When I try to move the new firefox icon into my OSX applications folder I get a message telling me I don't have permission. How can I get the new version of Firefox into my applications folder?

I downloaded the new version of firefox for Mac OSX. I dragged the firefox icon over my applications folder. A message window asked if I wanted to replace an older version of the application. I clicked "yes". Another message window popped up and said I did not have permission. What now?

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.

Download a new copy of the Firefox program and save the DMG file to the desktop

  • Trash the current Firefox application to do a clean (re-)install
  • Install the new version that you have downloaded
