The motto of Pale Moon is "Your browser, Your way". But apparently not very so... The current ad system is broken and, although I understand Google decision to protect its own profits, I don't see why an open source project that aims to provide an unbiased browsing experience would follow suit.
How is "modify about:config" not having it "your way"?
With Firefox it started with a few small changes but in the end I have found myself working on an userPrefs.js with hunders of lines, compiling the source with custom build flags and patches just to have a browser that doesn't spy actively on me.
I really hope it won't happen with PaleMoon too but this isn't a good sign.
