Unusual JS behavior in Firefox, why is that?

Question

JavaScript

Good day, gentlemen and ladies!
Here's what I have. There is JS shitty code: as far as I figured out, the causal place is a loop with a large number of iterations. Although there are many iterations, they do not contain heavy operations, and the cycle runs quickly on chrome, the 11th explorer, the last firelis (under ubuntu and wine7), but on wine8 the same last firelis does not want to do anything, they say "Looks like the script executing on this page is busy...".
Can anyone explain to a noob what kind of feature this is?

Answer 1

Will you show me the code?

Answer 2

Fx has a script execution time limit of 10 s. You can increase it by setting the about:config variable
to the desired value. (It won't be faster, but it won't break as often either.)
