Really love this Add-on as it is easy to use and can block any script just by right clicking on your mouse button! If you wish to cancell the selection of the item to block, click anywhere on the page and move the mouse around to find which area gets highlighted in red to block.
If you make a mistake, simply go into the 'My Filters' tab in the settings and remove the most recent entry which will be number the highest being the newest addition to being blocked.
Best Addon in Firefox!

hi this is five star - but there is a new problem that allows ads to bypass ublock - websites add new js javascript urls during reloads - so if an ad is blocked, the next time you visit, or if there is a page reload, the ads return with a new javascript js url.

Love, love, love this app. Makes web browsing more efficient, without the excess annoying "junk" ads! Clean up your browsing with this app: It's a must have!

Intuitiva y a la vez muy configurable. Complemento indiscutible.

I dropped AdBlock Plus for uBlock Origin about 1.5 years ago and couldn't be happier with the decision. Blocks almost all ads, is easy to use, few issues with affecting site features, and no noticeable performance hit. I always recommend it to friends, family, and clients, telling them that if they only ever pick one add-on to install, pick this one.

Easy, quick and effective. Did not notice any speed loss in page loads

good theam
