Tor Firmwares Not Working Now?

@wellnw Okay but maybe this is not best solutions. I see in thread (Mt300n-v2/tor Newer FirmWare? - #4 by ponzi1) @Johnex saying v3.100 use Tor again. So is not necessary for me to use old firmwares with Tor. Do you agree? 3.100 have Tor option when I click little button on router?
