Comments and Reviews

   
Comment summary: Firefox earns strong praise for its open-source foundation, privacy controls, cross-platform support, reliability, and unusually powerful customization and add-on ecosystem. Quantum-era releases improved speed and resource use, though experiences vary. Recurring criticisms include memory or CPU consumption, occasional freezes, compatibility problems, interface changes, discontinued legacy extensions, and weaker mobile performance. Some users still prefer Chrome or other Chromium browsers for speed and site compatibility.

Good privacy, many add-ons, open source, no Google

A great browser that's lost it's way.

As of 8/6/17 Firefox has begun to collect user data in an attempt to collaborate with Online News Association (A VERY partisan organization,) in an attempt to collect data on "fake news" websites and prevent users from seeing them. There are also rumors that they have teamed up with Piere Omidyar and are providing the information to help with his "fake news" censoring agenda. Mozilla, however, has yet to comment on the supposed relationship as of 10/9/17.

totally agree, I've had to use a modified version for over a year now. They have confirmed your statements with the actions described here: https://thenationalpulse.com/breaking/mozilla-threatens-to-go-beyond-deplatforming-in-creepy-statement/

cool

headlines

The only relationship between Mozilla and the Online News Association (a nonpartisan group of journalists) is when Mozilla collaborated on A-Frame, an open source VR framework that journalists can use in to present their stories stories: https://blog.mozilla.org/en/mozilla/mozilla-empowers-journalists-power-frame/ . It's ironic that you are complaining about Firefox blocking "fake news" when your entire comment is essentially "fake news" and I am reading your comment on Firefox right now.

Fishy, slow, not trustworthy

The normal Firefox is out of control. I use Firefox Dev as it uses a sensible amount of memory, about 600mb. The normal Firefox escalates upto 1200mb and my laptop is not happy. It's a shame as I was a big fan of Firefox.

Solid browser, does not feel that modern, though

It's fast, it's free, and it's been with me since the 1990's.

It’s a great web browser. Private and non chromium. However it is not private out of the box & many sites have better compatibility with chromium browsers. Though both of these things can be improved manually. still a decent browser for everyday use.

What is Mozilla Firefox?

Mozilla Firefox is an open-source web browser developed by the Mozilla Foundation. It uses the Gecko rendering engine for desktop versions and the WebKit layout engine for iOS. Firefox offers features such as tabbed browsing, spell checking, smart bookmarks, a download manager, private browsing, and a screenshot tool. It also provides web development tools, location-aware browsing, and an integrated search system.

Firefox supports add-ons coded with HTML, CSS, JavaScript, and the WebExtensions API. It also includes productivity, privacy, and personalization features like a URL autosuggest, reader mode, third-party cookie blocking, a built-in password manager, and customization options. It works seamlessly with Google products and offers a "Facebook Container" extension to prevent tracking by Facebook and Instagram. Users can sync their devices for cross-device access to tabs, history, and bookmarks. Other features include Enhanced Tracking Protection and a Picture-in-Picture mode.
