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 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 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 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 Available on several distributions
Midori is used as a default choice for a web browser for some distributions (like Elementary OS) and it's available for easy downloading for many other distros through their official repositories.
Pro Very fast
Midori is considerably fast. It starts up in no time and renders pages as fast as many other more well-known browsers.
Incredibly lightweight with very little memory consumption.
Pro Allows using webapps as if they were desktop apps
Midori has a built-in functionality with which you can create web apps that can be launched from the desktop. For example, you can create a web app for the desktop to launch Gmail or YouTube or any other web app that you use.
Pro Useful plugins are built-in
Some very popular and useful plugins are built-in and available out of the box. For example, there's an RSS feed reader plugin and an Adblocker built-in.
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 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 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 Uses GTK on Linux/BSD
This makes the integration on non-GTK Desktop Environments very hard.
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 No status bar
There's no status bar. Granted, there is a status tool-tip. But what if you want an actual toolbar, you're out of luck.
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 Misbehaves with Google Web Apps
On some distributions Midori may not work very well for Google Web Apps. On openSUSE for example, Midori starts misbehaving when you are going through Google Drive's folder hierarchy.
Con Another bloatware as firefox
It is described as a lightweight browser but it is just a bloatware. It crashes sometimes. It is a clone of firefox which is said to be a RAM-eater.
Con Development stalled
There have been no recent updates. Lags other browsers in supporting modern web standards. Many distributions have replaced it with other browsers
Con Supports insecure cipher suites
This browser supports RC4 encryption which is known to be insecure compared to other encryptions such as AES.
Con Unfamiliar UI
The UI can take a little to getting used to because it's not very conventional or similar to other browsers. For example, it uses a trashcan icon to view recently visited links.
