Firefox Quantum has narrowed the gap, but Chrome remains better for video above 1080p and faster than 30 frames per second, unless your PC has recent internal components that can take the load off your central processor -- a system called hardware acceleration. If you have that, then Firefox and Chrome are pretty even in our real-world usage testing. Google cloud services are tightly integrated: The browser itself has a Google account log-in dialog. When you log in, not only can you sync your bookmarks, browsing history and settings from other devices that you run this browser on, but you'll also get logged into Docs, Maps, Gmail, and other Google services.
At the same time, you can opt not to sign in to Chrome and just log in to those services on their respective websites. You can sync with Firefox and Safari, but doing so doesn't connect you to anything that resembles Google's cornucopia of cloud services. Cons Privacy settings could be enhanced: While Google constantly works on Chrome's security, its privacy settings could use better organization. Take Firefox's permissions settings, for example.
These are located right off the intuitively labeled 'Privacy & Security' section of the settings tab. You can isolate specific websites that are asking for webcam and microphone access, location data, and the ability to send you in-browser notifications. In each of these four categories, you can delete specific sites, delete all sites in one click, and toggle 'Block' or 'Allow' for each site. Firefox's system is straightforward. In Chrome's settings, you must scroll down to the bottom, click on 'Advanced,' scroll down to the ambiguously labeled 'Content Settings,' click on that, then click on the permissions category that you want to adjust. While Firefox has a prominent Settings button next to each permission category to help guide the user, Chrome's breadcrumb is a tiny arrow.
