Crashes with noscript/FF49 on various sites

The last days I have repeated crashes of firefox on various sites using noscript. An example is:
https://www.modhoster.de/mods/vehicle-sort
Allowing sripts for 'modhoster.de' temporarily lets firefox crash.
When disabling noscript completely, everything works fine.
I created also a fresh firefox-profile, but this did not help either.
Not sure when these crashes appeared exactly, but it must be sometimes within the last 3 weeks.

(In a not see clean Profile...)
First attempt, Allow Globally, I was running 50% CPU (100% of 1 of 2 cores), & I gather that never would have subsided.
Revoking that, & only allowing modhoster.de, it much better behaved.
Initially, CPU usage was quite variable, but after a while setting down to virtually nothing.
Not seeing memory usage increase.
(Kind of seem to recall certain other particular sites, that when particular domains were allowed, prolonged or even unending high CPU usage ensued? Maybe it was with some of the bank sites...?)

A number of huge messages are hitting error console.

Hmm.
Clear cache
Do a Reset of NoScript (settings)
Restart (SeaMonkey) & load modhoster.de
Allow modhoster.de
Then Allow Globally
and its not too bad actually.
I've got Flash set to ask.
Site does have some scrolling (I'm going to call them) "marquees".
Otherwise, I'm seeing variable CPU usage; from a few to ~20%, but no memory growth.
So at present, its not looking awful.
And I'm not seeing the prolonged high CPU usage like I saw on my initial load of the site.

And that'd be it. This is a site problem, they are using extremely unsafe practice to pass data around between domains, and NoScript is blocking it for your safety.
This has come up before

You can deal with this specific instance by:
