My Samsung Galaxy Note 2 just updated to Android 4.2.1 and Adblock Plus had the same issue w. proxy.
After some searching I found that the proxy needs to be set separately for each wifi network you use. The proxy settings are hidden under settings -> WiFi -> [the network's name].
I found the following instructions online that worked for me:
Go to Settings > Wireless & networks. Long press on the name of the network that you need to add the proxy information to. When the popup box opens tap Modify Network and a new box will open. On the bottom left there is a check box that you need to check labeled Show advanced options. That will then reveal the Proxy settings and the IP settings options. Change the Proxy drop down from None to Manual. You will then need to scroll down a little bit and enter in your proxy information. Hit save when you are done, and then you’ll want to test it out to make sure it’s working.
HTH, Henk
