I see you copied your entire Old Firefox Data folder into Profiles, but actually, you just want the inner folder, your old profile folder. Here are the next steps:
</p><p><strong>(1) Move your old profile folder from inside the <em>Old Firefox Data</em> Folder up one level to the Profiles folder</strong>
</p><p>I'm sure you know Finder better than I do. Assuming I am guessing the folder names correctly, the <strong>yetb25at.default</strong> folder should end up next to its post-Refresh cousin, yetb25at.default-1612920550705
</p><p><strong>(2) Configure Firefox to use the old profile</strong>
</p><p>Make a note of the text after the dot on the profile folder. For example, it probably is <strong>default</strong> but sometimes it is <strong>default-release</strong>. You need the new profile name to match the old one in order for Firefox to regain use of your extensions and their data.
</p><p>Inside Firefox, type or paste <strong>about:profiles</strong> in the address bar and press Enter/Return to load it.
</p>
<ul><li> Click the "Create a New Profile" button, then click Next.
</li><li> Assign the old profile name <strong>default</strong> and Firefox should show a proposed folder name with a new random part.
</li><li> Click the "Choose Folder..." button and select the old profile folder you copy/pasted so that Firefox picks up the full old name.
</li><li> Back in Firefox, click the Done button.
</li></ul>
<p>After creating a new profile, Firefox usually makes it your default profile (for external links and the next startup). To test, scroll down to it and click the <strong>Launch profile in new browser</strong> button.
</p><p><em>Did it work?</em>
</p><p>If so, you're done.
</p><p>If not, you can close that window without affecting your regular Firefox profile and change back to the profile you started with before this post. Click the <strong>Set as Default Profile</strong> button below that profile.
