0-0 (>= 2.12.0), libgtk2.0-0 (>= 2.12.0), libnspr4-0d (>= 1.8.0.10), libstdc++6 (>= 4.1.1), xulrunner-1.9 (>> 1.9~rc2-5) Suggests: xulrunner-1.9-gnome-support, latex-xft-fonts, xfonts-mathml, ttf-mathematica4.1, xprint, mozplugger, libkrb53 Conflicts: firefox (<< 2.0+dfsg-1), iceweasel-dom-inspector (<< 3.0~b4), mozilla-firefox (<< 1.5.dfsg-1) Conffiles: /etc/iceweasel/profile/bookmarks.html 5268a062e398d7c991f16155159088a3 /etc/iceweasel/profile/localstore.rdf ea03cc19c2a3f622fa557cd8ea9da6eb /etc/iceweasel/profile/prefs.js 99940ecd258d83b3355ab06fca0ffddb /etc/iceweasel/profile/mimeTypes.rdf 69cdcb7e0209f2e9d29000ee1c0ee2f0 /etc/iceweasel/profile/chrome/userChrome-example.css 4788fdaa51b0a238cb21f5c2877ef06d /etc/iceweasel/profile/chrome/userContent-example.css d3765c7d2de5626529195007f4b7144a /etc/iceweasel/iceweaselrc a7f1bcffd6febdb02e86652a60ebfd16 /etc/iceweasel/pref/iceweasel.js f1bcbce2d713f2f639a9a9db7c3ad228 Description: lightweight web browser based on Mozilla Iceweasel is a redesign of the Mozilla browser component, similar to Galeon, K-Meleon and Camino, but written using the XUL user interface language and designed to be lightweight and cross-platform. .
