Excellent browser and love all it's features; yes I have used others; Vivaldi, Safari, Chrome, Opera; all have something to offer, but Firefox hit me with a brick, after I learned how to sync my account, so I will lose nothing. The 'Generic forks; Cliqz, Waterfox, Pale Moon and others do not present the needed security updates and new versions as quick as Firefox. Firefox is at 73.01, and is rock solid. I do not have a cell phone, so my data is synced with Firefox. I read the complaints by choice, reviews; that will not stand in my way. If you are not a fan of FF, please use another browser that floats your boat; that is using a "moral compass"

HEADS UP, a 77.0.1 update was released in less than 24 hours after 77.0.0 was released, fixing a fairly important bug that shipped in 77.0. MU will probably take awhile to even register the 77.0.1, so if this page is still showing 77.0, you may want to go direct to Mozilla and download the .0.1 update.

Little bit of a re-learning curve. But after a couple months I love it. Sayonara Safari.

I don't like it. No option for custom keyboard shortcuts and it uses 10x more CPU than other browsers (Safari, Brave, Chromium).

Firefox is a browser I use on macOS Catalina, iOS 13, and Windows 10. It's been incredibly useful for the past several years, but the recently introduced privacy controls have made it exceptional. Using Sync to keep my bookmarks, passwords, and site preferences across devices is amazing. Having Lockwise on iPhone allows me to get at those to feed my information to apps carefully. The one downfall I've recently seen is that 4 GB of RAM on Catalina means that Firefox won't work correctly. Still, I'm using a mid-2012 MacBook Pro and now, with 16 GB, Firefox seems as good and quick as it did when this machine was new. It doesn't seem to work quite as well on Hulu as it should but that's because of the privacy controls not allowing some advertisers to stream their bits. I can use Safari for that because it doesn't seem to have much in the way of privacy controls.

The Browser Is quite fast and I am also happy about the Savenet site, which I presume is safe.

Firefox as a general browser works wonders for me on a really old 2011 machine. Safe, fast and compatible. The only letdown I feel is older add-ons have lost support. That's a good thing though as Firefox evolving means better security and it's the add-on developers that need to update their software when Firefox changes. I feel verifiably safer using FF and every media site I use Soundcloud, Spotify, Netflix, HBO, youtube, vimeo and so on works fine as do all sites. If one doesn't, I add my own controls with add-ons to adjust things like presentation or scripts.

Firefox is, sadly, dying a slow death, steadily losing market share (since at least 2015) mostly to "Chrome," and no doubt taking parent company Mozilla down with it. Mozilla, to avoid operating in the red, and top-heavy with clueless management, is shedding developers and is still looking for a permanent CEO. The 'Pocket' acquisition, which somehow Mozilla execs (who are largely impervious to input from actual users) thought would GENERATE revenue, is no doubt an abysmal and money-sucking failure, and is emblematic of their inability to position FF in the market. Experienced, tech-savvy FF users don't need Pocket -- it's a glorified bookmark recorder -- and no one using a different browser is going to switch to FF to use it. (BTW, you can shut down Pocket from about:config, by setting extensions.pocket.enabled to FALSE.) And while on that subject, why does FF still have hundreds, if not thousands, of obtuse preferences (that DON'T SYNC) still accessible only via the barely documented about:config? (see: (http://kb.mozillazine.org/About:config_entries#Advanced.) So very strange. And please, no more smug comments that people like me -- longtime FF users -- should use a different browser. Firefox, for all its faults, is still the BEST and SAFEST BROWSER available. Mozilla should be HAPPY that we haven't jumped ship, even as it makes FF more difficult use. It's a shame, though, that the company still really doen't "get it and simply doesn't care about customer imput -- including comments like these. Too bad. Bottom line: Enjoy Firefox while you can, people, because its days are numbered. -SB
