I’ve mostly used AdBlock Plus previously but as a Firefox user I switched to AdBlock Ultimate at some point based on Mozillas recommedation, yet I can’t fail to notice that AdBlock Plus has most installs but comes with a warning
That makes a compelling argument, especially the 3rd point but the first two also apply to AdblockPlus, is there any dirt on them, is it the default acceptable ads “controversy” or some other reason why Mozilla doesn’t give them a trusted/recommended badge? They do this with a bunch of other blockers with a much smaller user base.
