Flash doesn't work
Within the past week, Flash completely stopped working in Firefox 49.0.2 (64-bit) on Windows 7. I can get it working at, e.g., http://www.adobe.com/software/flash/about/ if I remove all of my extensions, but as soon as I reinstall, say, Firebug, it's gone again.
Can anyone help me troubleshoot? Thanks!

Some users are having problem with Flash due to an incompatibility with a new feature. You could try turning it off as follows:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
(2) In the search box above the list, type or paste async and pause while the list is filtered
(3) Double-click the dom.ipc.plugins.asyncdrawing.enabled preference to switch the value from true to false
This might not take effect until the next time you exit Firefox and start it up again.
Does that help?

Thanks jscher2000, that fixed it!
Should I be concerned at all about leaving dom.ipc.plugins.asyncdrawing.enabled set to false permanently?
Well, I don't think any sites depend on it, it's just meant to allow some parts of the media to load more quickly than others rather than all waiting their turn. What you get by turning it off is how it worked in Firefox 48. Hopefully in a couple cycles the bugs will all be worked out.
