last night i reset firefox in order to fix a software error. all of my data is still connected to the browser and i have no problem opening my installed addons and bookmarks. my profile folder is completely missing. i tried to open it from the open folder button in about:profiles and about:config pages. i got the same exact location is missing error message every time. i went into my appdata folder and checked local, locallow and roaming. there was only one mozilla folder in locallow and it was completely empty. about:profiles says that my current profile, the default release one, is currently in use, but it isn't on my computer. there's not even an old data folder like some articles suggested. i haven't deleted or fiddled with anything since the reset. nothing is in my recycling bin. i've reread every article at least three times and none of them have solutions i can use because the mozilla folder is COMPLETELY MISSING.

Refreshing Firefox {web link} is a LAST RESORT ! !

Refreshing Firefox -- easily fix most problems

If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks and open tabs. Everything else, like user settings and add-ons, are removed. Note: Refresh saves your old profile to the desktop in a folder called Old Firefox.


Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.

What software problems did you have to consider using the refresh feature in Firefox ?

Do you have an "Old Firefox Data" folder on the desktop that could have old profile ?

The main profile folder is always in AppData\Roaming, so if there aren't profiles in this location then something went wrong with refreshing.

Firefox uses two locations for the Firefox profile folder. One location for your personal data (e.g. bookmarks) and another location for temporary files like the disk cache.

Location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>

Location used for the disk cache and other temporary files (Local Directory on about:profiles).

  • C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>
