Hello,

After the last updates of Firefox and flash, I cannot play any flash game i.e. all of them work, but VERY slow, laggy, stutter, etc. Main game in question that I play is Forge of Empires.

I have already tried the steps in this: https://support.mozilla.org/en-US/questions/1174471 and other mozilla support articles and none have helped / reinstalling / dom.ipc.plugins.asyncdrawing.enabled set to false, etc. Everything works FINE in Chrome and Waterfox. Just FF is EXCRUCIATINGLY slow. Even with ALL add-ons and plug ins (except flash of course) disabled.

Have seen the plugin.exe go over 5 GB. WTH?

I use: Windows 7 (64 bit) Firefox (latest version) Flash player (latest version)

Thanks you for your help in advance!

HI please try : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0.2 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.
