It drove me mad too.
Code:
sudo medit /usr/lib/firefox/mozilla.cfg
Comment out line #3 with a
# The file should look like:
Code:
pref("startup.homepage_override_url", "");
pref("startup.homepage_welcome_url", "");
#pref("browser.startup.homepage", "http://navigatrix.net/nx0.5/");
pref("extensions.maf.other.displaywelcomepage", false);
pref("browser.rights.3.shown", true);
pref("extensions.dta.version", "2.0.10");
Save and exit. Select your startup options through the Firefox browser
Edit> Preferences> GeneralI don't understand what's going on when you Drag'n'Drop with the File Manager (PCManFM). But I think it's a permission 'thing' and
cp will give you the same results.
I set up two PCManFM windows side by side and click and swish to my heart's content. If there is a permission/ownership problem I open the windows as Root drag the data over and then double check the permissions/ownership on the data in the new location...changing it if need be. Right click on a directory allows you to modify the permissions/ownership of all the files and sub-directories if you (that window) have the permission to do so.
Other just use "Midnight Commander" (
mc or
sudo mc in the terminal).
Can you describe the process you use so we can troubleshoot it?
