Hi,

I have something strange for the last 2 weeks since the 56 update, firefox was running fine when looking at youtube movies and fast.
Since this weekend, firefox freezes on youtube content for a few seconds and then continous.
I did just have a windows 10 1709 update.
Firefox is version 56.0.2.
I have an RX480 with the latest graphic drivers and i am doing some testing with hardware acceleration enabled and disabled for firefox (tools/options/ performance).
I am not sure where the problem may be.
Anybody experiences the same issues?

Please help.
Thanks!

I didn't find the right solution from the Internet.
