I migrated to new SSD. I still have my old hard drive. I copied my previous firefox data from D:\...\AppData\Local\Mozilla\Firefox\Profiles to C:\...\AppData\Local\Mozilla\Firefox\ but nothing happened.

I also have a folder named "Old Firefox Data" when I re-installed Firefox, but nothing works. Firefox sync doesn't work either.

My About Profiles Page says I have 2 other profiles besides the one currently in use, when I launch them in new browser, I cannot see my old bookmarks and passwords.

I've also changed my mobile device, so I currently cannot access my old bookmarks and passwords. Even Lockwise.

Hello. I already solved the problem. I should have copied the data from D:\...\AppData\Roaming\Mozilla\Firefox\Profiles not Local of AppData.

I have recovered all my pws, bookmarks and history.

Hello , So when you run "%APPDATA%\Mozilla\Firefox\Profiles" in the Run Command how many profiles does it show ? Also is the migrated old profile shown ?

The run command shows 5 profiles since I copied the ones from my old hard drive.
