Description
Activity
Yes, the
rmakes it a raw string.Can you paste the location of your Firefox installation?
Can you also confirm ifnss3.dllis present in that directory?Can you also run
firefox_decrypt.py -vvv(make sure to remove your password from the output).Okay cool, I have firefox in the default location of "C:\Program Files (x86)\Mozilla Firefox" and can confirm nss3.dll is located there
This is the output I get,

In particular your Python 2.7 is probably 64bits while your Firefox is 32bits. These have to match.Can you confirm by checking your list of installed programs or following these instructions.
Reacted by I2obiN and Philipp WabnitzYep turned out it was Python 2.7 64bit, thank you for your help really really appreciate it :)

[-]Unable to find nss3.dll on Windows[/-][+]Unable to find nss3.dll on Windows (Python 64bits, Firefox 32bits)[/+]on Feb 3, 2017 Glad it works now. You are welcome.
Reacted by I2obiN@unode Why does the version of Python have to be the same as the version of Firefox? Is this because 32-bit python would be trying to load 64-bit dll?
@Ike-Clinton it's a limitation. Not versions but architecture.
Trying to get this to work on Windows, the script can't seem to find the nss3.dll
The path to the firefox directory for Windows in the script is:
line 186 -- firefox = r"C:\Program Files (x86)\Mozilla Firefox"
Is that 'r' supposed to be there?
