`TBB 3.5 - lot of Unable to connect errors` TBB user [reports](https://lists.torproject.org/pipermail/tor-talk/2014-January/031967.html): ``` Additional info: - I am on 3.5.1 now and have the same issues - it seems thing work fine if I use the default torrc file What I change is to add about 20 MapAddress lines to block ad servers. I use the same list on 2.3.25 and there it causes no problems. ```
