View Full Version : [ubuntu] undo trust certificate

February 14th, 2010, 05:16 AM
I had a msg pop up when I uploaded pics to facebook saying I was uploading to this site. I clicked ok before noticing that a box was checked that said something like "always trust this website". Can I go back and undo that so it comes up every time asking if I trust this website? I use ubuntu 9.04

On Firefox, go to "Edit >> Preferences >> Advanced >> Encryption >> View Certificates >> Servers. You should see an entry for facebook there. Select it and click delete button.
