I am trying to add this slider to make a noise maker(with the new save feature).but iMouse seems no work,the slider can not be moved.

Sorry, had a busy couple of weeks.
It appears to me that the iMouse uniform might be in a different space than what it is on the Shadertoy website. That'd be an obvious compatibility issue.
I'll take a look at comparing the two and then we can think about if we want to fix it and thus potentially break shaders written in the extension or just advise about the discrepancy
