Firefox has some tools to track add-on performance, but they're not nearly as user-friendly. Plus, Chrome's task manager (access it by pressing Shift-Esc) breaks down how much RAM and CPU power each add-ons is using, so you can identify ones that may be causing issues with browser performance or device battery life. That matters if you're logging in and out of LastPass all day. For example, the login UI for LastPass is much nicer looking in Chrome than it is in Firefox. Two, the Chrome version of an add-on frequently has more work put into the user interface. So if you download a new version of Chrome or install an add-on on one of your devices, when you log in to your Google account in Chrome on another device, the browser will automatically download and install those add-ons or updates. One, your add-ons are linked to your Google account. The best add-on support: Chrome slightly edges out Firefox in two ways. Google's Chrome Web browser has become one of the most popular in the world, thanks to smooth performance, support for add-ons, and features like casting and voice search that are absent in or only partially implemented by competing browsers like Safari, Mozilla Firefox, and Microsoft Edge.
