Freeze when buying buildings in firefox

[Paraplegix]

When frozen cookie is loaded, buying any building make the game freeze for half or one second.

I'm running lastest version of cookie clicker, with firefox 83.0 (64 bits)

Looking at the performance tool in debug console, it looks like the freeze is happening FC is trying to figure out what is the next best purchase

I can't reproduce this issue. When does this happen? after you ascended or even if you are longer into a run?
