TBH, I don't see it live up to the marketing hype. There's also a bunch of other stuff that's kinda buggy: - Moving a browser window from a retina display to a non-retina external monitor causes the entire page to re-render in 2 seconds. When you move Chrome windows, you don't even notice the re-render. - Font rendering is a little strange. Most fonts appear thicker in Firefox. - SVGs also seem to have a slight difference, Chrome seems to render them better - The addon market seems very limited? Am I missing something or did Firefox have a pretty large marketplace before this? This isn't to say that it's a major improvement over old versions of Firefox. I just think the marketing hype may be a little misleading.

Is there an "Open in Firefox" plugin for Chrome?

Better than Chrome, but still not enough for me to switch from Safari! Quantum wakes my MBP's fans because it uses higher CPU usage. Safari does take more memory but it still runs pretty coolly with 20 tabs!

I would really love to switch from chrome and try it but I can't really stand their developer console :(

Biggest reason to use Chrome is not only speed. It is also about user experience. Days when You have to keep changing the browsers for different things have gone. It doesn’t matter if I change my devices or get new. One single google sign in get my all data there. Even though I believe every product has its market. Firefox will also but they are too late for the competition.

Have been using it for some time now and migrated everything from Chrome. The Firefox Quantum features a great speed improvement, indeed, and a sleek new UI. (Look at the update below). However, I don't really like that the address and the search bar aren't taking the whole empty space but are rather constricted in the center of the toolbar. This creates some awkward blank space around them and on the right side, it feels like there are several missing toolbar icons. Everything else I've seen about the UI feels great, especially the tabs, the colors and how unobtrusive the new UI is in the browsing experience.

Update: As others have pointed out in the comments, the whitespace around the toobar could be removed and the toolbar icons can be customized so this is not an issue.

It might be me, but I have also observed some issues with pages rendering (the Firefox install I'm currently running is clean from ad-blockers and such plugins). For example, when I open a startup page on BetaList, the main image is never loaded. It might also be a compatibility issue of this particular websites.

I especially like the sync feature and the ability to easily make page (or element) screenshots directly within the browser and without looking for thrid-party extensions.

Pros:

Speed; UI; Sync; Ability to do page screenshots;

Cons:

Found several websites which work great on Chrome but have issues with Firefox;

I moved to chrome about an year ago as Firefox was not only slowing down my PC but also productivity. I just used Firefox Quantum and I can tell this is way powerful browser than Chrome and I preparing to switch back just finding my Chrome extensions in Firefox now! P.s. It's Drone fired on Chrome not shots at Google Chrome!

I'm ok to wait my browser if in the end page will look good. https://imgur.com/a/Salge

My experience so far - I don't get all the hoopla over security vs Google - you are still opting to give your info to them + SalesForce + data on places you log into. It isn't like really secure, it is just shifting your data to a new company. It is faster on pre-load but many sites then lag, so you get to the line faster, but are likely still waiting. It seems to be using a lot of memory w only PH open and got my macbook fan going w 80+% of the CPU. 1 site open. This one.

This release is a stepstone. :)

Pros:

Efficient

Cons:

Impossible to drag an image from browser to desktop

Am I misinterpreting the video, or does it just show that firefox and chrome are about the same speed with some negligible differences on occasion... Thats fine, if so. Just seems like a weird way to market something.

have replaced all chrome usage with firefox developer edition!

Pros:

Fast and low footprint

Cons:

Extension support < Chrome

I've been playing with Nightly on and off for the past 6 months and I switched to Firefox Developer Edition as my daily driver whenever it switched over to using the new engine (~2 months ago) just to "try it out".

Two months later and I'm still "trying it out"! It's really that good. It is just a slight but very noticible speed increase and knowing that I'm not giving google allll my data without a bit of a struggle that makes me strongly reccomend it to anyone who will listen.

Pros:

Memory Usage, Privacy, Speed, UI

Cons:

Very rare render bugs.

Does the Firefox debugger work with `node --inspect` now?

IMO chrome is not just a browser. It’s the whole ecosystem that google has built around it which makes it hard to switch. So even if Firefox is faster it will take more than that to make me switch

@osunick 🎉🎉🎉 Awesome product! Keep on guys!! 💪💪

If only they had multiple accounts like chrome. I currently have about 26 of my 30+ google accounts loaded in chrome. If Firefox had multiple users with the ease of switching between them I would switch. Also Firefox needs to support HLS video streaming and give up on only supporting OGG.

Firefox Quantum is sleek, modern, and absolutley the fastest browser I have ever used. I am not one to abandon the products I love, but I ditched Chrome after about 3 minutes of use and have no plans on returning. Worth a download.

Pros:

Firefox quantum is insanely fast. I have never experienced a faster browser.

Cons:

Chrome offers a much more robust extension library, but apparently Foxified solves this.

This is actually noticeably faster. I don't think that I'll move from Safari but now I know another good alternative to recommend to people.

Direct shots at Google Chrome (see the video). Speed is a top priority for me, but I have so many Chrome Extensions that I don't want to lose. Request for product: Chrome Extension to Firefox Add-On converter.
