No me funciona siempre muestra "No se ha encontrado esta página web"
Getting the same behavior described by Manan Patel The installed icon is decorated with the word "beta" white on green background. Are you kidding me? Does Google really publish "BETA" extensions? Anyway when the icon is clicked the message is: This webpage is not found ERR_FILE_NOT_FOUND With a link labeled "DETAILS". When DETAILS link is clicked the following message comes up: No webpage was found for the web address: chrome-extension://lanlbpjbalfkflkhegagflkgcfklnbnh/guide.html
It is not working. Every time I am getting this error message: "This webpage is not found ERR_FILE_NOT_FOUND"
не работает. как и у предыдущих Не найдена страница для веб-адреса chrome-extension://lanlbpjbalfkflkhegagflkgcfklnbnh/guide.html Код ошибки: ERR_FILE_NOT_FOUND App doesn't works. Error described upper. Please fix it.
Works great, not sure why people are saying it doesn't. You need to make sure you're looking in chrome dev tools (hit F12) and you will get a new tab button 'Page Speed'. Within page speed, you can analyse a page which will return an overall score with many recommendations, ranked in order of severity.
Not working waste of time.
