On my Gentoo Linux machine, I installed the Gentoo mozilla-firefox-bin-1.0.6 package. This is Firefox 1.0.6 the way it has been compiled by mozilla.org. It is installed in system directories (/opt/firefox) to which the normal user of course has no write permission.
In a new profile (ie. one with no other extensions, themes or customizations) I tried to install Adblock_Plus_0.5.8+_july19.xpi. After clicking on the link, I quit Firefox and restarted it. In the terminal from which I started firefox-bin, I get this error:
- Code: Select all
$ /usr/bin/firefox-bin -ProfileManager
(Gecko:5533): Gdk-WARNING **: gdk_property_get(): length value has wrapped in calculation (did you pass G_MAXLONG?)
(firefox-bin:5533): Gdk-WARNING **: gdk_property_get(): length value has wrapped in calculation (did you pass G_MAXLONG?)

This item will be uninstalled after you restart Firefox.
Seems Adblock Plus won't install.
What am I doing wrong and how do I get it to install?
