Very good addin but it's becoming very heavy keeping the CPU at 100% for long time before the page is completely loaded. Very bothersome!

In Firefox Profiler Adguard sucks 66% of the entire Extensions resources for very single loaded page although the Browser has been set to use GPU Graph as much as possible.
