Go to https://random-items.erosson.org/
Enter 100000 in the input box.
Click on roll.
The page will take a 4-5 seconds to run. Wait.
Now click on any generated link (e.g. "Rare Hard Leather Armor")
ER: The link opens
AR: It takes 9 second to open
Chrome : https://share.firefox.dev/3tcl4KP (200ms-400ms)
Nightly: https://share.firefox.dev/3RwQUwc (9 seconds)
(This may be a DOM issue)
Similar performance charactersticks exist in a build from Jan2020. So this is not a new regression.

And a more extreme example : https://share.firefox.dev/48smv8o (3+ minutes). This happens when you input 1000000 in the input box and roll.
And a less extreme example : https://share.firefox.dev/48tDzKY with 10000 roll value.

It spends most of the time in DOM code in/under nsParentNodeChildContentList::ValidateCache. Probably not enough time in actual JS code to tier up.
