in our PCs the Adobe Reader is installed (also as a firefox plugin). We
discovered that when I set, in the Options->Applications, the PDF to
"built in viewer", at the next restart this setting is reset to "Use
Adobe Reader (plugin), and remains this at ever boot, even I change it...
I found that, maybe, it's CCK2 fault. The offending code is this (file
CCK2.jsm)
if (i == "plugin.disable_full_page_plugin_for_types") {
if (!config.preferences[i].userset &&
!config.preferences[i].locked &&
!config.preferences[i].clear) {
if (Preferences.get(i) == "application/pdf" ||
!Preferences.get(i) || // firstrun
config.upgrade ||
config.firstrun) {
Preferences.set(i, config.preferences[i].value);
continue;
}
}
}
This piece of code causes, at ever Firefox restart, the reset of
application/pdf setting. If the user has Adobe Reader installed, this
settings is set to "Adobe Reader (in Firefox)". If the user tries to
change it to built in pdf reader, at next restart this settings returns
to Adobe Reader.
Commenting the above code fixes this issue.
