Ummmm, there's a new build most every day. Are you claiming this will be made available to Fast Ring or just announcing what we can all see on Buildfeed?
No. 44.0.1 nor today's Flash update addressed it, so I guess the best chance now is a new Windows build. ProtectedMode=0 is still the only fix (FF x64 may not be affected per an earlier post).
AFAIK flash play for FF is not updated by MS (MS updates flash play for IE with Windows Update). FF 40.0.1 update flash play to version 306.
not on redstone but latest win 10 pro updated today to 10586.104 and have been using flash player betas for a while now on win 10 and server 2012 r2 so if latest stable ff flash player not working, have you tried the betas v21.x.x dated feb 3 on labs.adobe.com to see if those work until new build of redstone comes out
I can't recall the last time that I saw MS push out an IE Flash update for an Insider build, but it is updated when you update the build. As for FF, it doesn't update FF's Flash--Adobe's automatic update tool is what gave you the 306 version.
Ninite failed to update k-lite within the previous build (couldn't confirm version) and a manual update gave me reg ocx errors, which I could only ignore. With the new build I was able (again) to upgrade the k-lite-pack.
Maybe it was the update itself and only a coincidence ? Ninite works at least 99% of the time without any issues for me too. If I get something similar in the near future, then I will take a screenshot of it to show you the error's from Ninite and evtl. a separate installer, if available. Maybe we are able to pin-point the issue.
