Ranked in these QuestionsQuestion Ranking
Pro Syncs between devices
By logging into Chrome using a Google account it's possible to sync history, extensions, passwords, bookmarks and other settings between devices. This makes it great for anyone working with multiple devices as it allows experiencing consistent context when in the browser.
Pro Excellent HTML 5 feature support
As of February 2015, Chrome scores highest of all browsers for HTML5 compatibility.
Pro Installs extensions without requiring a restart
Pro Plenty of extensions
There are far more available on this browser than any other.
Pro Simple user interface
For example, the address bar is also the search bar. Google calls it Omnibox.
Pro Good performance
According to TopTen Reviews, Chrome is currently one of the best performing browsers for initial (cold) startup, average startup, and navigation times. Works very well with the uBlock Origin adblocker.
Pro Great built-in developer tools
Chrome comes with built-in developer tools, making testing and enhancing web pages simpler for those of us involved in working with such technologies. As well as being beneficial to developers, this also has some benefit to non-technical users; in that by making testing simpler for developers those developers are more likely to use Chrome for their tests, and can spend more time making improvements over investigating underlying causes of issues.
Pro Automatically updates
Chrome updates in the background ensuring you're always on the latest version. This makes it much more likely that sites will work on your browser, since (almost) all Chrome users will be running exactly the same version.
Pro Sandboxed Tabs
Every tab runs as their own process, so if one crashes or becomes unresponsive, the whole browser isn't affected.
Pro Huge variety of extensions available
Pro Multiple account login
You can have multiple Chromes with different accounts logged at the same time. And it is really easy to manage different accounts.
Pro Backed and supported by Google
Whilst Chrome is based on the open source browser Chromium, Google reviews this code and build on top of it. This means it takes (and contributes to) a number of the benefits of the open source model whilst having the resources, support and investment of a major company.
Pro Works great with many extensions
Unlike Firefox, Google Chrome can keep its fast performance regardless of how many extensions are installed. With more than 10 extensions Firefox gets slower and slower in a geometric progression rate. Google Chrome doesn't care how many extensions the user has installed - 3 or 133 it still performs great.
Pro Engine is open-source
Chromium is open source, except the proprietary media codecs like AAC, H.264, MP3 and Adobe Flash, that can't be legally open-sourced.
Pro Customizable by user
Each of the managed users can have their own configuration (themes, extensions, ...)
Pro Can translate text directly
As of March 2015, Chrome is the most popular browser on the internet, with a 43.9% - 63.7% market share, Its rendering engine Blink is also the most used rendering engine and used in many products including: Opera, Vivaldi, Qt, Brave, Steam or Electron meaning most developers will be testing their sites against this browser to ensure compatibility.
Pro Uses Blink
It uses the blink rendering engine which has removed many legacy khtml/webkit code to be much lighter and faster.
Pro Multimedia Plugins and Codecs included
Google Chrome comes with its own flashplayer and the most common multimedia codecs so you don't have to worry that they are outdated nor do you need to install them as a third party package.
Pro Only one distributor
Unlike those various unofficial Chromium builds, there is only one distributor, so all Chrome releases follow the same standards.
Pro Chrome is faster than Firefox
Pro Plays more media formats than any open source browser
Includes support for many licensed unfree media formats.
Pro Data Collection
Chrome uses online services to collect our data and improve our browser experience.
Chrome is Proprietary which means that it is easier to use and more user-friendly.
Pro Strong HTML5 feature support
Pro Free, open source and community driven
Firefox is available as a free download. All Mozilla software is licensed under the Mozilla Public License. Instructions on how to obtain the source code can be found here.
Pro Syncs between devices
Firefox Sync is an optional feature in Firefox that allows syncing bookmarks, passwords, and add-ons between devices.
Pro Strong developer tool
The built-in developer tools have been merged with the popular FireBug extension since FF57.
Pro High performance
The Firefox Quantum update (FF57) greatly increases the render speed and general performance of the browser, by taking better advantage of the user's hardware.
Pro Reader View
Reader View in Firefox allows users to read an article without any distractions by removing ads, unrelated elements and other distractive objects (similar to Microsoft Edge's Reading Mode and Safari's reader mode).
Pro Uses less resources
Firefox 57 (Quantum) and newer uses less resources than ever. It is proven with benchmark done by AppleInsider.
Pro Good font rasterizing
Font rasterizing on Windows is much better than in competitors. Even smaller text is clear and contrast.
Pro Tagging bookmarks
Firefox is one of the few browsers that you can tag your bookmarks. You can view a list of tags and can search your bookmarks in the address bar with tags.
Pro Awesome customizability
Great library of add-ons.
Pro Android version allows installation of addons
Unlike other browsers, Mozilla uses almost the same codebase as with the desktop version so extensions work as-is without code modifications - something other browsers cannot do due to their breaking and sometimes unrelated code branches to the mainline desktop branch.
Pro Automatically updated
Firefox is automatically updated on the platforms where it makes sense.
Pro Dark theme
Beyond the toolbar and tabs, it darkens UI elements such as the URL-bar, pop-downs, new-tab page and more.
Pro Respects your privacy
Mozilla is one of the first browsers that advocates privacy. They believe that internet should be in the user's control and not those who run the websites, and so they give tools inside the browser to make the user be more in control.
With new integrations focused on security and performance, Firefox is faster and less likely to have problems during use than ever before.
Pro Ethical and pragmatic company mission
The Mozilla Manifesto outlines the company's mission and principles. Paraphrasing, they want the Internet to be a free and open resource, and to enable individuals to get the best use of that resource. They do this by creating open source software to which anyone may contribute, so long as such contributions fit with their principles (both ethical and technical).
Pro Fast bookmark management
In order to add an open page to the bookmark bar, the tab can be dragged down and is added immediately.
Pro Screenshots tool
Powerful screenshots tool built right into the browser.
Pro Open Source
Open Source means that you can see the source code. So everybody even if they don't work for Mozilla is able to look what the browser does in the background. So you can be 100% sure that Firefox doesn't have hidden "spy features" unlike Google Chrome.
Pro Lower memory fingerprint than competitors
Firefox used to be a trailer in memory usage, but as of 2017 it's less hungry for memory than competitors like Edge, Chrome, Safari and Opera.
Pro One of the few browsers not using Chrome's Blink engine
Firefox uses its own rendering engine (called Gecko), instead of Google-controlled Blink like the vast majority of other browsers.
Pro Text-to-speech (with adjustable speed) without add-ons
Firefox Reader Mode includes Narrate, a feature that adds text-to-speech functionality to the browser.
Pro A lot of add-ons
An enormous number of add-ons.
Pro Really independent browser
It is really independent browser, unlike many other that are based on Chromium.
Pro Firefox Experiments
FF Experiments are Mozilla projects available from FF Test Pilot, such as Firefox Colour, witch lets you customise your browser theme to your liking!

Pro Integration with Pocket
Firefox comes with built-in Pocket integration that can allow users to quickly save the article for a read it later function to easily find any articles saved in Pocket from various sources and devices.
Pro HTML5 Video Preload
The only web browser that only preloads entire HTML5 video which is useful for slow internet.
The newer versions of it will soon use WebRender to render webpages, which'll make it much more efficient by utilizing GPU to paint webpages.
Con Online tracking by default
Chrome allows opting out of tracking by going to Settings > Advanced > Privacy and un-checking any unwanted services. Alternatively Chromium can be used to get a similar browser experience without Google's services on top of it.
Con Huge memory hog
Each tab and extension in the browser uses significant chunks of RAM, giving the browser poor performance on machines without enough RAM to supply.
Con Bad for battery life
Drains battery life on both Windows laptops and Macs much quicker than the alternatives. It can shave hours off the battery life of any non Chromebook laptop.
Con Not fully open-source
While most of Chrome is open source: Chrome does have some closed-source components to make it possible to play some closed media formats.
Con Increasingly slow
When Chrome first came out, it was known for being lightweight and very speedy. Over the years, more and more features have been added to Chrome. Because of this, crashes, errors, and general laggy-ness has increased noticeably.
Con No mobile extensions
Chrome on Android and iOS does not support extensions.
Con Not as customizable as Firefox or Vivaldi
Con Big target for hackers
Chrome is the most popular browser in the world. That makes it the most targeted browser in the world by hackers.
Con Blurred fonts on Windows
Fonts on Windows are blurred, that is especially noticeable in light fonts on dark background. Small italic text is hard to read.
Con Hard/impossible to transfer passwords to a different machine without uploading them to Google
Con Does not hardware accelerate HTML5 video correctly
Chrome is unable to hardware accelerate HTML5 video correctly which makes playing 4k video on laptops a poor experience filled with lag.
Though there is a workaround for YouTube in that a plugin can be installed to force Flash playback instead of HTML5, which plays smoothly and has no HW acceleration issues. There's another plugin (h264ify) that will force to use the h.264 codec video if available instead of the VP9 one which is the resource hog.
Unlike Opera and Vivaldi which are more stable and has more features, Chrome is pretty basic.
Con Bad quality control on extensions
Some just plain don't work while a few actually break the browser.
Con No menu bar (except on Mac)
There's no no menu bar, except on Mac OS.
Con No reader view
Unlike most other browsers, Chrome doesn't have a reader view function.
Con Gives too much weight to Google on the future of the Web
Con Some built-in advertising
With their new "pocket" feature, they offer advertisements built-in.
Con GTK Themes styles the HTML forms
If you're in Linux and you use a dark GTK theme that uses white text and come to a webpage that forces black text on html-forms buttons you will get black buttons with unreadable black text.
Con Pocket integration
Con When you search in a website (Ctrl + F) there are no marks appearing in the right scrollbar
All Chromium based browsers have this feature.
Con Installs Addons with updates
Mozilla is installing/integrating addons with every update like the Mr. Robot promotion - it also has integrated Pocket that spams you every time you open the browser or a new tab with partners of Pocket.
Con Lack of keyboard shortcuts customization
Keyboard shortcuts can not be changed in a user-friendly way.
It is also difficult to manipulate addons with hotkeys.
Con Uses GTK on Linux/BSD
This makes the integration on non-GTK Desktop Environments very hard.
Con Cannot directly translate page
Unlike Google Chrome, if you visit a website with a different language, you cannot translate it, which is a bad user experience for some.
Con Sometimes very buggy and slow
On sites like twitch.tv chat scrolling is still not fixed. Compared to other browsers Firefox is still very slow and feels sluggish.
Con Crappy license
Cannot redistribute binary after source code modification.
Con Devtools for WebExtensions are buggy
Con Multi Profile are not user friendly
Multi profile require commandline -no remote to use and open about:profiles to create manually (on Chrome, you can instantly create them on right top user button).
Con Uses Google as its default search engine
Which is pretty ironic for a browser that's focused on "privacy".
Con Abandoned XUL for webextensions
Con Terrible user interface
And you can't even fix it anymore because they removed XUL
Con Supporting Gecko makes no sense
Since Blink is available under a more open and permissive license.
Con Partial dark mode
Bookmark, context menu, etc. are not themed.
Con Cannot open multiple instances
You cannot open multiple Firefox windows at the same time.
Con Doesn’t support multiple languages for spell check
If you write in multiple languages, you need to manually switch the spell check language.
Con Uses extremely old browser version
Firefox uses a 15-year old version of Netscape, which has been dead for years
Con Doesn't care for its original guidelines/goals
Mozilla originally aimed to be the "good guys" with user choice and privacy in mind. Their current leadership cannot be trusted to hold those goals in high regard:
1) Added Pocket - a privacy data sensitive plugin, made it mandatory
2) Tried to sneak in advertisement as "drive-by hack", backpedaled unconvincingly once users complained
3) Tried to randomly inject a small percentage of Firefox downloads in Germany with a data collecting plugin (Cliqz) that tech-savy Germans consider adware (no opt-out question asked).
Con It's a memory hog even though Mozilla claims it is not
Mozilla claims it's using 30% less RAM than Chrome but in real life tests it uses much more.
