Ignoring redeclaration error in Firefox console

[esat-karakaya]

Hi Firefox team
When I write a function in the browser dev tools, do something wrong and then redeclare the same function Firefox throws an error. But this is the browser console and I'm just messing around. The same thing applies to variables declared with let, const and var. Can Firefox ignore with what keywords the variables are assigned or declared if the code was written in the browser dev tools?
