Help please! I'm not tech savvy and I accidentally deleted my Firefox profile.

I was trying to fix my Firefox high CPU issue and followed the advice below. I didn't realize deleting my profile would mean losing everything. Is there a way to restore my old profile? I didn't delete the files from my old profile.

I would greatly appreciate any advice to help fix this. I'm on Windows 10 Pro. Thank you!

"Run" command: firefox.exe -P I deleted my only profile “default” I choose “Don’t delete files” Then I created a new profile

If you chose to not delete the files/folder, they might still be where they were.

Type about:profiles<enter> in the address bar. How many profiles are listed? How many should be there? Also, open the profile folder in your file explorer.
