"Don't they test before release?"
None, and Firefox has been my browser, like, forever b/c I hated IE for the same amount of time.
I can't watch videos on Amazon Prime. I was upset with Amazon b/c I thought the problem was on their end until I tried another browser. I just found out that it doesn't work with Youtube, either. If it has this basic problem, what other problems does it have that I haven't noticed yet? Quality Control, anyone?
I can't watch videos and some audio players refuse to work. Some online ads are invisible.
They have to fix this. Every other browser out there plays video just fine. If you like FF, find an older version.
