Is AdBlock Plus needed to filter everything Proxo misses?

[Graycode]

For solely ad blocking in Firefox then ABP seems like a very good and useful utility. Proxo and other filtering proxies don't get in the way of that, they work well with or without ABP.

I doubt anyone uses Firefox exclusively, most will also use some other browser on occasion. ABP can't help its users with other browsers or filtering beyond a few simple blocking mechanisms.

I don't see where there's any conflict for discussion. People who use Firefox are wise to use ABP with a decent filter set. Them and also everyone else in the world would be wise to use a personal proxy with a decent filter set.
