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.

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.

Firefox 57 is seriously a gamechanger. It is ridiculously fast + nice sleeping at night knowing that Google isn't stealing absolutely every piece of information about me

As a Chrome user is switching to Firefox worth it?

Ask search? Really?

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.

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;

🔥 @firefox Quantum is finally launching today! I have been using Firefox Quantum for over 1 month now and I am thoroughly impressed - faster performance, doesn't hog on my computer memory, and not to forget the all-new Firefox Screenshots feature available on Firefox Quantum. Don't forget to give it a try when it's available today. 👏

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

I have used firefox almost exclusively. Fooled around with chrome for some time but I wasn't happy with the memory usage on my machine. The only thing I missed in firefox was the speed. Chrome used to perform better than firefox but that has changed now!

Pros:

It is faster than ever.

Cons:

I am not sure I am into the whole "integrating external services intro the browser".

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.

yet firefox doesn't give a sh!t about webp images. WTF firefox?

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.

OMG, I switched Chrome to Opera It Seems Like Opera is Great at many things I think Mozilla Should Learn from Opera of course Speed Matters But that one thing doesn't matter with Opera's Stand Alone Features Like opt-out video Player, Inbuilt Messager,etc.I Hate This

Pretty impressive the work Firefox has done here - love the UX/UI overhaul, and the speed is _very_ apparent. I think it's important not to just measure on RAM/CPU usage but overhaul end-user responsiveness - after using this for the last few days it's incredibly apparent how fast Firefox Quantum is at a) loading pages and b) always being performant in the UI. Big fan!

I don't know how but it's really fast

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.

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.

it's fast

I moved from Firefox (after 10 years of using it) to Chrome. Chrome to Opera. Opera to Safari. Now, two years later I'm back on Firefox 🤘
