Newest Firefox always unstable, buggy, like a Beta release

Question

I have been using Firefox for years, and generally like it above all else (currently running 11.0). However, I have had to disable the updates of any kind because ''every'' new release of Firefox is unstable. Maybe it works for an hour or a day, but it will crash or screw up in some fashion. I have chosen to always run an older version of Firefox because of this, and always turn off auto updates.
Cant you guys get a '''good, stable product '''before you release it? Same with the updates, they are almost always highly unstable, and if your unlucky enough to have auto update enabled, you can bring yourself some serious problems.
It would be really nice to have some Quality Control as far as your new releases are concerned. Buggy, crashy releases only serve to frustrate most of us. We would really like to trust you, but with each buggy release you undermine our faith in your ability to keep us up to date and, most importantly, Secure. We know you cant account for each and every systems unique set up, but you can do better than whats been happening for the last few years (yes, its been this way or as long as I can remember using Firefox).
How are we going to fix this? Those who like Beta versions can have them if they want them, but I believe most of us average users want a good, secure, stable release each and every time, which has never been the case with Firefox. There's got to be a better way.

Answer 1

Every change in Firefox is tested by hundreds (thousands?) of people, but even the largest beta testing program will miss things because of the unique interaction of systems, sites, and add-ons for hundreds of millions of Firefox users.
If you would like assistance with particular issues, this is a good site for that.
And of course, I would be remiss in failing to point out that Firefox 11 has some known and publicly disclosed security vulnerabilities, so it's worth making an effort to update if you can.
Finally, I'll note that there is a separate release schedule for business users that insist on a product with less frequent changes. Maybe you'd be interested in that? [http://www.mozilla.org/en-US/firefox/organizations/faq/ Firefox Extended Support Release FAQ]
