    Version updated to 1.71. Interestingly, with SuperAdblock Test, uBlock scored lower than MV3 Aguard. And unlike Adguard, uBlock (this version) doesn't block cookie annoyance banners from the CBC News site despite adding it the filter list. And as of March 12 this extension is still supported on Chrome. I don't understand all the whining. Everyone should be grateful developers are still maintaining it instead of yanking it.

    This is the best extension on the Chrome Store. It's so good that Google had to allegedly get creative and change the Material Design format to make uBlock Origin not work anymore as designed, forcing them to create a stripped down version as a replacement.
