Is there a way from where I can restore my profile from a back-up that I took from a folder (e.g \Local Settings\Application Data\Mozilla\Firefox\Profiles\)

anuraggarg04

Before re-installing Firefox 19, I mistakenly took backup of my profile from a folder - C:\Documents and Settings\garan14\Local Settings\Application Data\Mozilla\Firefox\Profiles and not from C:\Documents and Settings\garan14\Application Data\Mozilla\Firefox\Profiles.

While installing, I selected "Delete the old profiles" option and I don't see any old profile folder under C:\Documents and Settings\garan14\Application Data\Mozilla\Firefox\Profiles.

However, I have a lot of important data saved under that profile which now has got deleted.

Is there any way I can still restore the data from old profile? (P.S.: As mentioned above, I have a back-up of profile folder which resides under Local Settings folder)

I am in a desperate need for the help. Pls reply as soon as possible.

Firefox only stores cache files in the local settings location and not the files in the main Firefox profile folder.
There is no need to backup that location in local settings anyway.

The main Firefox profile folder is in "C:\Documents and Settings\<user>\Application Data" on Windows XP.

If you removed your personal data when uninstalling Firefox and do not have a backup then your only option is to use an undelete utility to see if you can recover that profile folder.

Thanks for the instant reply.

As you mentioned, I could only recover the files using some undelete utility, I tried that. Unfortunately, it could not recover since it either got permanently deleted or overwritten.

Anyways, thanks again.

i have some problem. i delete firefox profile and i cannot use mozilla right now. can you help me ? thank you

If you have deleted the Firefox profile folder manually, but left the profiles.ini file then you need to delete the profiles.ini file to force Firefox to create a new profiles.ini file and a new default profile.

It is always best to use the Profile Manager to remove profiles.
