Can someone other than a bot help? I tried doing this shit and it did not work.

I tried finding solutions but nothing worked. I typed in about:profile. Went to default profile. I clicked on Local Directory - Show in folder. And then pasted everything from my old firefox data folder into that. And nothing worked. Any help????

Those solutions really told you to paste everything to the Local directory????

This is wrong and I hope that it wasn't on our website.

Of course it should be the Root directory.

Can you just give a step by step guide on restoring the old profile / data back. I have the folder on my desktop named old firefox data. It has 1 folder inside that which is the profile that I originally had. Now how do I go about restoring that - step by step. No links just a step by step guide from you.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Second, open another file browser to the Old Firefox folder on your desktop. Then open the folder with the latest date, or whatever one you want to use.
