So so so frustrating that AdBlock comes with spam these days. Every day, Adblock opens a New Tab requesting that I pay to upgrade to "premium Adblock"...whatever that nonsense is. This behavior only began roughly 1-2 years ago, when Adblock started going downhill. The straw that broke the camel's back tho was that Adblock recently decided to hide the "Block something on this page" button—the only feature that I ever really valued. So, reader, do yourself a favor: skip Adblock & just stick with **uBlock Origin**... it's free, zero spam, & vastly better performance.

First thing that happens is that you are presented with a page that asks you for money. Where in this FF posting for this add on say that you must pay for it? Not interested, thanks. Bye

The ad blocker has intrusive pop-ups just like the things it's designed to protect you from now.
They disguise them as "update" notifications but they are pushing updates every week and if you have the extension on multiple devices it will take over whatever tab you have open and show you that it's updated for the 5th time this month on every single device and conveniently also have an option to donate money.
The annoyance quickly builds up. After being interrupted and having to close a good 20-30 pop ups across all my devices a month, I'm done.

It’s quite ironic that an ad blocker designed to eliminate unwanted commercial spam ends up opening its own unwanted commercial spam. I understand the need to monetize, but opening a new tab to push a subscription offer feels intrusive. Most people are already overwhelmed with numerous subscriptions and don’t want to add another. This approach undermines the very purpose of using an ad blocker in the first place.

Rethink your marketing efforts, AdBlock. Do better.
