When comparing Mozilla Firefox vs Google Chrome, the Slant community recommends Mozilla Firefox for most people. In the question“What are the best desktop web browsers?” Mozilla Firefox is ranked 2nd while Google Chrome is ranked 5th. The most important reason people chose Mozilla Firefox is:
Firefox [scores strongly on HTML5 feature support](http://html5test.com/results/desktop.html).
Ranked in these QuestionsQuestion Ranking
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 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 Automatically updated
Firefox is automatically updated on the platforms where it makes sense.
Pro Awesome customizability
Pro Good font rasterizing
Font rasterizing on Windows is much better than in competitors. Even smaller text is clear and contrast.
Pro Uses less resources
Firefox 57 (Quantum) and newer uses less resources than ever. It is proven with benchmark done by AppleInsider.
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 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 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 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 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 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 Easy screenshots without extensions
Within the browser itself, you can easily take screenshots and save them to your computer.
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 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 Screenshots tool
Powerful screenshots tool built right into the browser.
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 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 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 Plenty of extensions
There are far more available on this browser than any other, and that may matter for some.
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 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 Simple user interface
For example, the address bar is also the search bar. Google calls it Omnibox.
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 Customizable by user
Each of the managed users can have their own configuration (themes, extensions, ...)
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.
As of March 2015, Chrome is the most popular browser on the internet, with a 43.9% - 63.7% market share, meaning most developers will be testing their sites against this browser to ensure compatibility.
Pro Sandboxed Tabs
Every tab runs as their own process, so if one crashes or becomes unresponsive, the whole browser isn't affected.
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.
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 Uses GTK on Linux/BSD
This makes the integration on non-GTK Desktop Environments very hard.
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 It's a memory hog even though Mozilla they claim it is not
Mozilla claims it's using 30% less RAM than chrome but in real life tests it uses much more.
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 Poor performance on SSD even without extensions
On a fast SSD such as Corsair Force LE series this browser still performs as if it were installed on a regular hard drive disk, meaning it takes long time to start, even without any extensions. On that matter Google Chrome is light years ahead of Firefox. This applies only for Firefox versions below 60!
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: https://www.cnet.com/news/mozilla-backpedals-after-mr-robot-firefox-misstep/
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) : https://bugzilla.mozilla.org/show_bug.cgi?id=1406647
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 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 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 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.
Google Chrome is proprietary software, meaning that it is not open source.
Con Hard/impossible to transfer passwords to a different machine without uploading them to Google
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 No mobile extensions
Chrome on Android and iOS does not support extensions.
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.
