Stop/Block/Remove Flash In Firefox With FlashBlock Plugin

Are you annoyed with Flash animations everywhere on the internet? Personally I find them very annoying on certain websites where it takes a lot of time to load. If you are using Firefox, then there is a little add-on for it called FlashBlock which removes all kind of flash animations and prevents them from loading again.

It also blocks Flash advertisements, which is very helpful when there are tons of them on a single web page. It works by blocking the flash content and then leaving a placeholder on the webpage that allow you to download and then view the flash content. In this way you can view the useful content and ignore other contents(such as advertisements).

It only blocks flash of three types, Macromedia Flash, Macromedia Shockwave, and Macromedia Authorware. If you don’t want to block flash contents on certain websites, you can add those websites to the whitelist.

Personally I am very annoyed by the ads next to videos, so I tested FlashBlock on a YouTube video page. This is how a video page looks like after you install the add-on.

You will notice that both the video and the advertisement has been blocked. Since I want to view the video only. I clicked on the flash placeholder(Play button) to view the content.

Notice that the video is now loading while the advertisement is still blocked. If you want to disable FlashBlock from YouTube or any other website, you can add them to the whitelist. To do this, go to Tools > Add-Ons and select FlashBlock from the list, now click Options and add the websites under WhiteList as shown in the screenshot below, and click OK.

Overall it is an excellent plugin, something that I should have installed a long time back. Let me know if you have any questions. Enjoy!

    What's missing is a blacklist, a list of websites where all flash elements are removed automatically.
