User Reviews

Pros: easy to use, quick Lighthouse analysis in Firefox desktop, and time-saving reporting features. Cons: lacks localhost testing, frequent test failures/load errors, and reliance on an external Lighthouse viewer (internet needed) which hampers local testing. Android support is limited and Chrome tends to perform better for Lighthouse. Overall, convenient for quick checks but unreliable for local development or offline testing.

Pros

Easy to use and simple experience
Provides Lighthouse analysis in Firefox desktop, saving time
Quick saving and printing of Lighthouse reports
Helps analyze the site and reduces dependence on PageSpeed Insights

Cons

No localhost/local development testing; can't scan local sites
Frequent test failures and page load/document errors
Relies on redirect to external Lighthouse viewer / requires internet; not suitable for local testing

Only lets you see stats for the mobile version of your website. I know Google prefers that, but it's not Google's website, it's mine, and it's not Google's users, they're mine, so it kind of makes this useless to have Google make a decision for me that I'm not interested in seeing desktop stats, when I actually am more interested in them than the mobile stats.

Is Google Lighthouse Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Google Lighthouse does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Google Lighthouse has earned a fairly good reputation and likely can be trusted.
