I just uninstalled Adblock Plus to try out this add-on. I installed the add-on and restarted my browser. After restarting, it was a little faster with this add-on. My problem is that when I went to a site, example: www.videoweed.es, the add-on didn't block all of the adds. There wasn't any button in the browser to "report" the unblocked adds. When right clicked, nothing either. Its like the extension is blocking some, but not all of the ads. Also, I visited the Firefox home page to write a review on this add-on when it was enabled, I could not scroll down to see what I was writing. I had to disable this addon, to write a review on Firefox's review page. I'm using Firefox's Aurora browser on Windows Vista platform. It updates itself every two days. The current version is 11.02a. This add-on may be faster than Adblock Plus, but it has flaws that needs to be fixed. Thinking about switching back.
