Vimeo video not playing in Firefox
First of all, clear all Cookies, Internet Cache & History. You will be able to do this via Options > Privacy & Settings. Now start the Firefox browser in Safe mode. See if this helps. If this is unable to resolve the issues, then you need to go for advanced error fixing. Open your Firefox browser and type about:config in the address bar and then hit on Enter.
Now you have to click on ‘I accept the risk’ option.
In the next step, search for media.autoplay.enabled.
Check whether it is already set to True or not or else double-click on it to toggle the value. Now, right-click with your mouse and select Boolean under new option, then in preference name enter media.autoplay.enabled.nppl3260.dll.
Click OK then select False as value and press OK. Restart the browser. Now, get back to the video that you have been watching earlier. Now, you will be seeing all player controls and will be able to play the videos unlike before. These steps will definitely help to get out of the problem that you are facing on Firefox
