"How to run Firefox when your profile is missing or inaccessible" article is too complicated! It's not helping me.

When I try to install Firefox on my Macbook Pro, I get this error message. But the Help articles on this topic are too complicated; there are too many options and I don't know which one applies to me.

Firefox was on my Macbook at one time but I must have uninstalled it. I did find a default profile (as instructed in the Help article) but I don't know what to do with it.

I have OS X El Capitan 10.11.6.

Thanks for any help I can get!

Are there still profile folders present if you check this in the Finder?

  • ~/Library/Application Support/Firefox/Profiles/

In Mac OS X v10.7 and later, the "~/Library" folder in the Home directory is a hidden folder.


Try to use the Profile Manager to create a new profile. On mac you need to use a Terminal window to start Firefox via a command line.

See "Creating a profile":
