This extension is for those who don't like to listen to five-minute audios every time, so next to the profile photo a 2x button will appear, and even better, you won't have to worry about changing the speed all the time, the state will be saved after your first choice!
The extension is already available in the official site to Mozilla and Microsoft Edge (based on Chromium), you can download anytime!
Unfortunately the extension isn't available in the official site in Google Chrome, even so you can use! You will need to clone or download the project and drag the folder to chrome://extensions, remember to active developer mode in the right side header menu.
