Firefox Quantum - The newest, fastest version of Firefox yet. 🔥🦊

Makes my i7 MBPr 2015 slow as hell

This release is a stepstone. :)

Pros:

Efficient

Cons:

Impossible to drag an image from browser to desktop

this is it bravo @nick Nguyen from firefox your new browser Firefox Quantum is amazing and excellent, actually, i have been following up the news and it is not a piece of words, but a promise that was kept and I tried it,things opens like it superman or wonder woman, damn men, just what I do want,it a through definition of a browser, even though i have been using my chromebook, but i just switch to windows..because of this new browser.... hey firefox developers thanks, men, firefox quantum is the fastest thing on earth now, i hope to see more improvement.... i also hope google, apple, brave, blink, ghost, opera mini will link from you guys and improve the system,. i can now open more system and my system never hugs

am i the only one for whom it works way slower than both safari and chrome?

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

Frankly, the only really fast browser today is Brave. Incomparably faster.

Still can't compete with Chrome's dev tools and extensions ecosystem.

Happy to now use just one browser across all my machines!

Pros:

Lighter: Can finally run firefox on machines with limited (and capped) amounts of RAM

Cons:

No cons yet, but will update here when I feel something is relevant

Can someone with an eye for detail who has test driven Firefox Quantum for a while comment on the accuracy of rendering and on the responsiveness of interaction? These things matter so much more than a 0.1s faster load time for me.

One of my computers built on the platform x86 and Core2Duo. I have endless crash on new FFQ. Crash, crash and crash. Over and over and over again. Opening pages are really slowly compared with old FF. Don't use this browser on old or weak computers. Support Mozilla did not respond to my complaints.

Sooo... Non-usable now. I'm waiting for optimization updates and i have to use Chromium now. New Firefox is really raw.

How to downgrade to old FF and how to disable automatic upgrade to new FF?

Pros:

I don't like anything absolutely

Cons:

Now it's a raw alpha version without optimization.
