Recovering old data

more options

My laptop crashed and I had to format my hard and install new windows.

I have kept my passwords database files, which uses to be key3.db and key4.db along with logins.json and logins-backup.json files from my old use with me separately...

But the new Firefox folder didn't create these files anywhere where I could replace them with my files to get my stored passwords back.

Please help me restore my data from these files onto my new Firefox so I can get my stored passwords back.

This didn't help much.... But I got my passwords anyways ... I installed the Firefox version 68. And copied the files in it's user. ->local app-> Mozilla folder....

And that version picked up the passwords.. the problem was the newer versions had probably become incompatible with these files.
