RESOLVED DUPLICATE of bug 1513966

People

(Reporter: gserg.g, Unassigned)

Details

(Keywords: flashplayer)

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0

Steps to reproduce:

After updating from 64.0.2 to 65.0 on Windows 7 x64, many Flash games are broken. Cannot save or load, many hang during startup unable access their files. Using Procmon, I can see a lot of ACCESS DENIED entries for paths like C:\Users\XXXXXX\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\NB4CWQC4\XXXXXXXX\gamez\0020\4650\live. I'm aware this problem existed in Firefox for Mac, now it appears it has come to Windows.

Actual results:

Flash games do not work.

Expected results:

Flash games work like they did in 64.0.2.

Actually that worked for me.
Firefox needs to be restarted.
