Re: [tor-talk] TOR tried to take a snapshot of my screen

Hash: SHA1

I just downloaded the old version 3.6.3, the download link on
still works and leads to the file

When I use jacksum on this file, the result is

c8eb88324526d718b937b616c75d33a8 torbrowser-install-3.6.3_en-US.exe

This is another MD5 checksum than from the mentioned installer package


I was not able to download the PGP signature of the file to verify its

One of us downloaded a wrong Tor installer package ...

Best regards
