Show Video Controls for Firefox is a free multimedia extension designed to enhance the user experience while watching webm videos. This tool automatically enables player controls for webm content, eliminating the need for users to manually activate them each time they navigate to a video. This feature is particularly beneficial for users frequenting meme sites like 9gag, where quick access to video controls can enhance browsing efficiency.

However, it's important to note that this extension may not function on websites that utilize custom video players, such as Instagram. As an unofficial version for Firefox, it offers a straightforward solution for users seeking enhanced video playback options without the hassle of additional clicks.
