Google Chrome Developer Tools Lighthouse Audit Tips

-

This post shows some of the tips that appear during the auditing process when generating a report using Lighthouse within Google Chrome Developer Tools.

I saw these tips flash up and they sounded quite interesting but they kept disappearing when the audit finished before I had a chance to read them.  I screen grabbed a few and thought I'd share them.

This post describes how to fix the error "This app will now restart to free up more memory" which can occur when using apps such as Netflix on an LG TV after just a few minutes of use. Resolution To resolve the issue, unplug the TV then press the on/off button for 10 seconds.  Wait a further 20 seconds then plug the TV back in and turn it back on. Apps should now run without the error. Edit: The on/off button on my LG TV is directly under the standby light on the bottom of the TV. Edit: I didn't have to do this myself but one person who has left a comment said that clearing all browsing data worked for them.  I have written a post explaining how to do this: LG TV Clear All Browsing History Data .
