Powerful and easy to use. Some website have lots useless URL script kind of, that slow down the page loading. This addon can filter out those elements only by keywords and then those websites open lightening fast!

Absolutely essential.

This guy literally saved the whole Internet.

A must have

Firefox settings says "disabled by private viewing. Don't know how to correct this. Please help.

2-5-25: hasn't iimproved still slow to load. same as last review
8-31-24: degraded one start. TOO SLOW. Doesn't work with some pages. SLOW to load, slow to capture, just plain SLOW. Takes forever to delete segmented ads you wind up spending all your time blocking each segment. Have recently had to reinstall never had to do that before. No way to easily report pages that don't work.
7-29-24: cannot deal with pages such as gab.com that keep changing the address of the same add. You have to keep blocking it over and over again and editing the script does no good. Too slow to load sometimes cannot load it.Sometimes too hard to select the portion you want deleted. It's still good but not as good as it used to be.


10-20-23: getting slower to load or won't load or won't show gui to delete ads. can't capture some site's ads. no way to delete all the little social widgets at the same time. just getting TOO damn slow
3-17-23: Still the best addon on the net. But always room for improvement. Slow to respond often. Doesn't work on little social media widgets because you spend more time blocking each one than it's worth: fb,and others. No way to easily report pages where it does not work. Slow to mark offending jpgs and slow to load and block them. Still a very good addon, indispensable.
12-17-22: So far I see no way to block these little social media widgits which you have to delete one by one and this takes forever. Many sites incorporate their garbage into the main page and it's difficult if not impossible to get rid of it. In short it works like 95% of the time and for 5% you have to put up with website garbage. No easy way within the program to report sites and bugs.
7-20-22: no easy way to report pages that block it's use. Some pages it will not work. Often slow to bring up the block window.
9-16-21: Still great. On some sites when you try to use the eyedropper, the popup for the script to delete the ad does not appear or appears and then immediately disappears or does not appear at all. Making it difficult to select the script that needs to be blocked. Still a great addon though.

If you don't have ublock origin, you should get it. Best add on on the market. Extremely useful in eliminating the garbage idiot admined websites throw your way. Has a learning curve but not bad. Kudos to the developer for this program, wish they'd design a web browser too. Great.

Soon, we should come up with a petition to declare uBO as the best Firefox add on of all time.
