When Shockwave Flash is enabled it causes flash videos to lag
I just got a new laptop (Acer) with Windows 10. In Firefox 42.0, all youtube videos play fine (because of HTML5, I assume), but Flash videos lag. I set Shockwave Flash in the plugin list to 'Never Activate' and that fixes the lagging. But now some videos on other sites don't show up at all because they need Shockwave Flash (they also lagged before, for your information).
What do you think the problem is? I obviously want to have it enabled all the time, but without all that lagging.

I've found the problem. It was the Acer's crappy CPU. When playing Youtube videos Firefox took the CPU to 95% most of the time, and with Flash it was even worse because of Firefox and Flash player running at the same time.
So my problem should be fixed by buying a better laptop. That's what I get for assuming every laptop these days can run Youtube videos.
Thanks for the help, and I hope that what I found helps other people too who have this problem.

If you have problems with current Shockwave Flash plugin versions then check this:
- see if there are updates for your graphics drivers

- disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

- disable hardware acceleration in the Flash plugin

I just updated my drivers to the latest ones, tried disabling protected mode and tried disabling hardware acceleration. Nothing worked. The problem still persists.
And I just found out that youtube videos are only fine up to 480p. Any higher and they start lagging too.
And any quality fullscreen lags too.
Perhaps this is a web site issue.
Do you think so? I thought it was pretty funny when I tested other browsers. Firefox played youtube fine and flash laggy, Chrome had great flash and laggy youtube and Edge had no problem with either.
I'm really not looking forward to Edge being my choice, hehe.
I'm gonna try some more of those links you posted last. Maybe I'll find the problem there.

That was very good work. Well Done.
