Pandora has stopped working under FF 52.0

[Rav]

Using Windows 7. After updating to Firefox 52.0 (32-bit), Pandora no
longer plays. I can log into my account, Pandora loads, it displays a
spinning record, but nothing plays. All the controls at the bottom of
the page (such as the Play button) are disabled. I restarted with all
add-ons disabled, and that didn't help. I made sure that Flash was
enabled for Pandora. I tried it under Internet Explorer and it works
there. It was working previously under Firefox, so other than updating
to Firefox 52.0 nothing else has changed. Thanks for any help.

Latest version of FF, I just downloaded and installed it.

Pandora works fine for me, but other than ask if you have the latest
Flash installed, I've no clue as to why it doesn't work for you.

Thanks, Ken. What you said gave me an idea, which was to create a new
test profile and try Pandora under that. And sure enough, it worked. I
looked at the entries I had in my user.js file to see if anything there
could be interfering. One of them caught my eye, which is a preference
to turn off media autoplay (media.autoplay.enabled, which I had set to
false). As soon as I turned that pref back to true, Pandora started
working. Why it prevents Pandora from working I don't understand, but
at least it now works. Unfortunately, the reason I had set that pref to
false was to prevent all the automatic playing of videos on web sites,
and now I have to live with that again. Oh well. Thanks again for your
help.

If you have the PrefBar extension installed, you can easily create a
checkbox to enable and disable autoplay.

I found a report in Bugzilla for this pref negatively affecting other
web sites. I've added a comment that it also affects Pandora.

Thanks! I downloaded PrefBar, copied the JavaScript checkbox, named it
AutoPlay and updated the preference it affects, and it works perfectly!

Would that be the Flash enable/disable check box you are referring to?

Thank you! Thank you! Thank you! Thank you! Thank you! Thank you!
Thank you, Rav! I have been searching for a fix for this for at least 6 months.
At first I couldn't find it though because a search for user.js didn't turn up anything related to the flash player but I noticed that the "media.autoplay.enabled" looked a lot like the entries I've seen in about:config so I looked and sure enough it was there and set to false.

A thousand thanks Rav!
