Performance in Firefox 45.6.0

I’m trying to test GoJS samples.
I found out that it’s very slowly in Firefox!? (specially in Update Demo GoJS Sample)
Could you give me some details?

Best Regards,

I normally use Firefox, and I’m running version 51 right now. I find it’s pretty fast on various machines. It might not be quite as fast as the other browsers, but I find it very responsive when running any GoJS app.

Version 45 wasn’t that long ago, but we’ve never really had any performance problems in Firefox.

Hello Walter,
Thank you for your response.
It was my problem, it works with new Version(52.0) very good.
