I'm trying to install Tabbrowseing extension on my Mandrake Linux machine and the terminal gives me this error

*** loading the extensions datasource
*** getItemProperty failing for lack of an item. This means getResourceForItem failed to locate a resource for aItemID (item ID = http://ftp.moz illa.org/pub/mozilla.org/extensions/tabbrowser_preferences/tabbrowser_preferences-1.1.1-fx.xpi, property = disabled)

It then got hung up and then I said to not uninstall it and it gave me...

*** getItemProperty failing for lack of an item. This means getResourceForItem failed to locate a resource for aItemID (item ID = http://ftp.mozilla.org/pub/mozilla.o...-1.1.1-fx.xpi, property = installLocation)

I then tried adblock

I then quit and restarted and got this

What version of Firefox? Are there any updates available?

I got the same crap before I updated firefox whenever I'd try to install an extension. try doing the following then install your firefox extentions, update via urpmi and if you have not set up urpmi go to http://easyurpmi.zarb.org/ if your a newb follow these steps:

become a superuser (NOT login as root!) type su then your root password
then type urpmi mozilla-firefox

1.0 and really doubt it just DL it today.

I dont think adblock has been updated for the newest firefox 1.0 if thats any help. Oh and tabbed browsing is automatically supported, its under prefs somewhere with "open new windows in a tab"
