Firefox is now offering a solution: All audio and video content can be blocked automatically in the latest version of the browser.
If there are videos or sounds you want to have play, you can simply click on the play buttons, or create an exceptions list for websites that you want to authorise for playing content.
Chrome, meanwhile, doesn't offer a native feature for blocking autoplaying videos on websites, but the browser does tell you which tab is making noise – just look for the speaker icon at the top of the tab.
Another new feature on the latest Firefox update is scroll anchoring, which makes it easier to read longer articles without content jumping around as ads reload at the top. Firefox 66.0 is available for download now. – dpa
