Okay, a password cracker is not going to help here since you already know the password, so cracking it is pointless. What you could try doing is looking in your shadow copies for an older, working version of the key4.db file. That file is in your Firefox profile folder and it stores your passwords.
Do this verbatim as I write this.
Download and install Everything.exe. Downloads - voidtools
In Everything.exe look for key4.db. There may be a bunch, but the one you're looking for is in the pathIt's in that profile folder. Right click the key4.db and open its path withen Everything.exe. Now copy and paste the key4.db file to your desktop for safe keeping.Code:C:\Users\"your username"\AppData\Roaming\Mozilla\Firefox\Profiles
Now do the same thing and look for cert9.db. It's in your Firefox profile. Copy it to your desktop for safe keeping.
Those two files are responsible for your passwords.
Run ShadowCopyView. https://www.nirsoft.net/utils/shadow_copy_view.html
Find an older shadow copy and click on it in the top box. They are listed by date. See my image.
Now in ShadowCopyView search for your profile in the bottom box after clicking on an older shadow copy. You have to double click C drive and go all the way through to the users folder, etc, etc. The same path as was in Everything.exe. You are looking for the two files key4.db and cert9.db. When you find each one, right click and copy them to a folder on your desktop. DON'T copy directly to the desktop otherwise you'll over write your backups.
Now once you have found older copies of key4.db and cert9.db, paste those in your current Firefox profile replacing what is there.
If all done right, hopefully your master password will work. If not, you may have to use an even older shadow copy.
