</p>Hi Duckfarmer27, could you fill in the picture for me about what you copied to where? In particular,2019-08-18T11:36:53-07:00jscher2000https://support.mozilla.org/en-US/questions/1267001#answer-1245254<p>Hi Duckfarmer27, could you fill in the picture for me about what you copied to where? In particular, I'm guessing:
</p><p>Source:
</p><p>C:\<strong>Windows.old</strong>\Users\<em>you</em>\AppData\<strong>Roaming</strong>\Mozilla\Firefox\Profiles\<em>some.folder</em>
</p><p>Destination:
</p><p>C:\Users\<em>you</em>\AppData\<strong>Roaming</strong>\Mozilla\Firefox\Profiles\<em>some.folder</em>
</p><p>Is that correct?
</p><p>Firefox doesn't automatically detect new folders under Profiles. It is only aware of the profile folders listed in these files:
</p>
<ul><li> C:\Users\<em>you</em>\AppData\<strong>Roaming</strong>\Mozilla\Firefox\profiles.ini
</li><li> C:\Users\<em>you</em>\AppData\<strong>Roaming</strong>\Mozilla\Firefox\installs.ini
</li></ul>
<p>So assuming you copied the folder into that neighborhood, the next step will be to add it to profiles.ini so Firefox can find it. There are a few methods for doing this, from manually editing the file to using the Profile Manager to create a new profile pointed at that folder. I'm not sure which is safest/fastest.
</p><p>Note: in order to edit .ini files it helps to set Windows to show all file extensions.
