Hello all, I am trying to install Firefox portable on my MacBook and it constantly gives me this error message when I go to start it up:

"Your Firefox profile cannot be loaded. It may be missing or inaccessible."

I have googled the heck out of this issue and have tried every single solution I could find for the past 3 hours and I have had no luck at all.

I tried installing Firefox portable on my old MacBook, and even on a completely different computer it still is giving me this error. So it seems to be a compatibility issue between the MacBook and Firefox portable.

I would really like to begin using Firefox portable and I would appreciate it if someone can offer a possible solution to the problem I am experiencing. Thank you!

How are you running it on OS X? The Firefox from PortableApps is for Windows or Wine:

If you are running Wine and it doesn't work correctly, please try the PortableApps forums to see whether there is a known issue, or they can provide other configuration guidance:

Thank you for your reply.

I downloaded it from here: http://www.freesmug.org/portableapps:firefox

I suspect that dmg is too old now. Firefox 4 also has openly disclosed security vulnerabilities, so I recommend not bothering with that version.

That is a shame to hear, so there is no current support for Firefox portable on Mac?

Mozilla doesn't create portable versions, those are all unofficial. Why do you want a portable version instead of the normal version??

By normal version I mean:

I figured out a solution to the problem.

I download Firefox portable and drag it into the file I want it to be in, and then try to open it. I get the error message that says "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

I then rename the application file, re-download Firefox portable, drag it into the same file directory and select the option to "merge" it with the first file that will not work.

The second file that I merge works with no issues. I tried this 10 different times, and for some reason, only when I re-download Firefox and merge it, then it will always work.
