Why is Firefox Developer more stable and faster than regular Firefox?

So, I've have some great experiences with regular Firefox. It works great, nice themes, good plugins, security etc., but there's one thing that bothers me of Firefox on EVERY computer on EVERY operating system. Whenever I install Firefox, it is already slow, it stutters sometimes and sometimes it freezes. And it's not only my problem, many of my friends and classmates are using Chrome at this moment, because they complain about speed of Firefox. Now, for me that's not problem, I'm not patient person, but surely it is browser that will protect my privacy as opposed to Chrome.

Recently, somewhere, I saw download link saying something like "Mozilla Developer, for people like you", or something alike, I installed it and man, that browser is like 10x faster than regular Firefox AND Chrome AND Safari, I mean, this speed is outrageous! It's great, no sarcasm!

I don't get it, why is regular Firefox so slow and Firefox Developer so frickin' fast? Why? Can you maybe base your next Firefox update to Firefox Developer?

Sincerely Mozilla Firefox Developer lover. *muah*

Firefox Developer Edition is a pre-release version of Firefox. So what you see in Developer edition is what will be released to regular Firefox in about 12 weeks (we do releases every 6 weeks, and Dev edition is two releases ahead of release)

Dev Edition also uses a fresh profile, which can be faster than your old profile that is full of old data.

Try to disable OMTC and leave hardware acceleration in Firefox enabled.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

@Tyler Downer Oke, good to hear it's next release of Firefox. But my profile isn't full, I don't really log in, totally fresh install of Firefox are mostly really sluggish. Mozilla really outdid themselves in speed and stability!! Great! A++ Mozilla!

Developer Edition is the only version that creates a new Profile upon installation. All other versions [Firefox Release, Beta, the old Aurora, and Nightly a1] will use the existing Profile, and it is up to the user to create new or additional Profiles [if they run different versions of Firefox that are installed at the same time.]
