Below was a 1 star review for an old and very disappointing version of Adblock Plus. The 2019 and 2020 versions on Win10 are much better, but they're still not as user-friendly as the 2015 and before versions on XP. ABP wants users to allow acceptable ads, but those acceptable ads are items of their choice that you can't override without turning off the allow acceptable ads option. I might be prepared to accept 99% of items but not being able to block the 1% that are a nuisance. Not all the items I want to block are even ads. I choose to block the footer on the Google homepage because on enlarged settings it blocks the search functions. I can't block that item whilst allowing acceptable ads. Not smart.

Not just bad - it's HORRENDOUSLY bad! It takes 20+ seconds to switch on or off - which freezes your Firefox page. When you click on an element to block you don't know exactly what you're blocking. If you block an incorrect object, eg an overlay on a streaming site and you block the stream itself rather than the overlay, (a 50-50 chance), then God help you. It's nigh-on impossible to delete or edit the new custom filter.

A fantastic product that i've used for 10 years, (with over 400 personal custom filters) has been turned into a God-awful disaster that I will probably end up having to remove. What's been done to this product is akin to sabotage.
