Did you ever encounter issues like Mozilla Firefox not responding on your computer or mobile device? If yes, you can get rid of such issues by either waiting for a couple of minutes to see if the issue gets resolved on its own or clearing the browser cache files and cookies. To do this, you need to go to Firefox browser settings and select a time range to remove the cache files and cookies. In addition, you can try clearing the browsing history from the device and check if Firefox works fine. In case the issue persists, check if the browser is updated. If not, click on the ‘Update’ option located next to the Firefox icon on the browser and wait for the update to complete.
