I consider this a mandatory add-on for any Firefox installation, it makes websites tolerable and snappier.

If you use Firefox and don't use uBlock, you're doing it wrong. The ability to permanently remove webpage elements is still something I've never seen done as in-depth as this.

Simply great, but some websites don't allow it.

The internet is unusable without this.

Absolutely amazing.

Don't get fooled by the simple look of this add-on. This is the best ad blocker I have used in my life.
