Usually good till youtube messes with things. The last while, it may have started causing massive memory leaks with youtube. Just like it youtube does with other popular adblockers. Even turning off the adblock function of this addon, there might still be memory leaks. I could be wrong though. Might be worth looking into? Maybe let us turn off storing client-side data?
Thanks for the feedback, we have a major update for Firefox coming soon. Unfortunately client side data is needed to store the databases that protect you.
