Sorry for the really dumb question. I've been using elementary for a day now and am trying to copy over the folder for an extension to the Firefox extensions folder (which I finally found). Unfortunately, when I try to do so it tells me that there is an "Eror while copying," and that "The folder "[email protected]" cannot be copied because you do not have permissions to create it in the destination." Being the only user on the OS I'm the Admin, yet can't figure out how to be allowed to copy files over to folders with that little lock on their bottom right corner. I've yet to learn my way around Terminal commands, so I'm wondering if there's a simple GUI option for this that I'm not noticing. Again, sorry for the really basic question.

Try running files as an administrator (root) by right clicking Files and clicking Open Files As Administrator


It should be opened as administrator now.

  • Mine doesnt show a run as administrator
