Used to work great, but with the 2023 new year, about half of the websites I need to log in to I can't until I disable ublock. Have tried fresh installs and removing some default filters that are included and still no success. The final straw was being unable to disable the ublock popup blocker. The button activates and deactivates, but it still blocks popups. Again, disabling ublock fixes it. At this point, I have to recommend against using ublock until they come out with some updates.

Best blocker out there, thanks for your work!!

Edit: Checked out AdNauseam, a fork of uBlock that quietly clicks every ad in the background. This way randomizes your browser fingerprint, while still blocking ads from being displayed.

I now recommend AdNauseam, but it's built on uBlock so the original review still stands B)

The most honest, trusted and useful addon of Firfox. I don't know why but Mozilla does deliberately try to make this addon a tad difficult to locate for the relatively less informed. Perhaps because it is too effective.

Gut

There is an evil twin of uBlock Origin. A fork. It's called AdNauseam. AdNauseam doesn't block the ads, it welcomes them in, invites them in a special place underground where it is dark and no one can hear them scream; it molests them and clicks on them. And every time an ad is molested like this, a content creator is happy because they are getting payed. At the same time, your digital footprint gets larger and larger ‒ because AdNauseam clicks on every ad in site ‒ and, through the data obfuscation, you become harder and harder to be digitally profiled. I wouldn't have write all this but I'm just amazed how insanely underrated AdNauseam is. I mean, really? AdNauseam only has 40k users? After all these years? How? Come on! If you want to give Google the finger and help content creators, you have to at least give AdNauseam a chance.
