5 Best OnlyFans Video Downloader Firefox Extensions in 2026

Watching content on OnlyFans is simple when you’re online. The problem starts when you want to save a video to watch later. Unlike many other platforms, OnlyFans doesn’t provide a built-in download button for most content. So if you want to keep a video on your device, the usual option is to use a browser extension.

If you use Mozilla Firefox, several add-ons can help with this. These small tools work inside your browser and detect videos on the page. Once the video is detected, you can download it with just a click. But not every extension works well. Some are slow, some stop working after updates, and others don’t support all videos. That’s why it helps to know which ones are actually reliable. In this article, we’ll look at five onlyfans video downloader firefox extensions that can download OnlyFans videos and see how each one performs.
