What does this version break?

Does it actually work with Adobe Flash now or do we have to wait for a Flash update?

Those 2 have been fighting each other since around FF version 12.

How many extensions/add-ons no longer work now?

Firefox has become exasperating with the rapid release insanity. That may be fun for programming nerds, but it is a massive hassle for anyone trying to use FF productively.

Which extensions have been breaking for you?

I use several and haven't had any trouble with them in quite a while.

I had to uninstall Firefox, which has always been my go to browser with this release. I had two problems:

1. It prevented McAfee scan from starting

2. Pages using JavaScript not longer function

Sadly I cannot live with either of these errors, so I had no choice except to dump Firefox.
