Flash plugin won't work right with 31.0, works fine with 30.0, is there a fix coming?
I have several Unitrends backup systems, which use flash for the Web GUI. After upgrading to Firefox 31.0, only one of four of these will load the GUI. This all works with IE, Chrome, and Firefox 30.0. My guess is that there is some legacy flash logic that does not work properly in 31.0. Currently, I have had to downgrade to Firefox 30.0 (no change to flash version, BTW).

You can check for problems with current Shockwave Flash plugin versions and try this:
- check for updates for your graphics drive drivers
https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration - disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
- disable hardware acceleration in the Flash plugin

This problem isn't about the flash plugin, everything else was the same, the flash plugin, the web GUIs using it, etc. The only difference that caused the problem was the upgrade to Firefox 31.0, and the only way I was able to resolve it was by downgrading to Firefox 30.0.
Furthermore, every other browser (IE, Chrome, etc.) works fine on this system using the same flash plugin, same web GUIs. The problem is specific to Firefox 31.0, so the problem needs to be resolved in Firefox.
IE uses a ActiveX version while Chrome comes with its own Pepper Plugin API Flash plugin and uses that by default instead of the one used by Firefox from Adobe. Even though they often times have same version numbers or close as you can see in http://www.adobe.com/software/flash/about/
