Tip – Fixing Quicktime on Mac Firefox
Quicktime video playback wasn’t working at all within Firefox on the Mac. Safari was fine. I did the usual thing and Googled the problem — always a good idea with any tech issue — and found lots of people had the same experience. But I couldn’t see a fix anywhere.
I found Adblock (original add-on) was the cause. I uninstalled it and I switched to Adblock Plus instead, and Quicktime now works fine in Firefox.
