I've been using this extension for many years and it doesn't disappoint - never.
Sometimes I go to a website and UbO stops me before it loads because to proceed would be dangerous.
KUDOS to Raymond Hill!

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.
