It's the best browser and moved out from Chrome for security reasons. Chrome is having lot of Adware and collecting too much of data leaving behind without any option to disable.

I am still using 61.0 because that is when the comments section in the bookmarks was removed. Does anybody know if it has been added back in yet? As much as I would love to upgrade, I find myself using Chrome a lot more, so I can keep my comments section in Firefox.

Some nice additions/improvements for FF 69: For our users on macOS, battery life and download UI are both improved: macOS users on dual-graphics-card machines (like MacBook Pro) will switch back to the low-power GPU more aggressively, saving battery life. Finder on macOS now displays download progress for files being downloaded. Enhanced Tracking Protection (ETP) rolls out stronger privacy protections: The default standard setting for this feature now blocks third-party tracking cookies and cryptominers. The optional strict setting blocks fingerprinters as well as the items blocked in the standard setting. The Block Autoplay feature is enhanced to give users the option to block any video that automatically starts playing, not just those that automatically play with sound. For our users in the US or using the en-US browser, we are shipping a new “New Tab” page experience that connects you to the best of Pocket’s content. Support for receiving multiple video codecs with this release makes it easier for WebRTC conferencing services to mix video from different clients.

It is still a good browser, trying to adapt to new times. I don't know about the Windows version, but the Mac version is still slow. Consumes a lot of resources (especially when playing video). Rather, it is no longer an interesting alternative to Chrome or Safari, even though Firefox is still trying to modernize. The only plus may be that it does not belong to Apple or Google - for many people it matters.

Utter rubbish, badbadger. If FF is not running faster than Safari or Chrome on your Mac, you have something wrong on your machine. FF is customizable with many, many more extensions than Chrome, let alone Safari.

@badbadger is actually right, @Scion777. Safari uses less resources to play back HTML5 video, in my tests about half. However, this seems to come at a price. This Linus tech Tips video: https://www.youtube.com/watch?v=Po5iEqDDv3U will only show in 1080p in Safari 12.1.2 while Firefox 69.0.1 allows up to 2160p resolution.

FF is as slow as molasses for me; almost unusable. While I've followed all of Mozilla's instructions to clean it up, refresh it, etc, it's still a no go. I was forced to switch browsers and am now using the Chrome-based Vivaldi. The difference in speed is astounding – night and day. I've been with FF since the beginning, but the sloth-like performance is now a deal-breaker.

The same with 68.0.2 just released. To tell the truth, Firefox has always been a memory hog. It's only getting worse.

Today, MacUpdate offers for download Firefox 69.0. Strangely enough, at https://www.mozilla.org/en-US/firefox/ the download is still Firefox 68.0.2, How come? Can I trust the 69.0 version when the developer still doesn't offer it?

Chrome and Firefox let users data leak thru their extensions. https://arstechnica.com/information-technology/2019/07/dataspii-inside-the-debacle-that-dished-private-data-from-apple-tesla-blue-origin-and-4m-people/? This is one more reason to stop using both browsers.

Safari is number one. No complaints.
Brave is fine, but don't really use it. Years ago liked to use Opera, but it was before I switched over to Mac back in 2008. I'm curious about Microsoft new browser. More and more reports how Windows is on par with Mac. A lot of sites with detailed comparisons. Looks like new Windows is going to make many Mac users move to Windows.
