Comment summary: Mozilla Firefox is praised for its extensive add-ons, high customizability, and privacy features, with many users appreciating its open-source nature. Though regarded as slower than Chrome, especially on older systems, it remains popular for its user-centric approach and security. However, criticisms include performance issues on some hardware and recent feature decisions by Mozilla. Overall, Firefox is a favored choice for those prioritizing privacy and customization.

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/

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.

Firefox isn't a perfect browser for privacy by default, but it can be hardened to be more private than even Brave. https://www.privacyguides.org/en/desktop-browsers/#firefox

The Mozilla foundation has unfortunately seen better days, and I can only hope it recovers in the future...

I've been a Firefox user for 20 years now. I've tried other browsers, including its forks... but I've always come back to Firefox: secure, customizable, and with a reputation that's been consolidated over the years... a guarantee of continuity in short! I also use it on Android as an alternative to all the native apps (Gmail, YouTube, etc.), and my smartphone breathes better!

Mozilla Firefox

This is my overall favorite browser, regardless of the operating system I'm using, whether it's Windows or a Linux-based system. I know many websites are trying hard to make it obsolete, but I refuse to give it up for as long as possible.

My Favorite Things About This Program:

★ 100% Free ★ Easy to Use ★ Many Great Add-ons ★ Account Sync Across Devices ★ A Variety of Great Features

Some of My Favorite Add-ons:

★ 600% Sound Volume (PC/Android) ★ AdBlocker Ultimate (PC/Android) ★ Amazon Ad Blocker (PC) ★ DuckDuckGo Privacy Essentials (PC) ★ Popup Blocker Ultimate (PC/Android) ★ YouTube NonStop (PC) ★ Adblock Plus (Android) ★ uBlock Origin (Android) ★ uBlock Plus Plus (Android)

Things I Wish Were Added:

★ ???

Honestly, I am happy with Firefox as it is. As long as it stays alive and well, I’m completely satisfied with it!

It's open source, it's been around since 2004. It's Chrome's main competitor, and it has a loyal base of users. Its extensive features make it the best alterative to Google Chrome. It has better privacy options, its many customizable and useful add-ons (ad-blockers or dark reader mode are gold) are great to help you navigate the internet how you want. It uses less memory and loads faster than some others browsers (in my case). I have used it in the past, but I quit because of Chrome's new direction. But lately I had to return to Firefox because I've read of how much improvement of late it became. The Mobile version is also a good alternative to Chrome or other browsers. Even on smartphone/mobile, you can enjoy surfing the internet like on a PC. And I can confirm that by utilising it with pleasure.
